DESCRIPTION:
A weakness has been reported in Symantec Backup Exec products, which
can be exploited by malicious people to bypass certain security
restrictions.

The weakness is caused due to the communication protocol in the media
server not properly verifying the identity of the remote agent before
performing certain actions. This can be exploited to e.g. execute
post authentication NDMP commands via Man-in-the-Middle (MitM)
attacks.

The weakness is reported in the following products:
* Symantec Backup Exec for Windows Servers versions 11.0, 12.0, and
12.5.
* Symantec Backup Exec 2010 versions 13.0 and 13.0 R2

SOLUTION:
Update or upgrade to Symantec Backup Exec 2010 R3.
