Abstract
计算未验证的 OGNL 表达式可能导致执行远程代码。
Explanation
对象图导航语言 (OGNL) 是一种针对 Java 的开源表达式语言 (EL),它允许在 Struts 2 Value Stack 上下文中计算 EL 表达式。允许根据 Value Stack 计算未经验证的表达式,这将使攻击者有权修改系统变量或执行任意代码。

在以下示例中,应用程序使用由用户控制且未经验证的数据创建 OGNL 表达式的计算:

OgnlContext ctx = new OgnlContext();
String expression = request.getParameter("input");
Object expr = Ognl.parseExpression(expression);
Object value = Ognl.getValue(expr, ctx, root);
System.out.println("Value: " + value);


攻击者可以提交以下表达式以在应用程序服务器环境中执行任意代码:

(#rt = @java.lang.Runtime@getRuntime(),#rt.exec("calc.exe"))

Abstract
双重 OGNL 计算允许攻击者在控制第一次计算的输出时,计算任意 OGNL 表达式。
Explanation
应用程序在两次计算 OGNL 表达式的 Struts 标签中使用强制 OGNL 表达式 (%{expr})。控制第一次计算结果的攻击者可能会控制要在第二次 OGNL 计算中计算的表达式,并注入任意 OGNL 表达式。

示例 1:已知 redirectAction 结果可计算其参数两次。在这种情况下,攻击者可以通过提供 redirect 请求参数,控制 actionName 参数中强制 OGNL 表达式的结果。


...
<action name="index" class="com.acme.MyAction">
<result type="redirectAction">
<param name="actionName">${#parameters['redirect']}</param>
<param name="namespace">/foo</param>
</result>
</action>
...


Struts 2 代码将在内部计算 %{#parameters['redirect']} 表达式,该表达式返回的用户控制字符串将作为 OGNL 表达式进行计算,从而允许攻击者计算任意 OGNL 表达式。

Abstract
Struts 2 应用程序启用动态方法调用,众所周知,在某些 Struts 2 版本中,很容易受到 OGNL Injection 攻击。
Explanation
Struts 2 引入了名为“动态方法调用”的功能,允许操作公开 execute() 以外的方法。如果启用“动态方法调用”,可在操作 URL 中使用 ! (bang) 字符或 method: 前缀,以在操作中调用任何公共方法。在 Struts 2 版本 2.3.20 中,先前基于反映调用替代方法的机制将替换为使用 OGNL,这样攻击者将可以提供恶意 OGNL 表达式而不是替代方法名称。

Abstract
应用程序采用开发模式 (devMode) 部署,允许在服务器上执行任意命令及泄露有关应用程序编码方法的详细信息。
Explanation
Struts 2 包含名为 devMode(开发模式)的设置。启用此设置后,Struts 2 将提供额外的日志记录和调试信息,这样可以显著加快开发速度,但却会对性能和安全性产生极大的影响。devMode 将调试级别或通常可忽略的问题升级为通常在正常模式下不会抛出的异常。

devMode 还启用了一些调试功能,使开发人员能够检查值堆栈中存储的变量。这些功能可以使用 debug 请求参数触发:
- debug=console 将弹出 OGNL 评估控制台,允许开发人员对服务器上的任意 OGNL 表达式进行评估。
- debug=command 将允许开发人员提交任意 OGNL 表达式,以使用请求参数 expression 进行评估。
- debug=xml 可将参数、上下文、会话和值堆栈转储为一个 XML 文档。
- debug=browser 可将参数、上下文、会话和值堆栈转储在一个可浏览的 HTML 文档中。

Abstract
如果允许未验证的输入控制重定向机制所使用的 URL,可能会有利于攻击者发动钓鱼攻击。
Explanation
通过重定向,Web 应用程序能够引导用户访问同一应用程序内的不同网页或访问外部站点。应用程序利用重定向来帮助进行站点导航,有时还跟踪用户退出站点的方式。当 Web 应用程序将客户端重定向到攻击者可以控制的任意 URL 时,就会发生 Open redirect 漏洞:

攻击者可能利用 Open Redirect 漏洞诱骗用户访问某个可信赖的站点的 URL,然后将他们重定向到恶意站点。攻击者通过对 URL 进行编码,使最终用户很难注意到重定向的恶意目标,即使将这一目标作为 URL 参数传递给可信赖的站点时也会发生这种情况。因此,Open Redirect 通常被作为网络钓鱼诈骗的一部分被滥用,攻击者通过这种方式来获取最终用户的敏感数据。

例 1:以下 ABAP 代码会在用户单击链接时,指示用户浏览器打开从 dest 请求参数中解析的 URL。


...
DATA: str_dest TYPE c.

str_dest = request->get_form_field( 'dest' ).
response->redirect( str_dest ).
...


如果受害者收到一封电子邮件,指示其打开“http://trusted.example.com/ecommerce/redirect.asp?dest=www.wilyhacker.com”链接,该用户就有可能会单击该链接,因为他会认为该链接会转到可信赖的站点。然而,当受害者单击该链接时,Example 1 中的代码就会将浏览器重定向到“http://www.wilyhacker.com”。

很多用户都被告知,要始终监视通过电子邮件收到的 URL,以确保链接指向一个他们所熟知的可信赖站点。尽管如此,如果攻击者对目标 URL 进行 16 进制编码:
"http://trusted.example.com/ecommerce/redirect.asp?dest=%77%69%6C%79%68%61%63%6B%65%72%2E%63%6F%6D"

那么,即使再聪明的最终用户也可能会被欺骗,打开该链接。

Abstract
文件将未验证的数据传递给 HTTP 重定向机制。
Explanation
如果允许未验证的输入控制重定向机制所使用的 URL,可能会有利于攻击者发动钓鱼攻击。通过重定向,Web 应用程序能够引导用户访问同一应用程序内的不同网页或访问外部站点。应用程序利用重定向来帮助进行站点导航,有时还跟踪用户退出站点的方式。当 Web 应用程序将客户端重定向到可能由攻击者控制的任意 URL 时,就会发生 Open Redirect 漏洞。

攻击者可能利用 Open Redirect 漏洞诱骗用户访问某个可信赖的站点的 URL,然后将他们重定向到恶意站点。攻击者通过对 URL 进行编码,使最终用户很难注意到重定向的恶意目标,即使将这一目标作为 URL 参数传递给可信赖的站点时也会发生这种情况。因此,Open Redirect 通常被作为网络钓鱼诈骗的一部分被滥用,攻击者通过这种方式来获取最终用户的敏感数据。

示例 1:以下 Visualforce 操作方法返回一个 PageReference 对象,其中包含来自 dest 请求参数的 URL。


public PageReference pageAction() {
...
PageReference ref = ApexPages.currentPage();
Map<String,String> params = ref.getParameters();
return new PageReference(params.get('dest'));
}


如果受害者收到一封电子邮件,指示其打开“http://trusted.vf.force.com/apex/vfpage?dest=www.wilyhacker.com”链接,该用户就有可能会单击该链接,因为他认为他们将转到可信赖的站点。然而,当受害者单击该链接时,Example 1 中的代码就会将浏览器重定向到“http://www.wilyhacker.com”。

很多用户都被告知,要始终检查通过电子邮件收到的 URL,并确保链接指向他们知道的可信赖的站点。尽管如此,如果攻击者对目标 URL 进行以下编码:

desc.dataflow.dotnet.open_redirect
Abstract
如果允许未验证的输入控制重定向机制所使用的 URL,可能会有利于攻击者发动钓鱼攻击。
Explanation
通过重定向,Web 应用程序能够引导用户访问同一应用程序内的不同网页或访问外部站点。应用程序利用重定向来帮助进行站点导航,有时还跟踪用户退出站点的方式。当 Web 应用程序将客户端重定向到可能由攻击者控制的任意 URL 时,就会发生 Open Redirect 漏洞。

攻击者可能利用 Open Redirect 漏洞诱骗用户访问某个可信赖的站点的 URL,然后将他们重定向到恶意站点。攻击者通过对 URL 进行编码,使最终用户很难注意到重定向的恶意目标,即使将这一目标作为 URL 参数传递给可信赖的站点时也会发生这种情况。因此,Open Redirect 通常被作为网络钓鱼诈骗的一部分被滥用,攻击者通过这种方式来获取最终用户的敏感数据。

示例 1:以下 JSP 代码会在用户单击相关链接时,指示用户的浏览器打开从 dest 请求参数解析的 URL。


...
final server = await HttpServer.bind(host, port);
await for (HttpRequest request in server) {
final response = request.response;
final headers = request.headers;
final strDest = headers.value('strDest');
response.headers.contentType = ContentType.text;
response.redirect(Uri.parse(strDest!));
await response.close();
}
...


