3Com NBX ftpd CEL Command Remote Overflow (1)

This script is Copyright (C) 2002-2011 Michael Scheidell


Synopsis :

The remote FTP server is affected by a buffer overflow vulnerability.

Description :

According to its banner, the remote FTP server is a version of VxWorks
ftpd between 5.4 and 5.4.2. Such versions are known to be affected by
a buffer overflow that can be triggered with an overly-long 'CEL'
command. This problem is similar to the 'aix ftpd' overflow but on
embedded VxWorks-based systems like the 3Com NBX IP phone call manager
and seems to cause the server to crash.

Solution :

If you are using an embedded VxWorks product, please contact the OEM
vendor and reference WindRiver field patch TSR 296292. If this is the
3Com NBX IP Phone call manager, contact 3Com.
