http://secunia.com/advisories/37628/

DESCRIPTION:
A vulnerability has been reported in the SEIL B1 router, which can be

restrictions.

The vulnerability is caused due to the CHAP and MS-CHAP-V2
authentication processes within the PPP Access Concentrator reusing
the same challenge for each authentication request. This can be
exploited to gain access to the network by replaying the
challenge-response sequences.