如果受害者收到一封电子邮件,指示其打开“http://trusted.example.com/ecommerce/redirect.asp?dest=www.wilyhacker.com”链接,该用户就有可能会单击该链接,因为他会认为该链接会转到可信赖的站点。然而,当受害者单击该链接时,Example 1 中的代码就会将浏览器重定向到“http://www.wilyhacker.com”。

很多用户都被告知,要始终检查通过电子邮件收到的 URL,以确保链接指向他们知道的可信赖的站点。尽管如此,如果攻击者对目标 URL 进行 16 进制编码:
"http://trusted.example.com/ecommerce/redirect.asp?dest=%77%69%6C%79%68%61%63%6B%65%72%2E%63%6F%6D"

那么即使是精明的最终用户也可能被骗至访问该链接。

desc.dataflow.javascript.open_redirect
Abstract
如果允许未验证的输入控制重定向机制所使用的 URL,可能会有利于攻击者发动钓鱼攻击。
Explanation
通过重定向,Web 应用程序能够引导用户访问同一应用程序内的不同网页或访问外部站点。应用程序利用重定向来帮助进行站点导航,有时还跟踪用户退出站点的方式。当 Web 应用程序将客户端重定向到攻击者可以控制的任意 URL 时,就会发生 Open redirect 漏洞:

攻击者可能利用 Open Redirect 漏洞诱骗用户访问某个可信赖的站点的 URL,然后将他们重定向到恶意站点。攻击者通过对 URL 进行编码,使最终用户很难注意到重定向的恶意目标,即使将这一目标作为 URL 参数传递给可信赖的站点时也会发生这种情况。因此,Open Redirect 通常被作为网络钓鱼诈骗的一部分被滥用,攻击者通过这种方式来获取最终用户的敏感数据。

例 1:以下 PHP 代码会在用户单击链接时,指示用户浏览器打开从 dest 请求参数中解析的 URL。


<%
...
$strDest = $_GET["dest"];
header("Location: " . $strDest);
...
%>


如果受害者收到一封电子邮件,指示其打开“http://trusted.example.com/ecommerce/redirect.php?dest=www.wilyhacker.com”链接,该用户就有可能会单击该链接,因为他会以为该链接会转到可信赖的站点。然而,当受害者单击该链接时,Example 1 中的代码就会将浏览器重定向到“http://www.wilyhacker.com”。

很多用户都被告知,要始终监视通过电子邮件收到的 URL,以确保链接指向一个他们所熟知的可信赖站点。尽管如此,如果攻击者对目标 URL 进行 16 进制编码:
"http://trusted.example.com/ecommerce/redirect.php?dest=%77%69%6C%79%68%61%63%6B%65%72%2E%63%6F%6D"

那么,即使再聪明的最终用户也可能会被欺骗,打开该链接。

desc.dataflow.ruby.open_redirect
Abstract
如果允许未验证的输入控制重定向机制所使用的 URL,可能会有利于攻击者发动钓鱼攻击。
Explanation
通过重定向,Web 应用程序能够引导用户访问同一应用程序内的不同网页或访问外部站点。应用程序利用重定向来帮助进行站点导航,有时还跟踪用户退出站点的方式。当 Web 应用程序将客户端重定向到攻击者可以控制的任意 URL 时,就会发生 Open redirect 漏洞:

攻击者可能利用 Open Redirect 漏洞诱骗用户访问某个可信赖的站点的 URL,然后将他们重定向到恶意站点。攻击者通过对 URL 进行编码,使最终用户很难注意到重定向的恶意目标,即使将这一目标作为 URL 参数传递给可信赖的站点时也会发生这种情况。因此,Open Redirect 通常被作为网络钓鱼诈骗的一部分被滥用,攻击者通过这种方式来获取最终用户的敏感数据。

示例 1:以下 Paly 控制器方法指示用户浏览器打开从 dest 请求参数中解析的 URL。


def myAction = Action { implicit request =>
...
request.getQueryString("dest") match {
case Some(location) => Redirect(location)
case None => Ok("No url found!")
}
...
}


如果受害者收到一封电子邮件,指示其打开“http://trusted.example.com/ecommerce/redirect.asp?dest=www.wilyhacker.com”链接,该用户就有可能会单击该链接,因为他会认为该链接会转到可信赖的站点。然而,当受害者单击该链接时,Example 1 中的代码就会将浏览器重定向到“http://www.wilyhacker.com”。

很多用户都被告知,要始终监视通过电子邮件收到的 URL,以确保链接指向一个他们所熟知的可信赖站点。尽管如此,如果攻击者对目标 URL 进行 16 进制编码:
“http://trusted.example.com/ecommerce/redirect.asp?dest=%77%69%6C%79%68%61%63%6B%65%72%2E%63%6F%6D”;

那么甚至精明的最终用户也可能会被轻易引入该链接。

示例 1:下面的代码可处理使用应用程序的自定义 URL 方案的任何请求,设置 requestToLoad 来指向原始 URL 的“dest”参数(如果存在该参数,如果不存在则指向使用 http:// 方案的原始 URL),并最终在 WKWebView 内加载此请求:

AppDelegate.swift:

...
let requestToLoad : String

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
...
if let urlComponents = NSURLComponents(URL: url, resolvingAgainstBaseURL: false) {

requestToLoad = request
break
}
}
}
}
if requestToLoad == nil {

ViewController.swift

Abstract
该程序从分配的内存边界之外读取数据。
Explanation
Buffer overflow 可能是人们最熟悉的一种软件安全漏洞。虽然绝大多数软件开发者都知道什么是 Buffer overflow 漏洞,但是无论是对继承下来的或是新开发的应用程序来说,Buffer overflow 攻击仍然是一种最常见的攻击形式。对于这个问题出现的原因,一方面是造成 buffer overflow 漏洞的方式有很多种,另一方面是用于防止 buffer overflow 的技术也容易出错。

在一个典型的 buffer overflow 攻击中,攻击者将数据传送到某个程序,程序会将这些数据储存到一个较小的堆栈缓冲区内。结果,调用堆栈上的信息会被覆盖,其中包括函数的返回指针。数据会被用来设置返回指针的值,这样,当该函数返回时,函数的控制权便会转移给包含在攻击者数据中的恶意代码。

虽然这种类型的堆栈 buffer overflow 在某些平台和开发组织中十分常见,但仍不乏存在其他各种类型的 buffer overflow,其中包括堆 buffer overflow 和 off-by-one 错误等。有关 buffer overflow 如何进行攻击的详细信息,许多优秀的著作都进行了相关介绍,如 Building Secure Software [1]、Writing Secure Code [2] 以及 The Shellcoder's Handbook [3]。

在代码层上,buffer overflow 漏洞通常会违反程序员的各种假设。C 和 C++ 中的很多内存处理函数都没有执行边界检查,因而可轻易地超出缓冲区所操作的、已分配的边界。即使是边界函数(如 strncpy()),使用方式不正确也会引发漏洞。对内存的处理加之有关数据段大小和结构方面所存在种种错误假设,是导致大多数 buffer overflow 漏洞产生的根源。

在这种情况下,该程序会从分配的内存边界之外进行读取,这会允许攻击者访问敏感信息、引入错误的行为,或者造成程序崩溃。

例 1:在以下代码中,memcpy() 调用会从分配的 cArray 边界之外读取内存,其中包含 char 类型的 MAX 元素,而 iArray 包含 int 类型的 MAX 元素。


void MemFuncs() {
char array1[MAX];
int array2[MAX];
memcpy(array2, array1, sizeof(array2));
}
例 2:以下短程序在使用分析用的字元常数 memchr() 时,将一个不可信赖的命令行参数作为搜索缓冲区使用。


int main(int argc, char** argv) {
char* ret = memchr(argv[0], 'x', MAX_PATH);
printf("%s\n", ret);
}


