弱點
Abstract
使用非特定版本擷取組建相依項,會使組建系統易受惡意二進位程式的侵害或造成系統產生意外的運作方式。
Explanation
Dockerfile 可以為相依項和基本映像指定一個沒有界線的版本範圍。如果攻擊者能將惡意版本的相依項新增至儲存庫,或欺騙組建系統從攻擊者控制的儲存庫下載相依項,那麼如果 docker 設定為沒有特定版本的相依項時,則 docker 將以無訊息方式下載並執行遭入侵的相依項。

這種類型的弱點可能因為供應鏈攻擊而被利用,在供應鏈攻擊中,攻擊者可運用開發人員的錯誤組態,接著誤植域名,然後可將惡意套件新增至開放原始碼儲存庫。這種類型的攻擊利用對已發佈套件的信任來獲取存取權限並竊取資料。

在 docker 中,latest 標籤會自動指示未使用摘要或唯一標籤為其提供版本的映像的版本層級。Docker 會自動指派 latest 標籤做為指向最新映像資訊清單檔案的機制。由於標籤是可變的,所以攻擊者可使用 latest (或弱標籤,如imagename-lst, imagename-last, myimage) 取代映像或階層。

範例 1:以下組態指示 Docker 挑選使用最新 ubuntu 版本的基本映像。

FROM ubuntu:Latest
...


Docker 不會驗證設定為支援套件管理器的儲存庫是否值得信賴。

範例 2:以下組態指示套件管理器 zypper 擷取指定套件的最新版本。

...
zypper install package
...

Example 2 中,如果儲存庫遭到入侵,攻擊者可能很容易便上傳符合動態標準的版本,使 zypper 下載相依項的惡意版本。

Abstract
Dockerfile 設定了以 root 使用者身分執行的容器
Explanation
Dockerfile 中包含的 USER 指令設為 root 時,會擁有能在容器內進行變更的過高特權。這違反了以最低特權執行映像的原則。通常,安裝套件和建立資料夾可能需要 root 權限。安裝完成後,最好的做法是新增具有限制特權的使用者。

Abstract
Dockerfile 會開啟 1024 以下的容器連接埠。
Explanation
依據預設,Docker 會允許將具有特權的連接埠繫結至容器,並且如果使用者未宣告連接埠,則 Docker 會將容器連接埠對應至 49153-65535 範圍內的可用連接埠。在許多情況下,需要開啟某些連接埠才能執行服務,並且隨著時間的流逝,開啟的連接埠數量可能會越來越多。開啟的連接埠會增加攻擊面,對於以更高特權執行的服務更是如此。請確保僅開啟該特定服務所需的連接埠。當服務不需要更高的特權時,請在具有特權的連接埠範圍之外的連接埠上執行服務。

Abstract
顯示敏感的主機目錄可能會使攻擊者能存取重要的系統資訊
Explanation
您可以使用 docker inspect 和 history 指令從公開的 Docker 映像檔重建構 Dockerfile,或者透過第三方工具自動執行此程序。如果使用 ADD/COPY 指令新增了敏感資訊,則攻擊者可以重新建立每個 docker 層以取得該資訊。

使用 Volumes 也可能公開敏感目錄。如果需要使用 Volumes 來保存資料,請避免掛接敏感目錄。

Abstract
在同一個記憶體位址呼叫 free() 兩次會導致 Buffer overflow。
Explanation
當不止一次地在同一個記憶體位址將 free() 做為一個引數來呼叫,就會出現 double free (釋放相同的記憶體空間兩次) 錯誤。



以相同值呼叫 free() 兩次,會導致 Buffer overflow。當程式使用相同引數呼叫 free() 兩次,就會毀損程式中的記憶體管理資料結構。這樣的毀損會使程式當機,或者在某些情況下,還會導致之後兩次的 malloc() 呼叫回傳相同的指標。如果 malloc() 兩次回傳值都相同,且程式之後讓攻擊者控制整個已經寫入雙倍分配記憶體的資料,此程式就變得容易受到 Buffer overflow 攻擊。

