Cisco IOS Software Integrated Services Routers Generation 2 denial of service (cisco-sa-20170927-rbip-dos)

High Nessus Plugin ID 103671


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


According to its self-reported version and configuration, the Cisco IOS software running on the remote device is affected by a denial of service vulnerability in it's handling of ethernet frames. An unauthenticated, remote attacker can exploit this, via a specially crafted ethernet frame, to cause the switch to stop processing traffic, requiring a device restart to regain functionality.
