> PROBLEM:
>
> The PATROL management software from BMC SOFTWARE has 3 severe bugs :
>
> 1) Session password encryption weakness :
>
> The Patrol session password is protected in a way which does not prevent
>
> from replay attacks. It is possible for an attacker to capture (wire
> tapping, network sniffing...) an encrypted password and to provide it to
> the
> BMC API to connect to the agent. The attacker can then get a shell with
> the
> agent without the administrator to know it.
>
> 2) Patrol frames sealing :
>
> The algorithm used in Patrol for sealing the frames exchanged is fairly
> weak
> (enhanced checksum). It is thus quite easy for an attacker to build a
> spoofing system which sends faked frames to an agent.
>
> 3) Service deny on UDP port :
>
> The UDP ports accept connexion requests and are thus exposed to
> ping-pong
> from another UDP port (e.g. chargen).