範例 1:以下程式碼顯示關於 double free (釋放相同的記憶體空間兩次) 弱點的簡單範例。


char* ptr = (char*)malloc (SIZE);
...
if (abrt) {
free(ptr);
}
...
free(ptr);


Double free 弱點的產生有兩個常見的原因 (有時候這兩個原因會同時出現):

- 錯誤條件以及其他異常情況。

- 對於程式中負責釋放記憶體的部分混淆了。

雖然某些 double free (釋放相同的記憶體空間兩次) 弱點的複雜程度不會比之前這個範例高出太多,但是其中大部分弱點分散在好幾百行的程式碼中,甚至是不同的檔案中。程式設計師似乎特別容易受到多次釋放全域變數的影響。

Abstract
在執行期間轉譯使用者所控制的指示,可讓攻擊者執行惡意的程式碼。
Explanation
程式碼插入弱點會在程式設計師錯誤地假設下列情況時發生:直接由使用者所提供的指示僅會執行無害的作業,例如對使用中的使用者物件進行簡單的計算或修改使用者的狀態。但是,若沒有適當的驗證,使用者可能會指定不是程式設計師想要執行的作業。

範例 1:在此典型的程式碼注入範例中,報告會執行基本的計算,讓使用者指定要執行的指令。


...
user_ops = request->get_form_field( 'operation' ).
CONCATENATE: 'PROGRAM zsample.| FORM calculation. |' INTO code_string,
calculator_code_begin user_ops calculator_code_end INTO code_string,
'ENDFORM.|' INTO code_string.
SPLIT code_string AT '|' INTO TABLE code_table.
GENERATE SUBROUTINE POOL code_table NAME calc_prog.
PERFORM calculation IN PROGRAM calc_prog.
...


operation 參數是理想值時,程式會正常運作。不過,如果攻擊者指定同時為有效且惡意的語言作業,則會使用父系程序的完整權限來執行那些作業。此類攻擊在插入的程式碼存取系統資源或執行系統指令時更危險。例如,如果攻擊者指定「MOVE 'shutdown -h now' to cmd.CALL 'SYSTEM' ID 'COMMAND' FIELD cmd ID 'TAB' FIELD TABL[].」做為 operation 的值,則會在主機系統上執行系統關機指令。

Abstract
在執行期間轉譯使用者所控制的指示,可讓攻擊者執行惡意的程式碼。
Explanation
許多現代的程式語言均允許動態轉譯來源指示。此功能可讓程式設計師根據使用者的輸入執行動態指示。程式碼插入弱點會在程式設計師錯誤地假設下列情況時發生:直接由使用者所提供的指示僅會執行無害的作業,例如對使用中的使用者物件進行簡單的計算或修改使用者的狀態。但是,若沒有適當的驗證,使用者可能會指定不是程式設計師想要執行的作業。

範例 1:在此典型的程式碼注入範例中,應用程式會實作基本的計算機,讓使用者指定要執行的指令。


...
var params:Object = LoaderInfo(this.root.loaderInfo).parameters;
var userOps:String = String(params["operation"]);
result = ExternalInterface.call("eval", userOps);
...


operation 參數是良性的值時,例如「8 + 7 * 2」,程式會正常運作。在此案例中,會指定 result 變數的值為 22。不過,如果攻擊者指定同時為有效且惡意的語言作業,則會使用父系程序的完整權限來執行這些作業。當主要語言提供系統資源的存取權限或允許執行系統指令時,這類攻擊會更加危險。在 ActionScript 案例中,攻擊者可能使用此弱點執行 Cross-site scripting 攻擊。

Abstract
在執行期間轉譯使用者所控制的指示,可讓攻擊者執行惡意的程式碼。
Explanation
許多現代的程式語言均允許動態轉譯來源指示。此功能可讓程式設計師根據使用者的輸入執行動態指示。程式碼插入弱點會在程式設計師錯誤地假設下列情況時發生:直接由使用者所提供的指示僅會執行無害的作業,例如對使用中的使用者物件進行簡單的計算或修改使用者的狀態。但是,若沒有適當的驗證,使用者可能會指定不是程式設計師想要執行的作業。

