Service Location Protocol (SLP) Denial-of-Service Vulnerability
Exploited in the wild
This vulnerability is on a Known Exploited Vulnerabilities catalogue, added 2023-11-08. Federal due date: 2023-11-29.
Apply mitigations per vendor instructions or disable SLP service or port 427/UDP on all systems running on untrusted networks, including those directly connected to the Internet.
Impact
The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, remote attacker to register arbitrary services. This could allow the attacker to use spoofed UDP traffic to conduct a denial-of-service attack with a significant amplification factor.
