|漏洞详情
PHP是广泛使用的通用目的脚本语言,特别适合于Web开发,可嵌入到HTML中。PHP中存在远程溢出漏洞,攻击者可以利用这个漏洞在受影响的WebServer上执行任意代码。失败的攻击尝试也可能导致WebServer崩溃。请注意通常情况下远程攻击者是无法修改访问mysql_connect函数的参数的,因此可限制攻击的可能性。

/*
This exploit was designed to work with PHP versions 4.3.10 and
4.4.0 under Windows XP SP 1. If another operating system is used,
the replacement EIP must be changed.

The replacement EIP is written 261 bytes into our string. For this
exploit, I used a CALL ESI from ws2_32.dll from Windows XP SP1.

The replacement ESI is simply the base of the PHP image. Locations
after this address will be overwritten with some internal data.

Our shellcode is written into the $user variable. $two is used to
prevent $user from being truncated with a MySQL error message.
