CVE-2023-29552
Published: 24 April 2023
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.
Notes
| Author | Note |
|---|---|
| sbeattie | The SLP protocol was never meant to be made available to the public Internet, as the RFC 2165 authors recognize: "Service Location provides a dynamic configuration mechanism for applications in local area networks. It is not a global resolution system for the entire Internet; rather it is intended to serve enterprise networks with shared services." |
