Last modified

CVE-2002-2053 is a vulnerability of currently unknown severity. The design of the Hot Standby Routing Protocol (HSRP), as implemented on Cisco IOS 12.1, when using IRPAS, allows remote attackers to cause a denial of service (CPU consumption) via a router with the same IP address as the interface on which HSRP is running, which causes a loop.. EPSS estimates a 1.59% chance of exploitation in the next 30 days.
