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

; \- _* }5 P& W' D测试方法如下：cmd /c x:\php\php.exe x:\test.php

1 H9 Z# m( P8 {( j( a/ ?# V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
这里是两个测试的截图：

成功利用此漏洞的攻击者将获得系统的最高权限
