Unspecified vulnerability in the SIP module in InGate Firewall and SIParator before 4.5.1 allows remote attackers to conduct replay attacks on the authentication mechanism via unknown vectors.
Ingate Firewall before 4.6.0 and SIParator before 4.6.0 do not log truncated (1) ICMP, (2) UDP, and (3) TCP packets, which has unknown impact and remote attack vectors; and do not log (4) serial-console login attempts with nonexistent usernames, which might make it easier for attackers with physical access to guess valid login credentials while avoiding detection.