範例 1:在此典型的程式碼注入範例中,應用程式會實作基本的計算機,讓使用者指定要執行的指令。


...
userOp = form.operation.value;
calcResult = eval(userOp);
...


operation 參數是良性的值時,例如「8 + 7 * 2」,程式會正常運作。在此案例中,會指定 calcResult 變數的值為 22。不過,如果攻擊者指定同時為有效且惡意的語言作業,則會使用父系程序的完整權限來執行這些作業。當主要語言提供系統資源的存取權限或允許執行系統指令時,這類攻擊會更加危險。在 JavaScript 案例中,攻擊者可能使用此弱點執行 Cross-site scripting 攻擊。

Explanation
許多現代的程式語言均允許動態轉譯來源指示。此功能可讓程式設計師根據使用者的輸入執行動態指示。程式碼插入弱點會在程式設計師錯誤地假設下列情況時發生:直接由使用者所提供的指示僅會執行無害的作業,例如對使用中的使用者物件進行簡單的計算或修改使用者的狀態。但是,若沒有適當的驗證,使用者可能會指定不是程式設計師想要執行的作業。

範例 1:以下程式碼使用來自 UITextField 的輸入,以便在 WKWebView 中動態變更內容的背景色彩:


...
@property (strong, nonatomic) WKWebView *webView;
@property (strong, nonatomic) UITextField *inputTextField;
...
[_webView evaluateJavaScript:[NSString stringWithFormat:@"document.body.style.backgroundColor="%@";", _inputTextField.text] completionHandler:nil];
...


當 UITextField 輸入是理想值時 (例如「blue」),程式會正常運作,在此情況下,webView 內的 <body> 元素會具有藍色背景樣式。然而,如果攻擊者提供的惡意輸入仍然有效,便可能可以執行任意 JavaScript 程式碼。例如,由於 JavaScript 可以存取某些類型的私密資訊,如 Cookie,因此如果攻擊者指定 "white";document.body.innerHTML=document.cookie;"" 做為 UITextField 的輸入,則 Cookie 資訊會明顯寫入頁面。當基礎語言提供系統資源的存取權或允許執行系統指令時,這類攻擊會更加危險,因為在那些情況下,會使用父系程序的完整權限來執行插入的程式碼。

operation 參數是良性的值時,例如「8 + 7 * 2」,程式會正常運作。在此案例中,會指定 result 變數的值為 22。不過,如果攻擊者指定同時為有效且惡意的作業,則會使用父系程序的完整權限來執行這些作業。當主要語言提供系統資源的存取權限或允許執行系統指令時,這類攻擊會更加危險。例如,如果攻擊者指定「exec('shutdown -h now')」做為 operation 的值,則會在主機系統上執行系統關機指令。

Abstract
在執行期間轉譯使用者所控制的指示,可讓攻擊者執行惡意的程式碼。
Explanation
許多現代的程式語言均允許動態轉譯來源指示。此功能可讓程式設計師根據使用者的輸入執行動態指示。程式碼插入弱點會在程式設計師錯誤地假設下列情況時發生:直接由使用者所提供的指示僅會執行無害的作業,例如對使用中的使用者物件進行簡單的計算或修改使用者的狀態。但是,若沒有適當的驗證,使用者可能會指定不是程式設計師想要執行的作業。

範例 1:在此典型的程式碼注入範例中,應用程式會實作基本的計算機,讓使用者指定要執行的指令。


...
userOps = request.GET['operation']
result = eval(userOps)

operation 參數是良性的值時,例如「8 + 7 * 2」,程式會正常運作。在此案例中,會指定 result 變數的值為 22。不過,如果攻擊者指定同時為有效且惡意的作業,則會使用父系程序的完整權限來執行這些作業。當主要語言提供系統資源的存取權限或允許執行系統指令時,這類攻擊會更加危險。例如,如果攻擊者指定「os.system('shutdown -h now')」做為 operation 的值,則會在主機系統上執行系統關機指令。

