CVE-2002-2053

CVE-2002-2053 describes a vulnerability in Cisco IOS 12.1 where the Hot Standby Routing Protocol (HSRP) implementation, in conjunction with IRPAS, can be triggered when a router uses the same IP address as the HSRP interface. An attacker remotely induces a DoS by causing CPU consumption and a rou...

CVE-2002-2053: Undefined Security Weakness

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...

CVE-2002-1768

Cisco IOS versions 11.1–12.2 are affected when HSRP support is not enabled. The issue allows an attacker to cause a denial of service (CPU consumption) by sending randomly sized UDP packets to the HSRP port 1985. The Nessus plugin CISCO-20020606-HSRP.NASL confirms this condition and notes that th...

CVE-2001-0741

CVE-2001-0741 covers a vulnerability in Cisco’s Hot Standby Router Protocol (HSRP) where an attacker on the same LAN can spoof HSRP packets to disrupt traffic, causing a denial of service. The CERT CERT/CC advisory notes a workaround of using HSRP with IPsec; Cisco’s own entry confirms the vulner...

Cisco HSRP Weakness/DoS

Hi I was playing with Cisco's HSRP Hot Standby Routing Protocol, and there is a major weakness in that protocol that allow any host in a LAN segment to make a HSRP DoS. Short very explain of HSRP. HSRP uses UDP on port 1985 to multicast address 224.0.0.2, and the authentication is in clear text...
