界: Errors

错误和错误处理代表一类 API。与错误处理相关的错误非常普遍,因此它们应该拥有自己的专属章节。与“API 滥用”一样,有两种情况可以引入与错误相关的安全漏洞:最常见的一种是错误处理不当(或者根本不处理)。第二种是产生错误,这些错误要么(向潜在的攻击者)泄露过多信息,要么难以处理。

Abstract
忽略条件会导致程序无法发现意外状况和错误。
Explanation
几乎每一个对软件系统的严重攻击都是从违反程序员的假设开始的。攻击后,程序员的假设看起来既脆弱又拙劣,但攻击前,许多程序员会在午休时间为自己的种种假设做很好的辩护。

在代码中,很容易发现两个令人怀疑的假设:“一是这个函数调用不可能出错;二是即使出错了,也不会对系统造成什么重要影响。”因此当程序员忽略条件时,这其实就表明了他们是基于上述假设进行的操作。

例 1:下列摘录的代码会忽略 CICS 事务期间可能发生的错误情况。


...
EXEC CICS
INGNORE CONDITION ERROR
END-EXEC.
...


如果事务因为此错误情况而失败,程序会继续执行,就像什么都没有发生一样。程序不会记录任何有关这一特殊情况的依据,因而事后再查找这一异常就可能很困难。

Abstract
忽略异常会导致程序无法发现意外状况和情况。
Explanation
几乎每一次对软件系统的严重攻击都是从违反程序员的假设开始的。攻击发生后,程序员的假设似乎站不住脚,缺乏依据。但在攻击发生之前,许多程序员会在午休时间过后为他们的种种假设做很好的辩护。

在代码中,很容易发现两个令人怀疑的假设:“此方法调用绝不可能出错”和“此调用即使出错也不要紧”。当程序员忽略异常时,这也就隐式地表明他们是基于上述这些假设之一进行的操作。

示例 1:以下代码摘录将忽略 doExchange() 中很少抛出的异常。


try {
doExchange();
}
catch (RareException e) {
// this can never happen
}


如果抛出 RareException,程序将继续执行,就像未发生任何异常情况。该程序未记录表明特殊情况的任何证据,这可能会导致以后无法解释该程序的行为。

Abstract
忽略异常会导致程序无法发现意外状况和情况。
Explanation
几乎每一个对软件系统的严重攻击都是从违反程序员的假设开始的。攻击后,程序员的假设看起来既脆弱又拙劣,但攻击前,许多程序员会在午休时间为自己的种种假设做很好的辩护。

在代码中,很容易发现两个令人怀疑的假设:“一是这个方法调用不可能出错;二是即使出错了,也不会对系统造成什么重要影响。”因此当程序员忽略异常时,这其实就表明了他们是基于上述假设进行的操作。

例 1:下面摘录的代码会忽略一个由 open() 抛出的罕见异常。


try:
f = open('myfile.txt')
s = f.readline()
i = int(s.strip())
except:
# This will never happen
pass


如果抛出 RareException 异常,程序会继续执行,就像什么都没有发生一样。程序不会记录任何有关这一特殊情况的依据,因而事后再查找这一异常就可能很困难。

在代码中,很容易发现两个令人怀疑的假设:“一是这个函数调用不可能出错;二是即使出错了,也不会对系统造成什么重要影响。”因此当程序员忽略异常时,这其实就表明了他们是基于上述假设进行的操作。

例 1:下列代码忽略了在执行插入指令时可能抛出的一些异常。


PROCEDURE do_it_all
IS
BEGIN
BEGIN
INSERT INTO table1 VALUES(...);
COMMIT;
EXCEPTION
WHEN OTHERS THEN NULL;
END;
END do_it_all;


由于该表不存在、未提供所需值或一些其他的原因,运行程序时可能会抛出异常。如果运行失败,我们就无法知道原因,因为该程序不会报告该失败或记录发生了哪种类型的失败。

Abstract
catch 块可以处理的异常种类很多,但往往会由于过多的考虑不应该在此位置处理的各种问题或故障而困扰不已。
Explanation
多个 catch 块看上去繁琐,但使用一个“简约”的 catch 块捕获高级别的异常类(如 Exception),可能会混淆那些需要特殊处理的异常,或是捕获了不应在程序中这一点捕获的异常。本质上,捕获范围过大的异常与“.NET 分类定义异常”这一目的是相违背的,随着程序的增加而抛出新异常时,这种做法会十分危险。而新发生的异常类型也不会被注意到。

