VAR-201310-0530
Vulnerability from variot - Updated: 2023-12-18 12:38Cisco IOS XE 3.9 before 3.9.2S on 1000 ASR devices allows remote attackers to cause a denial of service (device reload) by sending malformed EoGRE packets over (1) IPv4 or (2) IPv6, aka Bug ID CSCuf08269. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. The attacker failed to properly handle malformed EoGRE packets. The attacker exploited this vulnerability by sending malformed IPv4 or IPv6 EoGRE packets to affected devices configured with the EoGRE interface. Successful exploits may allow an attackers to cause a reload of the affected devices, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCuf08269
