VAR-201509-0283
Vulnerability from variot - Updated: 2025-04-13 23:39The IPv4 implementation on Cisco ASR 1000 devices with software 15.5(3)S allows remote attackers to cause a denial of service (ESP QFP CPU consumption) by triggering packet fragmentation and reassembly, aka Bug ID CSCuv71273. The Cisco ASR1000 Series Aggregation Services Router provides a WAN edge solution that combines information, communications, collaboration and business. The Cisco ASR 1000 Series Router has a security vulnerability in the processing of 100,000 fragmented IPv4 packets. This allows a remote attacker to exploit a vulnerability to send a special packet to make the target device QFP CPU resource too high, causing a denial of service attack. An attacker can exploit this issue to consume CPU resources and cause a denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCuv71273
