VAR-201405-0357
Vulnerability from variot - Updated: 2025-04-13 23:39The Locator/ID Separation Protocol (LISP) implementation in Cisco IOS 15.3(3)S and earlier and IOS XE does not properly validate parameters in ITR control messages, which allows remote attackers to cause a denial of service (CEF outage and packet drops) via malformed messages, aka Bug ID CSCun73782. Vendors have confirmed this vulnerability Bug ID CSCun73782 It is released as.Service disruption by a third party via a malformed message (CEF Stop and packet drop ) There is a possibility of being put into a state. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. Cisco IOS/OS XE has a security vulnerability in handling LISP control messages. An attacker can exploit this issue to cause an affected device to disable, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCun73782
