This signature detects attempts to exploit a known vulnerability against mod_php in Apache. Attackers can send a maliciously crafted HTTP POST request to execute arbitrary code on the affected server.
PHP is a widely deployed scripting language, designed for web based development and CGI programming. PHP does not perform proper bounds checking on in functions related to Form-based File Uploads in HTML (RFC1867). Specifically, this problem occurs in the functions which are used to decode MIME encoded files. As a result, it may be possible to overrun the buffer used for the vulnerable functions to cause arbitrary attacker-supplied instructions to be executed. PHP is invoked through webservers remotely. It may be possible for remote attackers to execute this vulnerability to gain access to target systems. A vulnerable PHP interpreter module is available for Apache servers that is often enabled by default.
