This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
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.