如果攻擊者要提交參數 operation "system(\"nc -l 4444 &\");8+7*2",則此作業會開啟連結埠 4444 以偵聽機器上的連線,且仍然會將值 22 回傳到 result

Abstract
在執行期間轉譯使用者所控制的指示,可讓攻擊者執行惡意的程式碼。
Explanation
許多現代的程式語言均允許動態轉譯來源指示。此功能可讓程式設計師根據使用者的輸入執行動態指示。程式碼插入弱點會在程式設計師錯誤地假設下列情況時發生:直接由使用者所提供的指示僅會執行無害的作業,例如對使用中的使用者物件進行簡單的計算或修改使用者的狀態。但是,若沒有適當的驗證,使用者可能會指定不是程式設計師想要執行的作業。

範例 1:以下程式碼使用來自 UITextField 的輸入,以便在 WKWebView 中動態變更內容的背景色彩:


...
var webView : WKWebView
var inputTextField : UITextField
...
webView.evaluateJavaScript("document.body.style.backgroundColor="\(inputTextField.text)";" completionHandler:nil)
...


當 UITextField 輸入是理想值時 (例如「blue」),程式會正常運作,在此情況下,webView 內的 <body> 元素會具有藍色背景樣式。然而,如果攻擊者提供的惡意輸入仍然有效,便可能可以執行任意 JavaScript 程式碼。例如,由於 JavaScript 可以存取某些類型的私密資訊,如 Cookie,因此如果攻擊者指定 "white";document.body.innerHTML=document.cookie;"" 做為 UITextField 的輸入,則 Cookie 資訊會明顯寫入頁面。當基礎語言提供系統資源的存取權或允許執行系統指令時,這類攻擊會更加危險,因為在那些情況下,會使用父系程序的完整權限來執行插入的程式碼。

Abstract
從不可信賴的來源執行任意來源指示會導致執行惡意的程式碼。
Explanation
許多現代的語言均允許動態轉譯來源指示。若程式設計師需要對資料執行由使用者提供的指示,但寧可運用基本的語言建構,也不要執行程式碼來解譯使用者輸入,在這種情況下可使用這個功能。使用者所提供的指示一般來說為無害的作業,例如:在使用中的使用者物件上進行計算、修改使用者物件的狀態等等。不過,如果程式設計師思考不夠周延,使用者可能會執行程式設計師料想之外的作業。

範例 1:可由使用者指定的基本程式建構的常見應用程式範例即為計算機。下列 ASP 程式碼可接受使用者所要計算與回傳的基本數學運算:


...
strUserOp = Request.Form('operation')
strResult = Eval(strUserOp)
...


程式會執行計畫執行的計算,如參數為「8 + 7 * 2」的 operation 的範例。strResult 變數所回傳的值為 22。但是,如果使用者指定其他有效的語言作業,不僅會執行那些作業,還會使用父系程序的完整權限來執行。當基本語言提供系統資源的存取權限或允許執行系統指令時,執行任意的程式碼會變得更加危險。例如:如果攻擊者將 operation 指定為「Shell('C:\WINDOWS\SYSTEM32\TSSHUTDN.EXE 0 /DELAY:0 /POWERDOWN')」,則可能會在主機系統上執行關閉指令。

Abstract
允許未經驗證的使用者輸入去影響動態執行程式碼的執行期間環境,能允許攻擊者執行惡意程式碼。
Explanation
許多現代的程式語言均允許動態轉譯來源指示。此功能可讓程式設計師根據使用者的輸入執行動態作業。當程式設計師允許部分使用者提供資料去修改一部分動態執行程式碼的執行期間環境時,會發生程式碼控制弱點。若沒有適當的驗證,使用者可能會指定不是程式設計師想要執行的作業。

範例 1:在此範例中,應用程式從 Web 應用程式中取得指令碼執行範圍。


...
ScriptEngineManager scriptEngineManager = new ScriptEngineManager();
ScriptEngine scriptEngine = scriptEngineManager.getEngineByExtension("js");
ScriptContext newContext = new SimpleScriptContext();
Bindings engineScope = newContext.getBindings(request.getParameter("userName"));

userOps = request.getParameter("operation");
Object result = scriptEngine.eval(userOps,newContext);
...