该程序本来是要通过搜索 argv[0] 数据直至一个常数字节来输出 argv[0] 的一个子字符串。然而,因为(常数)字节数可能大于为 argv[0] 分配的数据,搜索可能在分配给 argv[0] 的数据之外进行。当在 argv[0] 中无法找到 x 时会发生这种情况。

Abstract
程序从分配的内存边界之外读取数据。
Explanation
Buffer overflow 可能是人们最熟悉的一种软件安全漏洞。虽然绝大多数软件开发者都知道什么是 Buffer overflow 漏洞,但是无论是对继承下来的或是新开发的应用程序来说,Buffer overflow 攻击仍然是一种最常见的攻击形式。对于这个问题出现的原因,一方面是造成 buffer overflow 漏洞的方式有很多种,另一方面是用于防止 buffer overflow 的技术也容易出错。

在一个典型的 buffer overflow 攻击中,攻击者将数据传送到某个程序,程序会将这些数据储存到一个较小的堆栈缓冲区内。结果,调用堆栈上的信息会被覆盖,其中包括函数的返回指针。数据会被用来设置返回指针的值,这样,当该函数返回时,函数的控制权便会转移给包含在攻击者数据中的恶意代码。

虽然这种类型的 off-by-one 错误在某些平台和开发组织中十分常见,但仍不乏存在其他各种类型的 buffer overflow,其中包括堆栈 buffer overflow 和堆 buffer overflow 等。有关 buffer overflow 如何进行攻击的详细信息,许多优秀的著作都进行了相关介绍,如 Building Secure Software [1]、Writing Secure Code [2] 以及 The Shellcoder's Handbook [3]。

在代码层上,buffer overflow 漏洞通常会违反程序员的各种假设。C 和 C++ 中的很多内存处理函数都没有执行边界检查,因而可轻易地超出缓冲区所操作的、已分配的边界。即使是边界函数(如 strncpy()),使用方式不正确也会引发漏洞。对内存的处理加之有关数据段大小和结构方面所存在种种错误假设,是导致大多数 buffer overflow 漏洞产生的根源。

在这种情况下,该程序会从分配的内存边界之外进行读取,这会允许攻击者访问敏感信息、引入错误的行为,或者造成程序崩溃。

示例 1:以下代码连续地间接引用 char 五元数组,最后一个引用会引入 off-by-one 错误。


char Read() {

char buf[5];
return 0
+ buf[0]
+ buf[1]
+ buf[2]
+ buf[3]
+ buf[4]
+ buf[5];
}

Abstract
该程序使用带符号的比较来检查稍后会被视为不带符号的值。这会导致程序从分配的内存边界之外读取数据。

示例 1:以下代码尝试通过检查从 getInputLength() 中读取的不可信的值,验证其是否小于目标缓冲区 output 的大小,来避免从边界之外进行读取的 buffer overflow。然而,因为 lenMAX 之间比较的是带符号的值,所以如果 len 为负值,在其转换为 memcpy() 不带符号的参数时,将会变成一个超级大的正数。


void TypeConvert() {
char input[MAX];
char output[MAX];

fillBuffer(input);
int len = getInputLength();

if (len <= MAX) {
memcpy(output, input, len);
}

Abstract
允许用户输入控制文件系统操作所用的路径会导致攻击者能够访问或修改其他受保护的文件。
Explanation
当满足以下两个条件时,就会产生 path manipulation 错误:

1.攻击者能够指定某一文件系统操作中所使用的路径。

2. 攻击者可以通过指定特定资源来获取某种权限,而这种权限在一般情况下是不可能获得的。

例如,在某一程序中,攻击者可以获得特定的权限,以重写指定的文件或是在其控制的配置环境下运行程序。
示例 1:以下代码使用来自于 HTTP 请求的输入来创建文件名。


...
*Get the report that is to be deleted
r_name = request->get_form_field( 'report_name' ).
CONCATENATE `C:\\users\\reports\\` r_name INTO dsn.
DELETE DATASET dsn.
...


如果攻击者提供类似“..\\..\\usr\\sap\\DVEBMGS00\\exe\\disp+work.exe”的文件夹名,应用程序会删除重要文件,导致 SAP 系统立即崩溃。

例 2:以下代码用于显示针对用户提供的任何日期的清单详细信息。


...
PARAMETERS: p_date TYPE string.

*Get the invoice file for the date provided
CALL FUNCTION 'FILE_GET_NAME'
EXPORTING
logical_filename = 'INVOICE'
parameter_1 = p_date
IMPORTING
file_name = v_file
EXCEPTIONS
file_not_found = 1
OTHERS = 2.
IF sy-subrc <> 0.
* Implement suitable error handling here
ENDIF.

OPEN DATASET v_file FOR INPUT IN TEXT MODE.

DO.
READ DATASET v_file INTO v_record.
IF SY-SUBRC NE 0.
EXIT.
ELSE.
WRITE: / v_record.
ENDIF.
ENDDO.
...


如果攻击者提供类似“..\\..\\usr\\sap\\sys\\profile\\default.pfl”的字符串,而不提供有效日期,应用程序将显示所有默认 SAP 应用程序服务器配置文件参数设置,这可能会导致更精确的攻击。

Abstract
允许用户输入控制文件系统操作所用的路径会导致攻击者能够访问或修改其他受保护的系统资源。
Explanation
当满足以下两个条件时,就会产生 path manipulation 错误:

1.攻击者能够指定某一文件系统操作中所使用的路径。

2. 攻击者可以通过指定特定资源来获取某种权限,而这种权限在一般情况下是不可能获得的。

例如,在某一程序中,攻击者可以获得特定的权限,以重写指定的文件或是在其控制的配置环境下运行程序。
示例 1:以下代码使用来自于 HTTP 请求的输入来创建一个文件名。程序员没有考虑到攻击者可能使用像“../../tomcat/conf/server.xml”一样的文件名,从而导致应用程序删除它自己的配置文件。


var params:Object = LoaderInfo(this.root.loaderInfo).parameters;
var rName:String = String(params["reportName"]);
var rFile:File = new File("/usr/local/apfr/reports/" + rName);
...
rFile.deleteFile();
示例 2:下面的代码使用来自于配置文件的输入来决定打开哪个文件,并写入“Debug”控制台或日志文件。如果程序以足够的权限运行,且恶意用户能够篡改配置文件,那么他们可以通过程序读取系统中以扩展名 .txt 结尾的任何文件。


var fs:FileStream = new FileStream();
fs.open(new File(String(configStream.readObject())+".txt"), FileMode.READ);
fs.readBytes(arr);
trace(arr);

Abstract
允许用户输入控制文件系统操作所用的路径会导致攻击者能够访问或修改其他受保护的系统资源。
Explanation
当满足以下两个条件时,就会产生 path manipulation 错误:

1.攻击者能够指定某一文件系统操作中所使用的路径。

2.攻击者可以通过指定特定资源来获取某种权限,而这种权限在一般情况下是不可能获得的。

示例 1:以下 Visualforce 操作方法使用用户输入来访问静态资源。


public class MyController {

Abstract
允许用户输入控制文件系统操作所用的路径会导致攻击者能够访问或修改其他受保护的系统资源。
Explanation
当满足以下两个条件时,就会产生 path manipulation 错误:

1.攻击者能够指定某一文件系统操作中所使用的路径。

2. 攻击者可以通过指定特定资源来获取某种权限,而这种权限在一般情况下是不可能获得的。

例如,在某一程序中,攻击者可以获得特定的权限,以重写指定的文件或是在其控制的配置环境下运行程序。
示例 1:以下代码利用来自 CGI 请求的输入生成一个文件名。程序员没有考虑到攻击者可能使用像“../../apache/conf/httpd.conf”一样的文件名,从而导致应用程序删除特定的配置文件。


char* rName = getenv("reportName");
...
unlink(rName);
示例 2:以下代码使用来自于命令行的输入来决定该打开哪个文件,并返回到用户。如果程序以足够的权限运行,并且恶意用户能够创建指向文件的软链接,那么他们可以使用程序来读取系统中任何文件的开始部分。


ifstream ifs(argv[0]);
string s;
ifs >> s;
cout << s;

Abstract
允许用户输入控制文件操作中所用的文件资源名称会导致攻击者能够访问或修改并非是应用程序最初设计的数据集。
Explanation
当满足以下两个条件时,CICS 中就会产生 path manipulation 错误:

1.攻击者可以指定 CICS 文件操作中使用的文件资源 (FCT) 名称。

2.通过指定资源,攻击者可以获取未经授权的访问权限。

例如,在某一程序中,攻击者能够读取或写入针对应用程序通常不会访问的 CICS 区域配置的数据。
示例 1:以下代码使用来自 HTML 表单的输入来更新或有可能删除文件中的记录。


...
EXEC CICS
WEB READ
FORMFIELD(FILE)
VALUE(FILENAME)
...
END-EXEC.

