SNMP Version 3 Authentication Vulnerabilities (cisco-sa-20080610-snmpv3)

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote device is missing a vendor-supplied security patch.

Description :

Multiple Cisco products contain either of two authentication
vulnerabilities in the Simple Network Management Protocol version 3
(SNMPv3) feature. These vulnerabilities can be exploited when
processing a malformed SNMPv3 message. The vulnerabilities could allow
the disclosure of network information or may enable an attacker to
perform configuration changes to vulnerable devices. The SNMP server is
an optional service that is disabled by default in Cisco products. Only
SNMPv3 is impacted by these vulnerabilities. Workarounds are available
for mitigating the impact of the vulnerabilities described in this
document. Note: SNMP versions 1, 2 and 2c are not impacted by these
vulnerabilities. The United States Computer Emergency Response Team
(US-CERT) has assigned Vulnerability Note VU#878044.
