CVE-1999-1066

Summary

CVE-1999-1066 is a vulnerability affecting Quake 1 servers. Malicious actors can exploit this issue by spoofing UDP game connection requests to the server, causing it to respond with excessive traffic. This traffic can then be amplified and used in "Smurf" attacks, targeting other hosts and potentially overwhelming their networks with unwanted data. The Quake 1 server unwittingly becomes an unwanted participant in such attacks, amplifying the impact of the traffic. To mitigate this risk, administrators should ensure their Quake 1 servers are updated or consider disabling them if no longer required.
