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。

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: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 參數是良性值時,例如「8 + 7 * 2」,程式會正常運作。在此情況下,會指定 calcResult 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。在 JavaScript 案例中,攻擊者可能使用此弱點執行 Cross-site scripting 攻擊。

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: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 欄位可能會在還原序列化該類別之時或之後引發任意程式碼執行弱點。
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。因此,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,這會在還原序列化之時或之後叫用時導致任意程式碼執行弱點。

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。

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。

.NET 序列化用於不同的架構。例如:

1.所有版本的 ASP.NET 都會忽略 EnableViewStateMac 屬性的設定,因為它會在應用程式中引入遠端程式碼執行弱點。但是,開發人員可以使用 aspnet:AllowInsecureDeserialization 設定覆寫此功能,並因此使應用程式易受遠端程式碼執行的攻擊。

範例 1:在以下範例中,aspnet:AllowInsecureDeserialization 設定為 true

<appSettings>
<add key="aspnet:AllowInsecureDeserialization" value="true" />
</appSettings>


2.依賴執行階段類型驗證的 .NET Remoting 系統必須還原序列化遠端串流才能開始使用它,並且未經授權的用戶端可能會嘗試利用還原序列化的時刻。.NET Framework 遠端處理提供了兩種層級的自動還原序列化,即 LowFullLow (預設值) 透過僅還原序列化與最基本的遠端處理功能關聯的類型 (例如,自動還原序列化遠端基礎架構類型、一組有限的系統實作的類型和一組基本的自訂類型) 來防止還原序列化攻擊。Full 還原序列化層級支援在所有情況下遠端處理支援的所有類型的自動還原序列化。

範例 2:在以下範例中,typeFilterLevel 設定為 Full

<system.runtime.remoting>
<application>
<channels>
<channel ref="tcp" port="2000">
<serverProviders>
<formatter ref="soap" typeFilterLevel="Full" />
<formatter ref="binary" typeFilterLevel="Full" />
</serverProviders>
<clientProviders>
<formatter ref="binary"/>
</clientProviders>
</channel>
</channels>
</application>
...
</system.runtime.remoting>

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,他們甚至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。

有些 Spring 服務匯出工具會在傳輸層於幕後使用 Java 序列化 (包括 RMI、JMSInvoker 和 HTTPInvoker)。

範例 1:RMIServiceExporter 暴露 TestService 方法。

Abstract
還原序列化使用者控制的 Json 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
Json 序列化程式庫 (可將物件圖形轉換成 Json 格式的資料) 可能包含必要的中繼資料,進而能夠從 Json 串流重建物件。如果攻擊者可以指定要重建之物件的類型,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 Json 串流的還原序列化期間執行任意程式碼。

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。