EXEC CICS
READ
FILE(FILENAME)
INTO(RECORD)
RIDFLD(ACCTNO)
UPDATE
...
END-EXEC.

Abstract
如果允许用户输入控制文件系统操作所用的路径,攻击者将可以在系统上对文件进行随意覆盖。
Explanation
示例 1:以下示例以不安全的方式删除了文件。


final server = await HttpServer.bind('localhost', 18081);
server.listen((request) async {
final headers = request.headers;
final path = headers.value('path');
File(path!).delete();
}


Example 1 中,在对文件执行删除功能之前未验证 headers.value('path')

Abstract
允许用户输入控制文件系统操作所用的路径会导致攻击者能够访问或修改其他受保护的系统资源。
Explanation
当满足以下两个条件时,就会产生 path manipulation 错误:

1.攻击者能够指定某一文件系统操作中所使用的路径。

2.攻击者可以通过指定特定资源来获取某种权限,而这种权限在一般情况下是不可能获得的。

例如,在某一程序中,攻击者可以获得特定的权限,以重写指定的文件或是在其控制的配置环境下运行程序。
示例 1:下面的代码使用来自于 HTTP 请求的输入来创建一个文件名。程序员没有考虑到攻击者可能使用像“../../tomcat/conf/server.xml”一样的文件名,从而导致应用程序删除它自己的配置文件。


rName := "/usr/local/apfr/reports/" + req.FormValue("fName")

rFile, err := os.OpenFile(rName, os.O_RDWR|os.O_CREATE, 0755)

defer os.Remove(rName);
defer rFile.Close()
...

示例 2:下面的代码使用来自于配置文件的输入来决定打开哪个文件,并返回给用户。如果程序以足够的权限运行,且恶意用户能够篡改配置文件,那么他们可以通过程序读取系统中以扩展名 .txt 结尾的任何文件。


...
config := ReadConfigFile()

filename := config.fName + ".txt";
data, err := ioutil.ReadFile(filename)

...

fmt.Println(string(data))

amt = fis.read(arr);
out.println(arr);


有些人认为在移动环境中,典型的漏洞(如 path manipulation)是无意义的 -- 为什么用户要攻击自己?但是,谨记移动平台的本质是从各种来源下载并在相同设备上运行的应用程序。恶意软件在银行应用程序附近运行的可能性很高,它们会强制扩展移动应用程序的攻击面(包括跨进程通信)。

示例 3:以下代码会调整Example 1 以适应 Android 平台。


...
String rName = this.getIntent().getExtras().getString("reportName");
File rFile = getBaseContext().getFileStreamPath(rName);
...
rFile.delete();

Abstract
允许用户输入控制文件系统操作所用的路径会导致攻击者能够访问或修改其他受保护的系统资源。
Explanation
当满足以下两个条件时,就会产生 path manipulation 错误:

1.攻击者能够指定某一文件系统操作中所使用的路径。

2. 攻击者可以通过指定特定资源来获取某种权限,而这种权限在一般情况下是不可能获得的。

例如,在某一程序中,攻击者可以获得特定的权限,以重写指定的文件或是在其控制的配置环境下运行程序。
示例 1:以下代码使用来自于 HTTP 请求的输入来创建一个文件名。程序员没有考虑到攻击者可能使用像“../../tomcat/conf/server.xml”一样的文件名,从而导致应用程序删除它自己的配置文件。


...
var reportNameParam = "reportName=";
var reportIndex = document.indexOf(reportNameParam);
if (reportIndex < 0) return;
var rName = document.URL.substring(reportIndex+reportNameParam.length);
window.requestFileSystem(window.TEMPORARY, 1024*1024, function(fs) {
fs.root.getFile('/usr/local/apfr/reports/' + rName, {create: false}, function(fileEntry) {
fileEntry.remove(function() {
console.log('File removed.');
}, errorHandler);

}, errorHandler);
}, errorHandler);
示例 2:以下代码使用来自于本地存储的输入来决定该打开哪个文件,并返回到用户。如果恶意用户能够更改本地存储的内容,就可以使用该程序来读取系统中扩展名为 .txt 的任何文件。


...
var filename = localStorage.sub + '.txt';
function oninit(fs) {
fs.root.getFile(filename, {}, function(fileEntry) {
fileEntry.file(function(file) {
var reader = new FileReader();
reader.onloadend = function(e) {
var txtArea = document.createElement('textarea');
txtArea.value = this.result;
document.body.appendChild(txtArea);
};
reader.readAsText(file);
}, errorHandler);
}, errorHandler);
}

window.requestFileSystem(window.TEMPORARY, 1024*1024, oninit, errorHandler);

允许用户输入控制文件系统操作所用的路径会导致攻击者能够访问或修改其他受保护的系统资源。

当满足以下两个条件时,就会产生 path manipulation 错误:

2.攻击者可以通过指定特定资源来获取某种权限,而这种权限在一般情况下是不可能获得的。

例如,在某一程序中,攻击者可以获得特定的权限,以重写指定的文件或是在其控制的配置环境下运行程序。
示例 1:下面的代码使用来自于 HTTP 请求的输入来创建一个文件名。程序员没有考虑到攻击者可能使用像“../../tomcat/conf/server.xml”一样的文件名,从而导致应用程序删除它自己的配置文件。


val rName: String = request.getParameter("reportName")
val rFile = File("/usr/local/apfr/reports/$rName")
...
rFile.delete()
示例 2:下面的代码使用来自于配置文件的输入来决定打开哪个文件,并返回给用户。如果程序以足够的权限运行,且恶意用户能够篡改配置文件,那么他们可以通过程序读取系统中以扩展名 .txt 结尾的任何文件。


fis = FileInputStream(cfg.getProperty("sub").toString() + ".txt")
amt = fis.read(arr)
out.println(arr)


有些人认为在移动环境中,典型的漏洞(如 path manipulation)是无意义的 -- 为什么用户要攻击自己?但是,谨记移动平台的本质是从各种来源下载并在相同设备上运行的应用程序。恶意软件在银行应用程序附近运行的可能性很高,它们会强制扩展移动应用程序的攻击面(包括跨进程通信)。

示例 3:以下代码会调整Example 1 以适应 Android 平台。


...
val rName: String = getIntent().getExtras().getString("reportName")
val rFile: File = getBaseContext().getFileStreamPath(rName)
...
rFile.delete()
...

