				This module abuses two flaws - a metacharacter injection vulnerability in the
				HTTP management server of RedHat 6.2 systems running the Piranha
				LVS cluster service and GUI (rpm packages: piranha and piranha-gui).
				The vulnerability allows an authenticated attacker to execute arbitrary
				commands as the Apache user account (nobody) within the
				/piranha/secure/passwd.php3 script. The package installs with a default
				user and password of piranha:q which was exploited in the wild.
