Cisco IOS Software Processing of SAA Packets - Cisco Systems

This script is (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

The remote device is missing a vendor-supplied security patch

Description :

The Service Assurance Agent (SAA) is the new name for the Response Time
Reporter (RTR) feature.
The router is vulnerable only if the RTR responder is enabled. When the
router receives a malformed RTR packet, it will crash. RTR is disabled
by default.
There is no workaround short of disabling the RTR responder. It is
possible to mitigate the vulnerability by applying the access control
list (ACL) on the router.