Abstract
允许用户输入控制文件系统操作所用的路径会导致攻击者能够访问或修改其他受保护的系统资源。
Explanation
当满足以下两个条件时,就会产生 path manipulation 错误:

1.攻击者能够指定某一文件系统操作中所使用的路径。

2. 攻击者可以通过指定特定资源来获取某种权限,而这种权限在一般情况下是不可能获得的。

例如,在某一程序中,攻击者可以获得特定的权限,以重写指定的文件或是在其控制的配置环境下运行程序。
示例 1:以下代码使用来自于 HTTP 请求的输入来创建一个文件名。程序员没有考虑到攻击者可能使用像“../../tomcat/conf/server.xml”一样的文件名,从而导致应用程序删除它自己的配置文件。


$rName = $_GET['reportName'];
$rFile = fopen("/usr/local/apfr/reports/" . rName,"a+");
...
unlink($rFile);
示例 2:以下代码使用来自于配置文件的输入来决定打开哪个文件,并返回给用户。如果程序以足够的权限运行,且恶意用户能够篡改配置文件,那么他们可以通过程序读取系统中以扩展名 .txt 结尾的任何文件。


...
$filename = $CONFIG_TXT['sub'] . ".txt";
$handle = fopen($filename,"r");
$amt = fread($handle, filesize($filename));
echo $amt;

desc.dataflow.scala.path_manipulation
Abstract
攻击者能够控制文件系统路径参数,借此访问或修改原本受保护的文件。
Explanation
当满足以下两个条件时,就会产生 path manipulation 错误:

1.攻击者能够指定某一文件系统操作中所使用的路径。

2. 攻击者可以通过指定特定资源来获取某种权限,而这种权限在一般情况下是不可能获得的。

例如,在某一程序中,攻击者可以获得特定的权限,以重写指定的文件或是在其控制的配置环境下运行程序。
示例 1:以下代码使用用户的输入创建文件路径。程序员没有考虑到攻击者可能使用其他文件名,从而导致应用程序删除非指定的文件。


func testFileManager() -> NSData {
let filePath : String = "/Documents/\(fileName.text)"
let fm : NSFileManager = NSFileManager.defaultManager()
return fm.contentsAtPath(filePath)
}

Abstract
允许用户输入控制文件系统操作所用的路径会导致攻击者能够访问或修改其他受保护的系统资源。
Explanation
当满足以下两个条件时,就会产生 path manipulation 错误:

1.攻击者能够指定某一文件系统操作中所使用的路径。

2. 攻击者可以通过指定特定资源来获取某种权限,而这种权限在一般情况下是不可能获得的。

例如,在某一程序中,攻击者可以获得特定的权限,以重写指定的文件或是在其控制的配置环境下运行程序。
示例 1:以下代码使用来自于 HTTP 请求的输入来创建一个文件名。程序员没有考虑到攻击者可能使用像“..\conf\server.xml”一样的文件名,从而导致应用程序删除它自己的配置文件。


Dim rName As String
Dim fso As New FileSystemObject
Dim rFile as File
Set rName = Request.Form("reportName")
Set rFile = fso.GetFile("C:\reports\" & rName)
...
fso.DeleteFile("C:\reports\" & rName)
...
示例 2:以下代码使用来自于配置文件的输入来决定打开哪个文件,并返回给用户。如果程序以足够的权限运行,且恶意用户能够篡改配置文件,那么他们可以通过程序读取系统中以扩展名 .txt 结尾的任何文件。


Dim fileName As String
Dim tsContent As String
Dim ts As TextStream
Dim fso As New FileSystemObject

fileName = GetPrivateProfileString("MyApp", "sub", _
"", value, Len(value), _
App.Path & "\" & "Config.ini")
...
Set ts = fso.OpenTextFile(fileName,1)
tsContent = ts.ReadAll
Response.Write tsContent
...

Abstract
允许用户输入控制文件系统操作所用的路径会导致攻击者能够访问或修改其他受保护的系统资源。
Explanation
Path.Combine 将多个文件路径作为参数。 连接它们可获得一条完整路径,通常后面跟随该文件的 read()write() 调用。 根据第一个参数还是剩余参数是绝对路径,文档介绍了几种不同情况。 如果第二个或剩余参数为绝对路径,则 Path.Combine() 将返回该绝对路径。 以前的参数将忽略。 这里的含义对于具有类似下面示例代码的应用程序而言非常重要。


示例 1: 以下代码以非安全方式下载具有用户控制路径元素的文件:


// Called with user-controlled data
public static bytes[] getFile(String filename)
{
String imageDir = "\\FILESHARE\images\";
filepath = Path.Combine(imageDir, filename);
return File.ReadAllBytes(filepath);
}


通过提供绝对路径(例如 C:\\inetpub\wwwroot\web.config),攻击者可以控制应用程序返回哪个文件。

Abstract
如果允许用户输入控制文件系统操作所用的路径,攻击者将可以在系统上对文件进行随意覆盖。
Explanation
Path Manipulation:在打开和扩展 ZIP 文件但未检查 ZIP 条目的文件路径时,会出现 ZIP Entry Overwrite 错误。

示例 1:以下示例从 ZIP 文件中提取文件并以非安全方式将其写入磁盘。


...

" Add Binary File to
CALL METHOD lr_abap_zip->add
EXPORTING
name = p_ifile
content = lv_bufferx.

" Read Binary File to
CALL METHOD lr_abap_zip->get
EXPORTING
name = p_ifile
IMPORTING
content = lv_bufferx2.

...


Example 1 中,在对此条目中的数据执行读取/写入函数之前未验证 p_ifile。如果 ZIP 文件最初放置在基于 Unix 的计算机的 "/tmp/" 目录中,并且 ZIP 条目为 "../etc/hosts",而应用程序在必要的权限下运行,则它将覆盖系统的 hosts 文件,从而会使该计算机的流量进入攻击者所需的任何位置,例如返回至攻击者的计算机。

Abstract
允许用户输入控制文件系统操作中使用的路径会导致攻击者能够随意覆盖系统上的文件。
Explanation
Path Manipulation:在打开和扩展 Zip 文件但未检查 Zip 条目的文件路径时,将会出现 Zip Entry Overwrite 错误。

示例 1:以下示例从 Zip 文件中提取文件并以不安全的方式将其写入磁盘。


public static void UnzipFile(ZipArchive archive, string destDirectory)
{
foreach (var entry in archive.Entries)
{
string file = entry.FullName;
if (!string.IsNullOrEmpty(file))
{
string destFileName = Path.Combine(destDirectory, file);
entry.ExtractToFile(destFileName, true);

}
}
}


Example 1 中,在对此条目中的数据执行读取/写入操作之前不会对 entry.FullName 进行验证。如果此 Zip 文件最初放置在“C:\TEMP”目录中,并且某个 Zip 条目名称包含“..\ segments”,而应用程序在所需的权限下运行,则它可以随意覆盖系统文件。

Abstract
如果允许用户输入控制 file system 操作所用的路径,攻击者将可以在系统上对文件进行随意覆盖。
Explanation
Path Manipulation:在打开和扩展 Zip 文件但未检查 Zip 条目的文件路径时,将会出现 Zip Entry Overwrite 错误。

示例 1:以下示例从 Zip 文件中提取文件并以不安全的方式将其写入磁盘。


private static final int BUFSIZE = 512;
private static final int TOOBIG = 0x640000;
...
public final void unzip(String filename) throws IOException {
FileInputStream fis = new FileInputStream(filename);
ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis));
ZipEntry zipEntry = null;

int numOfEntries = 0;
long total = 0;

try {
while ((zipEntry = zis.getNextEntry()) != null) {
byte data[] = new byte[BUFSIZE];
int count = 0;
String outFileName = zipEntry.getName();
if (zipEntry.isDirectory()){
new File(outFileName).mkdir(); //create the new directory
continue;
}
FileOutputStream outFile = new FileOutputStream(outFileName);
BufferedOutputStream dest = new BufferedOutputStream(outFile, BUFSIZE);
//read data from Zip, but do not read huge entries
while (total + BUFSIZE <= TOOBIG && (count = zis.read(data, 0, BUFSIZE)) != -1) {
dest.write(data, 0, count);
total += count;
}
...
}
} finally{
zis.close();
}
}
...