page_scope 參數是預期的使用者名稱,程式會正常運作。不過,如果攻擊者指定 GLOBAL_SCOPE 的值,操作將會存取由同一個 ScriptEngine 建立的所有引擎中的所有屬性。

Abstract
檔案透過未加密的通道載入 script。
Explanation
透過未加密的通道包含來自網站的可執行內容,會使攻擊者能夠執行 Man-in-the-Middle (MiTM) 攻擊。這會使攻擊者能夠載入自己的內容,執行這些內容就如同屬於原始網站一樣。

範例 1:請考慮以下 script 標籤:

<script src="http://www.example.com/js/fancyWidget.js"></script>


如果攻擊者正在監聽使用者與伺服器之間的網路流量,就可以模擬或操縱來自 www.example.com 的內容以載入自己的 JavaScript。

Abstract
程式會使用不受信任的位址來執行 JNDI 查閱,這可能會讓攻擊者遠端執行任意 Java 程式碼。
Explanation
如果攻擊者能夠控制 JNDI 查找作業的位址,就能夠遠端執行任意程式碼,方法是將位址指向其所控制的伺服器,並透過自訂 Object Factory 將 JNDI 具名參考傳回 RMI 儲存的物件。

範例 1:以下程式碼會使用不可信賴的資料執行 JNDI 查詢。


...
String address = request.getParameter("address");

Properties props = new Properties();
props.put(Provider_URL, "rmi://secure-server:1099/");
InitialContext ctx = new InitialContext(props);
ctx.lookup(address);

Abstract
在執行期間轉譯使用者所控制的指示,可讓攻擊者執行惡意程式碼。
Explanation
許多現代的程式語言均允許動態轉譯來源指示。此功能可讓程式設計師根據使用者的輸入執行動態指示。程式碼插入弱點會在程式設計師錯誤地假設下列情況時發生:直接由使用者所提供的指示僅會執行無害的作業,例如對使用中的使用者物件進行簡單的計算或修改使用者的狀態。但是,若沒有適當的驗證,使用者可能會指定不是程式設計師想要執行的作業。

範例 1:在這個程式碼的插入範例中,要求參數會繫結到受評估的 razor 範本中。


...
string name = Request["username"];
string template = "Hello @Model.Name! Welcome " + name + "!";
string result = Razor.Parse(template, new { Name = "World" });
...
operation 是良性的值時 (例如「John」),程式會正常運作;在此案例中,result 變數指定的值是「Hello World!Welcome John!」。不過,如果攻擊者指定同時為有效且惡意的語言作業,則會使用父系程序的完整權限來執行那些作業。當主要語言提供系統資源的存取權限或允許執行系統指令時,這類攻擊會更加危險。舉例來說,Razor 允許呼叫 C# 物件,如果攻擊者指定「@{ System.Diagnostics.Process proc = new System.Diagnostics.Process(); proc.EnableRaisingEvents=false; proc.StartInfo.FileName=\"calc\"; proc.Start(); }」 做為 name 的值,則會在主機系統上執行系統指令。

Abstract
在執行期間轉譯使用者所控制的指示,可讓攻擊者執行惡意程式碼。
Explanation
許多現代的程式語言均允許動態轉譯來源指示。此功能可讓程式設計師根據使用者的輸入執行動態指示。程式碼插入弱點會在程式設計師錯誤地假設下列情況時發生:直接由使用者所提供的指示僅會執行無害的作業,例如對使用中的使用者物件進行簡單的計算或修改使用者的狀態。但是,若沒有適當的驗證,使用者可能會指定不是程式設計師想要執行的作業。

範例 1:在此典型的程式碼注入範例中,應用程式會實作基本的計算機,讓使用者指定要執行的指令。


...
ScriptEngineManager scriptEngineManager = new ScriptEngineManager();
ScriptEngine scriptEngine = scriptEngineManager.getEngineByExtension("js");
userOps = request.getParameter("operation");
Object result = scriptEngine.eval(userOps);
...


