PHP 5.3.4(WIN) COM_SINK权限提升漏洞

admin

PHP最新版已经更新至5.4.x，不过中国大陆尚处于在5.2.x和5.3.x更替的阶段。存在漏洞的php存在于5.3.x版本中

测试方法如下：cmd /c x:\php\php.exe x:\test.php

! ~: {" }; T+ H/ Z8 V) g7 m下载php程序至本地，然后使用php.exe解析php即可。Webshell上面使用php的exec等函数执行，或者使用Wscript.shell调用cmd.exe然后 /c x:\php\php.exe x:\xxxx\test.php

关于漏洞分析稍后附上。一下是PoC代码：