Example 1 中,在对此条目中的数据执行读取/写入函数之前未验证 zipEntry.getName()。如果 Zip 文件最初放置在基于 Unix 的计算机的“/tmp/”目录中,并且 Zip 条目为“../etc/hosts”,而应用程序在所需的权限下运行,则它将覆盖系统 hosts 文件。从而可能会使该计算机的流量进入攻击者所需的任何位置,例如返回至攻击者的计算机。

Abstract
允许用户输入控制文件系统操作中使用的路径会导致攻击者能够随意覆盖系统上的文件。
Explanation
Path Manipulation:在打开和扩展 Zip 文件但未检查 Zip 条目的文件路径时,将会出现 Zip Entry Overwrite 错误。

示例 1:以下示例从 Zip 文件中提取文件并以不安全的方式将其写入磁盘。


ZZArchive* archive = [ZZArchive archiveWithURL:[NSURL fileURLWithPath: zipPath] error:&error];
for (ZZArchiveEntry* entry in archive.entries) {
NSString *fullPath = [NSString stringWithFormat: @"%@/%@", destPath, [entry fileName]];
[[entry newDataWithError:nil] writeToFile:newFullPath atomically:YES];
}


Example 1 中,在对此条目中的数据执行读取/写入函数之前未验证 entry.fileName。如果 Zip 文件最初放置在 iOS 应用程序的“Documents/hot_patches”目录中,并且 Zip 条目为“../js/page.js”,则它将覆盖 page.js 文件,从而可能会使攻击者能够注入可能导致代码执行的恶意代码。

desc.dataflow.python.path_manipulation_zip_entry_overwrite
Abstract
允许用户输入控制文件系统操作中使用的路径会导致攻击者能够随意覆盖系统上的文件。
Explanation
Path Manipulation:在打开和扩展 Zip 文件但未检查 Zip 条目的文件路径时,将会出现 Zip Entry Overwrite 错误。

示例 1:以下示例从 Zip 文件中提取文件并以不安全的方式将其写入磁盘。


import better.files._

...

val zipPath: File = getUntrustedZip()
val destinationPath = file"out/dest"
zipPath.unzipTo(destination = destinationPath)
示例 2:以下示例从 Zip 文件中提取文件并以不安全的方式将其写入磁盘。


import better.files._

...

val zipPath: File = getUntrustedZip()
val destinationPath = file"out/dest"
zipPath.newZipInputStream.mapEntries( (entry : ZipEntry) => {
entry.extractTo(destinationPath, new FileInputStream(entry.getName))
})


Example 2 中,在对此条目中的数据执行读取/写入函数之前未验证 entry.getName。如果 Zip 文件最初放置在基于 Unix 的计算机的“/tmp/”目录中,并且 Zip 条目为“../etc/hosts”,而应用程序在所需的权限下运行,则它将覆盖系统 hosts 文件。从而可能会使该计算机的流量进入攻击者所需的任何位置,例如返回至攻击者的计算机。

Abstract
允许用户输入控制文件系统操作中使用的路径会导致攻击者能够随意覆盖系统上的文件。
Explanation
Path Manipulation:在打开和扩展 Zip 文件但未检查 Zip 条目的文件路径时,将会出现 Zip Entry Overwrite 错误。

示例 1:以下示例从 Zip 文件中提取文件并以不安全的方式将其写入磁盘。


let archive = try ZZArchive.init(url: URL(fileURLWithPath: zipPath))

for entry in archive.entries {
let fullPath = URL(fileURLWithPath: destPath + "/" + entry.fileName)
try entry.newData().write(to: fullPath)
}


Example 1 中,在对此条目中的数据执行读取/写入函数之前未验证 entry.fileName。如果 Zip 文件最初放置在 iOS 应用程序的“Documents/hot_patches”目录中,并且 Zip 条目为“../js/page.js”,则它将覆盖 page.js 文件,从而可能会使攻击者能够注入可能导致代码执行的恶意代码。

Abstract
此程序会调用可覆盖变量的函数,这可能会为攻击者打开方便之门。
Explanation
对于可覆盖已初始化的变量的函数,攻击者能够通过它影响依赖被覆盖变量的代码的执行情况。
可以覆盖变量。

例 1:如果攻击者为下面这段 ColdFusion 代码中的 varName 提供恶意值,则对 SetVariable() 的调用可能会覆盖所有任意变量,包括 #first#。在这种情况下,如果包含 JavaScript 的恶意值覆盖 #first#,则该程序会很容易受到 cross-site scripting 攻击。


<cfset first = "User">
<cfscript>
SetVariable(url.varName, url.varValue);
</cfscript>
<cfoutput>
#first#
</cfoutput>

Abstract
如果使用来自不可信数据源的输入构造动态 NSPredicate,则可能会允许攻击者修改语句的含义。
Explanation
NSPredicate 实例指定应如何从来源(如 CoreData 永久性存储系统、数组和字典)获取或过滤集合。其查询语言提供与 SQL 类似的表达性语言,以定义搜索集合时所应依据的逻辑条件。

能够影响谓词的攻击者可能会更改其含义,以便泄漏数据、绕过安全控制或模拟其他用户等。

示例 1:以下示例显示如何使用 NSPredicate 作为身份验证因素来访问应用程序所存储的某些数据。由于用户可以提供任意 PIN 值,因此他们可以使用通配符 (*) 绕过 PIN 保护。


NSString *pin = [self getPinFromUser];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"pin LIKE %@", pin];

Abstract
将程序控制转移到不可信赖的应用程序、事务或是不可信赖的环境中,会导致应用程序以攻击者的名义执行恶意代码。
Explanation
Process control 漏洞主要表现为以下两种形式:

— 攻击者能够篡改即将调用的程序的名称或事务的代码:攻击者直接地控制应用程序的名称和事务代码。

— 攻击者能够篡改调用程序或事务的环境:攻击者能够间接控制调用的程序或事务可用的通信区域。

在这种情况下,我们着重关注第一种情况,即攻击者有可能控制调用的程序名称或事务代码。这种类型的 Process Control 漏洞会在以下情况下出现:

1. 数据从不可信赖的数据源进入应用程序。



2. 数据作为代表调用的程序名称或事务代码的一个字符串或部分字符串使用。



3. 通过在调用的程序或事务中执行代码,应用程序授予攻击者在一般情况下无法获得的权限或能力。

示例 1:以下代码摘自具有特别权限的系统实用程序,它通过从 HTTP 请求中读取值来确定要调用的事务代码。


...
tid = request->get_form_field( 'tid' ).

CALL TRANSACTION tid USING bdcdata MODE 'N'
MESSAGES INTO messtab.
...


以下摘录的代码使得攻击者能够调用任何事务,并有可能使用提升的应用程序权限来执行任意代码。因为程序不会检验从 HTTP 请求读取的值,所以如果攻击者可以控制这些值,他们就能欺骗应用程序去运行恶意代码,从而取得系统控制权。

Abstract
从一个不可信赖的数据源或在不可信赖的环境中加载库或可执行文件,会导致应用程序以攻击者的名义执行恶意命令。
Explanation
Process control 漏洞主要表现为以下两种形式:

- 攻击者可以篡改程序所加载的库或可执行文件的名称:攻击者直接控制库或可执行文件所使用的名称。

- 攻击者可以篡改加载库或可执行文件的环境:攻击者间接控制库或可执行文件名称的含义。

在这种情况下,我们着重关注第一种情况,即攻击者有可能控制加载的库的名称。这种类型的 Process Control 漏洞会在以下情况下出现:

1. 数据从不可信赖的数据源进入应用程序。



2. 数据将用作表示应用程序所加载的库或可执行文件的字符串或该字符串的一部分。



3. 通过在库或可执行文件中执行代码,应用程序授予攻击者在其他情况下无法获得的特权或能力。

示例 1:特权系统实用程序中的以下代码使用应用程序配置属性 APPHOME,然后根据指定目录的相对路径加载本地库。


...
string lib = ConfigurationManager.AppSettings["APPHOME"];
Environment.ExitCode = AppDomain.CurrentDomain.ExecuteAssembly(lib);
...


这段代码允许攻击者加载库或可执行文件,并通过修改应用程序配置属性 APPHOME 以指向包含恶意版本 LIBNAME 的不同路径,从而使用更高的应用程序权限来执行任意代码。由于程序不会验证从环境中读取的值,因此如果攻击者能够控制系统属性 APPHOME 的值,他们就能欺骗应用程序去运行恶意代码,从而控制系统。

Abstract
从一个不可信赖的数据源或不可信赖的环境中加载库,会导致程序以攻击者的名义执行恶意代码。
Explanation
Process control 漏洞主要表现为以下两种形式:

- 攻击者能够篡改程序执行的库:攻击者直接控制了库的名称。

— 攻击者可以篡改库加载的环境:攻击者间接控制库名称的含义。

在这种情况下,我们着重关注第一种情况,即攻击者有可能控制加载的库的名称。这种类型的 Process Control 漏洞会在以下情况下出现:

1. 数据从不可信赖的数据源进入应用程序。

2. 数据作为字符串的一部分,代表一个由应用程序加载的库名。

3. 通过在库中执行代码,应用程序授予攻击者在一般情况下无法获得的权限或能力。

示例 1:以下代码来自于一个特权应用程序,使用注册表项来决定安装的目录,然后用基于指定目录的相对路径,加载一个库文件。


...
RegQueryValueEx(hkey, "APPHOME",
0, 0, (BYTE*)home, &size);
char* lib=(char*)malloc(strlen(home)+strlen(INITLIB));
if (lib) {
strcpy(lib,home);
strcat(lib,INITCMD);
LoadLibrary(lib);
}
...


