Ingate Firewall/SIParator Packet Filter Rule Bypass Vulnerability

Ingate Firewall/SIParator products have been reported prone to a TCP packet filter bypass vulnerability under some circumstances.

The issue presents itself if TCP packet filtering is being used in the affected software. A malicious packet containing certain set flags that passes through the firewall in the reply direction, may bypass packet-filtering rules on the affected firewall.
