The AFS fileserver typically listens on UDP port 7000. Use firewalls to restrict access to this port only to known client IP ranges. This limits the "blast radius" by preventing external, unauthenticated attackers from reaching the fileserver. 4. Monitor Server Logs
When a client sends an oversized UUID blob in a malformed packet:
The exploit was particularly serious because AFS was widely used in academic and research environments, where sensitive data was often stored on file servers. The vulnerability was also relatively easy to exploit, as attackers could use publicly available tools to craft the malicious protocol packets.