示例:以下代码使用了同一方式来处理三种不同的异常类型。


try {
DoExchange();
}
catch (IOException e) {
logger.Error("DoExchange failed", e);
}
catch (FormatException e) {
logger.Error("DoExchange failed", e);
}
catch (TimeoutException e) {
logger.Error("DoExchange failed", e);
}


其实,与其这样,还不如使用一个单独的 catch 块来处理这三种异常,如下所示:


try {
DoExchange();
}
catch (Exception e) {
logger.Error("DoExchange failed", e);
}


但是如果修改 DoExchange(),以抛出需要以某种不同的方式处理的新异常类型,则范围过大的 catch 块会阻止编译器指出这一情况(有新的异常抛出)。除此以外,这个新的捕获块还可处理 ApplicationExceptionNullReferenceException 类型的异常,这些异常的发生并不在程序员的意料之内。

Abstract
该方法抛出了一个过于笼统异常,从而使调用者很难处理和修复发生的错误。
Explanation
声明一种可以抛出 ExceptionThrowable 异常的方法,从而使调用者很难处理和修复发生的错误。Java 异常机制的设置是:调用者可以方便地预计有可能发生的各种错误,并为每种异常情况编写处理代码。同时声明:一个方法抛出一个过于笼统的异常违反该系统。

示例:以下方法抛出了三种类型的异常。


public void doExchange()
throws IOException, InvocationTargetException,
SQLException {
...
}



这样写看上去会显得更加紧凑


public void doExchange()
throws Exception {
...
}


这样做会防碍调用者理解和处理所发生的异常。此外,如果 doExchange() 因为变更了代码,而引入了一个需要不同于之前异常处理方式的新型异常,则不能使用简单的方式来处理该要求。

Abstract
通常来说,捕获 NullPointerException 并不是一个好方法。
Explanation
程序员通常会在以下三种情况中捕获 NullPointerException

1.程序包含一个 null 指针间接引用。捕获生成的异常比修复底层问题更容易。

2. 程序显式地抛出了一个 NullPointerException 异常来标记错误状况。

3. 该代码是测试代码的一部分,为正在测试的类提供了一个异常输入。

在上述三种情况中,只有最后一种是可以接受的。

示例:下列代码错误地捕获了一个 NullPointerException 异常。


try {
mysteryMethod();
}
catch (NullPointerException npe) {
}

Abstract
finally 块中返回会导致异常的丢失。
Explanation
finally 块中的返回指令会导致从 try 块中抛出的异常丢失。

例 1:在下列代码中,第二次调用 doMagic 方法,同时将参数 true 传递给该方法会导致抛出 MagicException 异常,该异常将不会传递给调用者。finally 块中的返回指令会导致异常的丢弃。


public class MagicTrick {

public static class MagicException extends Exception { }

public static void main(String[] args) {

System.out.println("Watch as this magical code makes an " +
"exception disappear before your very eyes!");

System.out.println("First, the kind of exception handling " +
"you're used to:");
try {
doMagic(false);
} catch (MagicException e) {
// An exception will be caught here
e.printStackTrace();
}

System.out.println("Now, the magic:");
try {
doMagic(true);
} catch (MagicException e) {
// No exception caught here, the finally block ate it
e.printStackTrace();
}
System.out.println("tada!");
}

public static void doMagic(boolean returnFromFinally)
throws MagicException {

try {
throw new MagicException();
}
finally {

return;
}
}
}

desc.structural.java.poor_error_handling_return_inside_finally
Abstract
finally 块中返回会导致异常的丢失。
Explanation
finally 块中的返回指令会导致从 try 块中抛出的异常丢失。

示例 1:在下列代码中,第二次调用 doMagic 方法,同时将参数 True 传递给该方法会导致抛出 exception 异常,该异常将不会传递给调用者。finally 块中的返回指令会导致异常的丢弃。

