Cisco IOS XE Software Resource Reservation Protocol Interface Queue Wedge Vulnerability (cisco-sa-20130925-rsvp)

high Nessus Plugin ID 70312

Language:

Synopsis

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

Description

A vulnerability in the Resource Reservation Protocol (RSVP) feature of Cisco IOS XE Software allows an unauthenticated, remote attacker to trigger an interface queue wedge on the affected device. The vulnerability is due to improper parsing of UDP RSVP packets. An attacker can exploit this vulnerability by sending UDP port 1698 RSVP packets to the vulnerable device. An exploit can cause Cisco IOS XE software to incorrectly process incoming packets, resulting in an interface queue wedge, which can lead to loss of connectivity, loss of routing protocol adjacency, and other denial of service (DoS) conditions. Cisco has released free software updates that address this vulnerability. Workarounds that mitigate this vulnerability are available.

Note that this plugin checks for an affected IOS XE version and does not attempt to perform any additional validity checks.

Solution

Apply the relevant patch referenced in Cisco security advisory cisco-sa-20130925-rsvp.
