The Protocol Translation (PT) functionality in Cisco IOS 12.3 through 12.4 and 15.0 through 15.3, when one-step port-23 translation or a Telnet-to-PAD ruleset is configured, does not properly validate TCP connection information, which allows remote attackers to cause a denial of service (device reload) via an attempted connection to a PT resource, aka Bug ID CSCtz35999.

Security readout for executives and security teams

Cisco IOS devices using specific Protocol Translation configurations could reload when a remote connection is attempted to a PT resource. That means a network device may temporarily stop forwarding traffic. The evidence provided describes denial of service only, not data theft or code execution. Exposure appears limited to Cisco IOS devices running the listed trains with Protocol Translation configured for port-23 one-step translation or Telnet-to-PAD rulesets. Devices without those PT configurations are not shown as affected by the provided evidence. Treat this as a targeted availability risk for legacy Cisco IOS infrastructure. Prioritize internet-facing or partner-reachable devices that use Protocol Translation, especially where reloads would disrupt routing, remote access, or critical network segments. Mitigation focus: Review Cisco advisory cisco-sa-20130327-pt for fixed releases and official workarounds.; Inventory Cisco IOS 12.3, 12.4, 15.0, 15.1, 15.2, and 15.3 devices.; Identify and remove unused Protocol Translation rulesets where operationally safe..