        "disappear before your very eyes!" . PHP_EOL;

echo "First, the kind of exception handling " .
"you're used to:" . PHP_EOL;

try {
doMagic(False);
} catch (exception $e) {
// An exception will be caught here
echo $e->getMessage();
}

echo "Now, the magic:" . PHP_EOL;

try {
doMagic(True);
} catch (exception $e) {
// No exception caught here, the finally block ate it
echo $e->getMessage();
}

echo "Tada!" . PHP_EOL;

function doMagic($returnFromFinally) {
try {
throw new Exception("Magic Exception" . PHP_EOL);
}
finally {
if ($returnFromFinally) {
return;
}
}
}
?>

desc.structural.php.poor_error_handling_return_inside_finally
Abstract
如果重新抛出了 ThreadDeath 错误,则出现问题的线程可能实际上并未终止。
Explanation
如果异步终止了应用程序后需要将其清除,则应仅捕获 ThreadDeath 错误。如果捕获了 ThreadDeath 错误,则将其重新抛出非常重要,因为这样该线程才真正地终止。抛出 ThreadDeath 的目的是终止线程。如果 ThreadDeath 被抑制,则它可以阻止线程停止并导致意外行为,因为代码最初抛出 ThreadDeath 的目的是希望停止该线程。

例 1:下列代码捕获了 ThreadDeath 但未将其重新抛出。

try
{
//some code
}
catch(ThreadDeath td)
{
//clean up code
}

desc.structural.java.poor_error_handling_swallowed_threaddeath
Abstract
使用 finally 块中的 throw 语句会通过 try-catch-finally 破坏逻辑进度。
Explanation
在 Java 中,finally 块通常在其相应的 try-catch 块之后执行,该块通常用于自由分配的资源,例如文件句柄或数据库指针。由于破坏了正常的程序执行,在 finally 块中抛出异常会绕过关键的清除代码。

例 1:在下列代码中,抛出 FileNotFoundException 时,将绕过对 stmt.close() 的调用。

public void processTransaction(Connection conn) throws FileNotFoundException
{
FileInputStream fis = null;
Statement stmt = null;
try
{
stmt = conn.createStatement();
fis = new FileInputStream("badFile.txt");
...
}
catch (FileNotFoundException fe)
{
log("File not found.");
}
catch (SQLException se)
{
//handle error
}
finally
{
if (fis == null)
{
throw new FileNotFoundException();
}

if (stmt != null)
{
try
{
stmt.close();
}
catch (SQLException e)
{
log(e);
}
}
}
}

desc.structural.java.poor_error_handling_throw_inside_finally
Abstract
未能适当处理的异常可能导致应用程序产生意想不到的状态和状况。
Explanation
以下情况中会出现 Unhandled Exception 漏洞:

1. 一个异常被抛出

2. 在异常离开当前页之前,未能对其进行适当地处理。

几乎每一个对软件系统的严重攻击都是从违反程序员的假设开始的。攻击后,程序员的假设看起来既脆弱又拙劣,但攻击前,许多程序员会在午休时间为自己的种种假设做很好的辩护。

代码中两个容易识破的可疑假设是:“该操作从不会失败”和“如果该操作失败了也没关系”。如果程序员没有抓住某个操作抛出的异常,则间接地表明了他们是基于这些假设进行的操作。

Abstract
没有显式地处理 SSL 异常可能会导致应用程序无法发现意外状况和情况。
Explanation
未处理的 SSL 异常会在以下情况中发生:

1. 抛出特定的 SSL 异常。

2. 未显式地处理异常。

特定 SSL 异常 javax.net.ssl.SSLHandshakeExceptionjavax.net.ssl.SSLKeyExceptionjavax.net.ssl.SSLPeerUnverifiedException 都可以传达与 SSL 连接相关的重要错误。如果没有显式地处理这些错误,连接会被处于一种意想不到的、潜在不安全的状态。

几乎每一个对软件系统的严重攻击都是从违反程序员的假设开始的。攻击后,程序员的假设看起来既脆弱又拙劣,但攻击前,许多程序员会在午休时间为自己的种种假设做很好的辩护。

代码中两个容易识破的可疑假设是:“该操作从不会失败”和“如果该操作失败了也没关系”。如果程序员没有抓住某个操作抛出的异常,则间接地表明了他们是基于这些假设进行的操作。
