groovy: remote execution of untrusted code in class MethodClosure

A flaw was discovered in the way applications using Groovy used the standard Java serialization mechanism. A remote attacker could use a specially crafted serialized object that would execute code directly when deserialized. All applications which rely on serialization and do not isolate the code...

Jenkins CI Server XStream Insecure Deserialization (CVE-2016-0792)

An insecure deserialization vulnerability has been reported in Jenkins CI Server. This vulnerability is due to the inclusion of the Groovy library in the classpath combined with the insecure deserialization employing the XStream library. A remote, unauthenticated attacker can exploit this...

Jenkins < 1.642.2 / 1.650 Java Object Deserialization RCE

The remote web server hosts a version of Jenkins or Jenkins Enterprise that is prior to 1.642.2 or 1.650. It is, therefore, affected by a Java deserialization vulnerability. An unauthenticated, remote attacker can exploit this, by deserializing specific java.rmi and sun.rmi objects, to start a JR...

Apache Groovy MethodClosure 远程代码执行漏洞（CVE-2015-3253）

问题大概出现在了 MethodClosure 类上, 该类定义以及方法如下图: 该类的描述为 Represents a method on an object using a closure which can be invoked at any time, 大概意思就是通过构建一个指定对象以及调用方法的Closure 的实例并且可以在任何时候进行调用。上图红色线标记的方法即为触发构建好的对象以及指定方法的函数，我们跟进看看该方法最终是怎么样执行的。 通过该方法的注释可以知道该方法的作用为调用指定对象的指定方法，所以 MethodClosure 类中构造方法中的两个参数的意思为 owne...

XStream 反序列化漏洞

Xstream 的反序列化漏洞的根源就是 Groovy 组件的问题参考 Apache Groovy MethodClosure 远程代码执行漏洞（CVE-2015-3253），只不过在 Xstream 中进行反序列化时恰好有触发存在缺陷函数的点，也就是 Xstream 在反序列化时调用了 Mapput 函数将构造好的 Expando 实例作为 key 添加到集合中时触发了代码执行，如下图: 这里的 key 就是我们构造的 Expando 的实例对象。 在构造 EXP 时，首先我们要构造一个 Expando 的一个对象实例，同时设置 hashCode 的实现为 MethodClosure...
