Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, IOS is affected by a denial of service (DoS) vulnerability in its Internet Key Exchange (IKE) version 2 implementation due incorrect handling of IKEv2 SA-Init packets. An unauthenticated, remote attacker can exploit this issue, by sending specially crafted IKEv2 SA-Inet packets to an affected host, to cause a DoS condition.

Please see the included Cisco BIDs and Cisco Security Advisory for more information. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCvp44397