operation 參數是良性值時,例如「8 + 7 * 2」,程式會正常運作。在此情況下,會指定 result 變數的值為 22。不過,如果攻擊者指定有效且惡意的語言作業,則會使用父系程序的完整權限來執行這些作業。當主要語言提供系統資源的存取權限或允許執行系統指令時,這類攻擊會更加危險。例如,JavaScript 允許叫用 Java 物件,如果攻擊者指定「java.lang.Runtime.getRuntime().exec("shutdown -h now")」作為 operation 的值,則會在主機系統上執行關機指令。

Abstract
從不可信賴的來源執行任意來源指示會導致執行惡意程式碼。
Explanation
許多現代的語言均允許動態轉譯來源指示。若程式設計師需要對資料執行由使用者提供的指示,但寧可運用基本的語言建構,也不要執行程式碼來解譯使用者輸入,在這種情況下可使用這個功能。使用者所提供的指示一般來說為無害的作業,例如:在使用中的使用者物件上進行計算、修改使用者物件的狀態等等。不過,如果程式設計師思考不夠周延,使用者可能會執行程式設計師料想之外的作業。

範例 1:可由使用者指定的基本程式建構的常見應用程式範例即為計算機。下列 ASP 程式碼可接受使用者所要計算與回傳的基本數學運算:


...
strUserOp = Request.Form('operation')
strResult = Eval(strUserOp)
...


程式會執行計畫執行的計算,如參數為「8 + 7 * 2」的 operation 的範例。strResult 變數所回傳的值為 22。但是,如果使用者指定其他有效的語言作業,不僅會執行那些作業,還會使用父系程序的完整權限來執行。當基本語言提供系統資源的存取權限或允許執行系統指令時,執行任意的程式碼會變得更加危險。例如:如果攻擊者將 operation 指定為「Shell('C:\WINDOWS\SYSTEM32\TSSHUTDN.EXE 0 /DELAY:0 /POWERDOWN')」,則可能會在主機系統上執行關閉指令。

Abstract
指定類別中可序列化的 Delegate 欄位會在還原序列化類別時,引入任意程式碼執行漏洞。
Explanation
Delegate 類型用於保留方法呼叫的參考,該方法呼叫可於稍後在使用者程式碼中叫用。.NET 會使用自訂的序列化方法來序列化 Delegate 類型,並利用 System.DelegateSerializationHolder 類別來儲存附加至或歸屬於 Delegate 的方法資訊。Delegate 物件的已序列化串流不適合持續性儲存或傳遞至遠端應用程式,因為攻擊者可以將方法資訊取代為指向惡意物件圖形的方法資訊,所以攻擊者將可以執行任意程式碼。

範例 1:以下類別包含可序列化的 Delegate 欄位,並且會在 Executor 方法中叫用:


...
[Serializable]
class DynamicRunnner
{
Delegate _del;
string[] _arg;
public DynamicRunnner(Delegate dval, params string[] arg)
{
_del = dval;
_arg = arg;
}
public bool Executor()
{
return (bool)_del.DynamicInvoke(_arg);
}
}
...


如果開發人員還原序列化 Example 1 中提及之類別的不受信任的串流,攻擊者將方法資訊取代為指向 Process.Start 的方法資訊,將會導致在呼叫 Executor 方法時建立任意程序。

Abstract
使用 BeanUtils 還原序列化使用者控制的物件可能會讓攻擊者在伺服器上執行任意程式碼、濫用應用程式邏輯和/或造成阻斷服務。
Explanation
BeanUtils 用於還原序列化使用者控制的資料 (在此案例中為 Redis 雜湊),此資料包含指派給物件欄位的類型鑑別子與值。 BeanUtils 透過叫用這些欄位的 setter 來重建物件,會讓攻擊者將任意資料傳遞給任意類別 setter。 如果攻擊者可以指定要重建之物件的類別,並能夠強制應用程式利用使用者控制的資料執行任意 setter,他們可能會在 Redis 雜湊的還原序列化期間執行任意程式碼。