在这个例子中,代码通过篡改注册表主键来指定一个包含 INITLIB 恶意版本的其他路径,进而允许攻击者加载一个任意库,以提高的应用程序权限去执行库中的任意代码。因为程序不会校验从环境中读取的值,如果攻击者能够控制 APPHOME 的值,就能欺骗应用程序去运行恶意的代码。

示例 2:以下代码来自于一个基于 web 的管理实用程序,它允许用户访问一个接口,通过这个接口更新用户在系统上的配置文件。该实用程序使用一个名为 liberty.dll 的库,该库通常可在一个标准的系统目录中找到。


LoadLibrary("liberty.dll");


但是,程序并没有指定 liberty.dll 的绝对路径。在搜索顺序上,如果攻击者将一个名为 liberty.dll 的恶意库放在原本想要的库的前面,并且攻击者能够让程序在他们的环境(而不是 web 服务器环境)中运行,那么应用程序就会加载该恶意库,而不是原本想要的可信赖的库。由于这种类型的应用程序会以提高了的权限运行,因此攻击者的 liberty.dll 中的内容也将以提高的权限运行,这可能会使攻击者完全控制系统。

这种类型的攻击可能是由于在没有指明绝对路径的情况下,LoadLibrary() 所使用的搜索顺序造成的。如果当前目录比系统目录先搜索到,就像现在大多数最新的 Windows 版本,那么如果攻击者可在本地执行程序,这种类型的攻击就会变得十分简单。搜索顺序取决于操作系统的版本,在比较新的操作系统中,这一顺序由注册表主键控制:


HKLM\System\CurrentControlSet\Control\Session Manager\SafeDllSearchMode


该键值没有在 Windows 2000/NT 及 Windows Me/98/95 中定义。

在存在此键的操作系统上,LoadLibrary() 按以下方式运行:
如果 SafeDllSearchMode 为 1,搜索顺序如下所示:
(这是 Windows XP-SP1 及更高版本,包括 Windows Server 2003 的默认设置。)
1. 应用程序被加载的目录。
2. 系统目录。
3. 16 位系统目录(如果存在)。
4. Windows 目录。
5. 当前目录。
6. 在 PATH 环境变量中列出来的目录。
如果 SafeDllSearchMode 为 0,搜索顺序如下所示:
1. 应用程序被加载的目录。
2. 当前目录。
3. 系统目录。
4. 16 位系统目录(如果存在)。
5. Windows 目录。
6. 在 PATH 环境变量中列出来的目录。

Abstract
将程序控制转移到不可信赖的应用程序或是不可信赖的环境中会导致应用程序以攻击者的名义执行恶意代码。
Explanation
Process control 漏洞主要表现为以下两种形式:

— 攻击者能够篡改要调用的程序的名称:攻击者直接地控制应用程序的名称。

— 攻击者能够篡改调用程序的环境:攻击者能够间接控制调用的程序可用的通信区域。

在这种情况下,我们着重关注第一种情况,即攻击者有可能控制调用的程序名称。这种形式的进程控制漏洞在以下情况下发生:

1. 数据从不可信赖的数据源进入应用程序。



2.数据用作表示调用的程序的整个字符串或一部分,或者确定对调用程序的环境的某些控制。



3. 通过在调用的程序中执行代码,应用程序授予攻击者在一般情况下无法获得的权限或能力。

示例 1:以下来自具有特别权限的系统实用程序的代码从终端中读取值,以确定转移控制的目标程序的名称。


...
ACCEPT PROGNAME.
EXEC CICS
LINK PROGRAM(PROGNAME)
COMMAREA(COMA)
LENGTH(LENA)
DATALENGTH(LENI)
SYSID('CONX')
END-EXEC.
...


此代码使攻击者能够将控制转移至一个程序,并有可能使用提升的应用程序权限来执行任意代码。因为程序不会检验从终端读取的值,所以如果攻击者可以控制这些值,他们就能欺骗应用程序,从而执行恶意代码并取得对系统的控制。

Abstract
从一个不可信赖的数据源或是不可信赖的环境中加载库,会导致应用程序以攻击者的名义执行恶意代码。
Explanation
Process control 漏洞主要表现为以下两种形式:

— 攻击者可以篡改程序加载的库的名称:攻击者直接地控制库所使用的名称。

— 攻击者可以篡改库加载的环境:攻击者间接控制库名称的含义。

在这种情况下,我们着重关注第一种情况,即攻击者有可能控制加载的库的名称。这种类型的 Process Control 漏洞会在以下情况下出现:

1. 数据从不可信赖的数据源进入应用程序。



2. 数据作为代表应用程序所加载的库的一个或部分字符串使用。



3. 通过在库中执行代码,应用程序授予攻击者在一般情况下无法获得的权限或能力。

例 1:以下代码来自于一个具有特别权限的系统实用程序,使用系统属性 APPHOME 来确定系统的安装目录,然后用基于指定目录的相对路径加载本地库。


...
String home = System.getProperty("APPHOME");
String lib = home + LIBNAME;
java.lang.Runtime.getRuntime().load(lib);
...


这段代码允许攻击者加载库,并通过修改系统属性 APPHOME,指向一个包含恶意版本 LIBNAME 的不同路径,从而使用较高的应用程序权限去执行任意代码。由于程序不会验证从环境中读取的值,所以如果攻击者能够控制系统属性 APPHOME 的值,他们就能欺骗应用程序去运行恶意代码从而取得系统控制权。

例 2:以下代码使用 System.loadLibrary() 从名为 library.dll 的本地库加载代码,它通常可以在标准的系统目录中找到。


...
System.loadLibrary("library.dll");
...


这里的问题是,对于要加载的库来说,System.loadLibrary() 只会接受库的名称,而不接受库的路径。根据 Java 1.4.2 API 文档,这个函数会进行如下操作 [1]:

可以从库文件能够正常获取的本地 file system 中加载含有本地代码的文件。这一过程的具体操作需在特定的条件下执行。从库名称到某一个特定文件名的映射是在特定的系统方式下完成的。

在搜索顺序方面,如果攻击者将一份恶意的 library.dll 放在高于应用程序需要加载的文件的位置,那么应用程序就会加载该恶意代码,而不会选择加载最初需要的文件。由于应用程序的这一特性,它会以较高的权限运行,这就意味着攻击者的 library.dll 内容将以较高的权限运行,从而可能导致攻击者完全控制整个系统。

2. 数据作为代表应用程序所加载的库的一个或部分字符串使用。



3. 通过在库中执行代码,应用程序授予攻击者在一般情况下无法获得的权限或能力。

示例 1:以下代码使用 Express 当前未记录的“功能”动态加载库文件。然后,Node.js 将继续在其正则库加载路径中搜索包含此库的文件或目录[1]。


var express = require('express');
var app = express();

app.get('/', function(req, res, next) {
res.render('tutorial/' + req.params.page);
});


Express 中,传递到 Response.render() 的页面将加载先前未知的扩展库。这对于“foo.pug”等输入来说通常没有问题,因为这意味着加载 pug 库,该库是广为人知的模板引擎。但是,如果攻击者可以控制页面并进而控制扩展,那么他们便可以选择加载 Node.js 模块加载路径内的任何库。因为程序不会验证从 URL 参数接收的信息,所以攻击者可能会欺骗应用程序,去执行恶意代码并取得对系统的控制。

Abstract
从一个不可信赖的数据源或是不可信赖的环境中加载库,会导致应用程序以攻击者的名义执行恶意代码。
Explanation
Process control 漏洞主要表现为以下两种形式:

— 攻击者可以篡改程序加载的库的名称:攻击者直接地控制库所使用的名称。

— 攻击者可以篡改库加载的环境:攻击者间接控制库名称的含义。

在这种情况下,我们着重关注第一种情况,即攻击者有可能控制加载的库的名称。这种类型的 Process Control 漏洞会在以下情况下出现:

1. 数据从不可信赖的数据源进入应用程序。



2. 数据作为代表应用程序所加载的库的一个或部分字符串使用。



3. 通过在库中执行代码,应用程序授予攻击者在一般情况下无法获得的权限或能力。

例 1:以下代码来自于一个具有特别权限的系统实用程序,使用系统属性 APPHOME 来确定系统的安装目录,然后用基于指定目录的相对路径加载本地库。


...
$home = getenv("APPHOME");
$lib = $home + $LIBNAME;
dl($lib);
...


