Real — exploited in the wild
CISA confirms active exploitation. Treat scanner hits as true positives unless your specific version or config is unaffected.

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.

Service Location Protocol (SLP) Denial-of-Service Vulnerability — The Service Location Protocol (SLP) contains a denial-of-service (DoS) vulnerability that could allow an unauthenticated, remote attacker to register services and use spoofed UDP traffic to conduct a denial-of-service (DoS) attack with a significant amplification factor. Listed in the CISA KEV catalog (added 2023-11-08) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~66%. Treat it as real and prioritize remediation over triage.

Required action for IETF Service Location Protocol (SLP): 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. CISA set a federal remediation due date of 2023-11-29. After patching, verify the vulnerable path is no longer reachable before closing the finding.