範例 1:下列程式碼會使用 BeanUtilsHashMapper 來還原序列化 Redis 雜湊,這樣做可能會讓攻擊者控制此類雜湊來執行任意程式碼。


HashMapper<Person, String, String> hashMapper = new BeanUtilsHashMapper<Person>(Person.class);
Person p = hashMapper.fromHash(untrusted_map);

Abstract
在執行階段,還原序列化使用者控制的物件串流可能會讓攻擊者在伺服器上執行任意程式碼、濫用應用程式邏輯和/或造成阻斷服務。
Explanation
.NET 序列化會將物件圖形變成包含物件本身及必要中繼資料的位元組或 XML 串流,以便從串流重建這些物件圖形。開發人員可以建立自訂程式碼來協助處理 .NET 物件的還原序列化,在此過程中,他們可以將已還原序列化的物件取代為不同的物件或代理伺服器。在物件重建的過程中,並在物件傳回至應用程式並轉換為預期的類型之前,會進行自訂的還原序列化程序。當開發人員嘗試強制執行某個預期的類型時,程式碼可能已經執行。

範例 1:以下函數採用來自連線的 Stream 物件做為輸入,並將其還原序列化回 .NET 物件。然後在將其轉換為字串物件清單後傳回結果:


...
List <string> Deserialize(Stream input)
{
var bf = new BinaryFormatter();
var result = (List <string>)bf.Deserialize(input);
return result;
}
...


為了更好地瞭解,Example 1 可以按如下方式進行重寫:

範例 2:

...
List <string> Deserialize(Stream input)
{
var bf = new BinaryFormatter();
object tmp = bf.Deserialize(input);
List <string> result = (List <string>)tmp;
return result;
}
...


Example 2 中,只要輸入串流有效,無論類型是否為 List <string>,還原序列化作業都會成功。

在必須存在於 bin 資料夾或位於 GAC 中且攻擊者不能插入的可序列化類別中,會定義自訂還原序列化常式,所以這些攻擊的可利用性取決於應用程式環境中的可用類別。遺憾的是,常見的第三方類別、甚至是 .NET 類別可能會被濫用於耗盡系統資源、刪除檔案、部署惡意檔案或執行任意程式碼。

Abstract
在執行階段,還原序列化使用者控制的物件串流可能會讓攻擊者在伺服器上執行任意程式碼、濫用應用程式邏輯和/或造成阻斷服務。
Explanation
Java 序列化會將物件圖形變成包含物件本身及必要中繼資料的位元組串流,以便從位元組串流重建這些物件圖形。開發人員可以建立自訂程式碼來協助處理 Java 物件的還原序列化,在此過程中,他們可以將已還原序列化的物件取代為不同的物件或代理伺服器。在物件重建的過程中,並在物件傳回至應用程式並轉換為預期的類型之前,會進行自訂的還原序列化程序。當開發人員嘗試強制執行某個預期的類型時,程式碼可能已經執行。

在必須存在於執行階段類別路徑中且攻擊者不能插入的可序列化類別中,會定義自訂還原序列化常式,所以這些攻擊的可利用性取決於應用程式環境中的可用類別。遺憾的是,常見的第三方類別、甚至是 JDK 類別可能會被濫用於耗盡 JVM 資源、部署惡意檔案或執行任意程式碼。

Abstract
在執行期間還原序列化使用者所控制的資料,可讓攻擊者執行任意程式碼。
Explanation
Python 官方說明文件表示:


The pickle module is not intended to be secure against erroneous or maliciously constructed data. Never unpickle data received from an untrusted or unauthenticated source.


