Security News > 2020 > November > High-Severity Cisco DoS Flaw Can Immobilize ASR Routers

A high-severity flaw in Cisco's IOS XR software could allow unauthenticated, remote attackers to cripple Cisco Aggregation Services Routers.

The flaw stems from Cisco IOS XR, a train of Cisco Systems' widely deployed Internetworking Operating System.

The OS powers the Cisco ASR 9000 series, which are fully distributed routers engineered to address massive surges in video traffic.

This vulnerability affects Cisco ASR 9000 series routers if they are running a Cisco IOS XR Software release earlier than releases 6.7.2 or 7.1.2.

Cisco also recently sent out an advisory warning that a flaw the Cisco Discovery Protocol implementation for Cisco IOS XR Software was being actively exploited by attackers.