这段代码允许攻击者加载库,并通过修改系统属性 APPHOME,指向一个包含恶意版本 LIBNAME 的不同路径,从而使用较高的应用程序权限去执行任意代码。由于程序不会验证从环境中读取的值,所以如果攻击者能够控制系统属性 APPHOME 的值,他们就能欺骗应用程序去运行恶意代码从而取得系统控制权。

例 2:下列代码使用 dl() 来从名为 sockets.dll 的库加载代码,此库可从多个位置加载,具体取决于您的安装和配置。


...
dl("sockets");
...


这里的问题是,对于要加载的库来说,dl() 只会接受库的名称,而不接受库的路径。

在搜索顺序方面,如果攻击者将一份恶意的 sockets.dll 放在高于应用程序需要加载的文件的位置,那么应用程序就会加载该恶意代码,而不会选择加载最初需要的文件。由于应用程序的这一特性,它会以较高的权限运行,这就意味着攻击者的 sockets.dll 内容将以较高的权限运行,从而可能导致攻击者完全控制整个系统。

Abstract
从一个不可信赖的数据源或是不可信赖的环境中加载库,会导致应用程序以攻击者的名义执行恶意代码。在 Ruby 中,存在可能会同时发生 Process Control 和 Command Injection 攻击的共同位置。
Explanation
在 Ruby 中,当正在执行某个命令时通常会发生 Process Control 攻击,这使得会发生两个不同的攻击:

1. Process Control
Process Control 漏洞表现为以下两种形式:

— 攻击者可以篡改程序加载的库的名称:攻击者直接地控制库所使用的名称。

— 攻击者可以篡改库加载的环境:攻击者间接控制库名称的含义。

在这种情况下,我们着重关注第二种情况,即攻击者有可能通过程序加载指定库的恶意版本,以此来控制环境。

1. 攻击者为应用程序提供一个恶意的库。

2. 应用程序因为未指定一个绝对的路径,或未验证加载的文件而加载了恶意的库。

3. 通过在库中执行代码,应用程序授予攻击者在一般情况下无法获得的权限或能力。

请注意,当运行外部程序时,在 Windows 平台上可能会发生 Process Control 攻击,因为用于运行命令的 shell 是通过 RUBYSHELL 或 COMSPEC 环境变量选择的。如果攻击者能够在当前环境中修改这两个环境变量之一,这意味这两个环境变量所指的程序将使用权限或者运行的 Ruby 程序运行。

2. Command Injection
Command Injection 漏洞主要表现为以下两种形式:

- 攻击者能够篡改程序执行的命令:攻击者直接控制了所执行的命令。

- 攻击者能够篡改命令的执行环境:攻击者间接地控制了所执行的命令。

在这种情况下,我们着重关注第二种情况,即攻击者有可能通过篡改一个环境变量或预先在搜索路径中输入可执行的恶意内容,进而更改命令所代表的原始含义。这种类型的 Command Injection 漏洞会在以下情况下出现:

1. 攻击者篡改某一应用程序的环境。

2. 应用程序在没有指明绝对路径,或者没有检验所执行的二进制代码的情况下就执行命令。

3. 通过命令的执行,应用程序会授予攻击者一种原本不该拥有的特权或能力。

示例 1:以下代码通过运行 Kernel.system() 来运行称为 program.exe 的可执行文件,通常在标准系统目录中可找到该可执行文件。


...
system("program.exe")
...


这里的问题是双重的:
1. 在 Windows 平台上,Kernel.system() 通过 shell 执行程序。如果攻击者可以操纵 RUBYSHELLCOMSPEC 环境变量,这两个环境变量就能够指向恶意的可执行文件,通过为 Kernel.system() 指定的命令将会调用该可执行文件。由于应用程序自身的特性,它需要特定的权限执行系统操作,这意味着攻击者会利用这些权限执行自己的 program.exe,从而可能导致攻击者完全控制这个系统。
2. 这种情况下在所有平台上,问题在于,程序没有指定一个绝对的路径,并且在执行 Kernel.system() 调用之前未能清理其环境。如果攻击者能够篡改 $PATH 变量,使其指向一个名为 program.exe 的恶意二进制代码,然后在指定环境中运行应用程序,那么应用程序就会加载该恶意二进制代码,并以此替代原本期望的代码。由于应用程序自身的特性,它需要特定的权限执行系统操作,这意味着攻击者会利用这些权限执行自己的 program.exe,从而可能导致攻击者完全控制这个系统。

Abstract
将未经验证的数据发送到 AI 模型中的系统提示会允许攻击者操纵输出或执行未经授权的操作,从而损害系统完整性和数据安全性。
Explanation
在 AI 应用程序中,系统提示提供指导 AI 响应的预处理指令或上下文。攻击者可以精心设计输入,当按照系统提示嵌入时,会更改 AI 模型的行为以执行未经授权的操作或泄露敏感信息。

示例 1:以下代码演示了向使用 Spring AI 的 AI 聊天客户端注入系统提示:

@GetMapping("/prompt_injection")
String generation(String userInput1, ...) {
return this.clientBuilder.build().prompt()
.system(userInput1)
.user(...)
.call()
.content();
}


在此示例中,攻击者操纵未经验证的可能导致安全漏洞的系统提示输入。

Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM users WHERE ...");
String userName = "";

if (rs != null) {
rs.next();

Abstract
应用程序允许用户污染原型。
Explanation
原型污染是一种攻击手段,它允许恶意用户覆盖对象的原型。
要了解原型污染,首先必须了解原型继承。原型和原型链用于查找 JavaScript 中的属性和函数,从而提供继承。当尝试访问给定对象的属性时,将检查当前对象定义。如果当前对象没有定义属性,则检查原型类。将以递归方式检查原型,直到找到属性,或者不再设置任何原型。

因为 JavaScript 中的大多数对象默认情况下都有一个指向 Object.prototype 的原型,所以如果攻击者可以覆盖对象的原型,他们通常可以覆盖 Object.prototype 的定义,从而影响应用程序内的所有对象。

如果应用程序(或其任何依赖项)依据的是属性可以 undefined 而不是始终显式设置的事实,那么如果原型已被污染,应用程序可能会无意中从原型而不是预期的对象中进行读取。

在以下情况下可能发生原型污染:

1.数据从一个不可信数据源进入程序。



2.将数据传递到允许覆盖原型的 API。

示例 1:以下代码使用了一个易受攻击的 lodash 版本污染对象的原型:


import * as lodash from 'lodash'
...
let clonedObject = lodash.merge({}, JSON.parse(untrustedInput));
...


此时,如果不受信任的输入为 {"__proto__": { "isAdmin": true}},则 Object.prototype 将定义 isAdmin = true

考虑应用程序中稍后存在以下代码。


...
let config = {}
if (isAuthorizedAsAdmin()){
config.isAdmin = true;
}
...
if (config.isAdmin) {
// do something as the admin
}
...


即使 isAdmin 仅在 isAuthorizedAdmin() 返回 true 时才应设置为 true,但由于应用程序无法在 else 条件下设置 config.isAdmin = false,因此它依据的是 config.isAdmin === undefined === false 这一事实。
不幸的是,由于原型已被污染,因此 config 的原型现已设置 isAdmin === true,因此允许绕过管理员授权。