Pickle 是一個強大的序列化程式庫,為開發者提供簡便的方式傳輸物件並將其序列化為自訂 Pickle 表示。Pickle 允許任意物件透過定義 __reduce__ 方法聲明其應如何還原序列化。此方法應傳回 callable 及其引數。Pickle 將使用提供的引數呼叫 callable 來建構新物件,允許攻擊者執行任意指令。

desc.dataflow.python.dynamic_code_evaluation_unsafe_pickle_deserialization
Abstract
允許在 TensorFlow 中進行不安全的還原序列化,可能允許透過 lambda 執行任意程式碼,從而對應用程式帶來重大安全風險。
Explanation
使用 TensorFlow 時,enable_unsafe_deserialization() 會允許攻擊者將 lambda 或其他 Python 可呼叫物件還原序列化。雖然此功能對於彈性和還原複雜模型非常有用,但如果序列化資料可被利用,則會帶來弱點。

範例 1:以下 Python 程式碼說明了如果序列化資料不安全,啟用不安全的還原序列化可能會如何被利用:

import tensorflow as tf

tf.keras.config.enable_unsafe_deserialization()

model = tf.keras.models.load_model('evilmodel_tf.keras')
model([])



此範例示範了在未確保資料來源完全安全的情況下使用 enable_unsafe_deserialization() 時的潛在危險。
desc.structural.python.dynamic_code_evaluation_unsafe_tensorflow_deserialization
Abstract
在執行期間還原序列化使用者所控制的 XML 文件,可讓攻擊者在伺服器上執行惡意的任意程式碼。
Explanation
XStream 程式庫為開發人員提供輕鬆的物件傳送方式,同時將其序列化為 XML 文件。但是,XStream 還原序列化可能會讓攻擊者在伺服器上執行任意 Java 程式碼。

範例 1:以下 Java 程式碼顯示了 XStream 處理不可信賴輸入的範例。


XStream xstream = new XStream();
String body = IOUtils.toString(request.getInputStream(), "UTF-8");
Contact expl = (Contact) xstream.fromXML(body);

desc.dataflow.java.dynamic_code_evaluation_unsafe_xstream_deserialization
Abstract
還原序列化使用者控制的 YAML 串流可能會讓攻擊者在伺服器上執行任意程式碼、濫用應用程式邏輯和/或造成阻斷服務。
Explanation
YAML 序列化程式庫 (可將物件圖形轉換成 YAML 格式的資料) 可能包含必要的中繼資料,進而能夠從 YAML 串流重建物件。 如果攻擊者可以指定要重建之物件的類別,並能夠強制應用程式利用使用者控制的資料執行任意 Setter,他們可能會在 YAML 串流的還原序列化期間執行任意程式碼。

範例: 下列範例使用 YamlDotNet 解析器,將不可信賴的 YAML 字串還原序列化。


var yamlString = getYAMLFromUser();

// Setup the input
var input = new StringReader(yamlString);

// Load the stream
var yaml = new YamlStream();
yaml.Load(input);

Abstract
還原序列化使用者控制的 YAML 串流可能會讓攻擊者在伺服器上執行任意程式碼、濫用應用程式邏輯和/或造成阻斷服務。
Explanation
YAML 序列化程式庫 (可將物件圖形轉換成 YAML 格式的資料) 可能包含必要的中繼資料,進而能夠從 YAML 串流重建物件。 如果攻擊者可以指定要重建之物件的類別,並能夠強制應用程式利用使用者控制的資料執行任意 Setter,他們可能會在 YAML 串流的還原序列化期間執行任意程式碼。

JDK XMLEncoder 與 XMLDecoder 類別能為開發人員提供輕鬆方式以保留物件,同時將其序列化為 XML 文件。但是,XMLEncoder 也允許開發人員序列化方法呼叫,若攻擊者能提供將要由 XMLDecoder 還原序列化的 XML 文件,則能夠在伺服器上執行任意程式碼。

範例 1:以下 Java 程式碼顯示了處理不可信賴輸入的 XMLDecoder 執行個體。


XMLDecoder decoder = new XMLDecoder(new InputSource(new InputStreamReader(request.getInputStream(), "UTF-8")));

Object object = decoder.readObject();
decoder.close();
範例 1:以下 XML 文件將個體化 ProcessBuilder 物件,並叫用其靜態 start() 方法以執行 Windows 小算盤。


<java>
<object class="java.lang.ProcessBuilder">
<array class="java.lang.String" length="1" >
<void index="0">
<string>c:\\windows\\system32\\calc.exe</string>
</void>
</array>
<void method="start"/>
</object>
</java>
