PhpMyFAQ 1.5.1 remote commands execution

PhpMyFaq 1.5.1 (possibly prior versions) is vulnerable to a remote shell injection vulnerability. This vulnerability allows an attacker to inject arbitrary commands and execute them on the vulnerable system. To exploit this vulnerability, the attacker must have access to the vulnerable system and must have the ability to modify the php.ini file. The attacker must also have the ability to launch the script from Apache. Once the script is launched, the attacker can fill in the requested fields and if magic_quotes_gpc is off, the attacker can launch commands.

Mitigation:

To mitigate this vulnerability, the user must ensure that the php.ini file is configured correctly and that the script is launched from Apache. Additionally, the user must ensure that magic_quotes_gpc is enabled.
