Cisco IOS 12.2, 12.4, 15.0, 15.2, and 15.3 allows remote attackers to cause a denial of service (device reload) via malformed Common Industrial Protocol (CIP) TCP packets, aka Bug ID CSCun63514.

Security readout for executives and security teams

This flaw can let a remote attacker crash and reload affected Cisco IOS devices by sending malformed CIP TCP traffic. The direct impact is service interruption, not confirmed data theft or code execution. It matters most where Cisco IOS devices support industrial or operational networks and a reload would disrupt production, safety monitoring, or site connectivity. Exposure is most likely on Cisco IOS routers or switches running the listed IOS trains with CIP TCP handling reachable from untrusted, partner, industrial, or poorly segmented networks. The provided CVE data does not identify specific platforms or configurations beyond Cisco IOS versions and CIP traffic. Handle as a resilience risk for industrial and operational networks. It is not evidenced as actively exploited here, but a remotely triggerable device reload can create meaningful downtime. Prioritize exposed or critical Cisco IOS assets before lower-impact internal devices. Mitigation focus: Check Cisco advisory cisco-sa-20150325-cip for fixed IOS releases and upgrade guidance.; Prioritize devices where a reload would affect industrial operations or critical connectivity.; Restrict CIP TCP reachability to required trusted network paths only..
