Lifecycle Timeline
1DescriptionCVE.org
An unauthenticated remote attacker can exploit the behavior of the pathfinder TCP encapsulation service by establishing a high number of TCP connections to the pathfinder TCP encapsulation service. The impact is limited to blocking of valid IPsec VPN peers.
AnalysisAI
An unauthenticated remote attacker can exploit the behavior of the pathfinder TCP encapsulation service by establishing a high number of TCP connections to the pathfinder TCP encapsulation service. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Allocation of Resources Without Limits (CWE-770), which allows attackers to exhaust system resources through uncontrolled allocation. An unauthenticated remote attacker can exploit the behavior of the pathfinder TCP encapsulation service by establishing a high number of TCP connections to the pathfinder TCP encapsulation service. The impact is limited to blocking of valid IPsec VPN peers. Affected products include: Phoenixcontact Tc Mguard Rs4000 4G Vzw Vpn Firmware, Phoenixcontact Tc Mguard Rs4000 4G Vpn Firmware, Phoenixcontact Tc Mguard Rs4000 4G Att Vpn Firmware, Phoenixcontact Tc Mguard Rs4000 3G Vpn Firmware, Phoenixcontact Tc Mguard Rs2000 4G Vzw Vpn Firmware.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Set resource limits, implement rate limiting, validate input sizes.
