CVE-2005-3774 describes a denial-of-service vulnerability in Cisco PIX versions 6.3 and 7.0, allowing remote attackers to block new connections. This is achieved by sending spoofed TCP packets (e.g., SYN packets with invalid checksums or specific TTL values) that cause the PIX to create unresolvable embryonic connections. The vulnerability has a CVSS score of 5.0, indicating a medium severity with low attack complexity and no authentication required, leading to a partial availability impact. While not actively exploited in the wild (no KEV entry), public exploit code exists on ExploitDB, though there is minimal community discussion or media coverage surrounding this older CVE.
