CVE-2004-2597 is a vulnerability of currently unknown severity. Quake II server before R1Q2, as used in multiple products, allows remote attackers to bypass IP-based access control rules via a userinfo string that already contains an "ip" key/value pair but is also long enough to cause a new key/value pair to be truncated, which interferes with the server's ability to find the client's IP address.. EPSS estimates a 1.65% chance of exploitation in the next 30 days.
