Allocation of Resources Without Limits or Throttling (CWE-770)
Summary
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.
References
Mitigation
Access to the listen port of the pathfinder TCP encapsulation service should be limited to trustworthy networks or peers.
Remediation
Phoenix Contact strongly recommends upgrading affected mGuard devices to firmware version 8.9.3 / 10.4.1 or higher which fix this vulnerability.
