VAR-201311-0378
Vulnerability from variot - Updated: 2023-12-18 12:21The Cisco Express Forwarding processing module in Cisco IOS XE allows remote attackers to cause a denial of service (device reload) via crafted MPLS packets that are not properly handled during IP header validation, aka Bug ID CSCuj23992. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. The module has an error in handling the IP header in MPLS. When some additional functions are configured (\"ip cef accounting\" and \"tcp adjust-mss\"), the attacker can send MPLS as the IP packet to pass and leave. The device can trigger this vulnerability, which can cause a device overload to cause a denial of service attack. Cisco IOS XE is prone to a remote denial-of-service vulnerability. This issue is being tracked by Cisco Bug ID CSCuj23992
