Cisco CatOS VACM read-write Community String Device Configuration Manipulation

This script is Copyright (C) 2001-2012 Tenable Network Security, Inc.


Synopsis :

The SNMP private community strings can be retrieved using SNMP.

Description :

It is possible to obtain the remote private community strings using
the View-Based Access Control MIB (VACM) of the remote Cisco router.
An attacker may use this flaw to gain read/write SNMP access on this
router.

Note that a value in this table does not necessarily mean that an
instance with the value exists in table vacmAccessTable. The SNMP
private community string(s) returned may only allow read access.

Solution :

Disable the SNMP service on the remote host if you do not use it, or
filter incoming UDP packets going to this port or install Cisco patch.
