Detailsinfo

A vulnerability was found in Service Location Protocol. It has been classified as critical. Affected is an unknown code block. The manipulation with an unknown input leads to a denial of service vulnerability (Amplification). CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. CVE summarizes:

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.

The weakness was published 04/25/2023. The advisory is shared for download at bitsight.com. This vulnerability is traded as CVE-2023-29552 since 04/07/2023. Technical details are unknown but an exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 01/29/2025). The MITRE ATT&CK project declares the attack technique as T1499. This vulnerability has a historic impact due to its background and reception.

It is declared as attacked. This issue was added on 11/08/2023 to the CISA Known Exploited Vulnerabilities Catalog with a due date of 11/29/2023:

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.

It is possible to mitigate the problem by applying the configuration setting Disable SLP.It is possible to mitigate the weakness by firewalling udp/427. The best possible mitigation is suggested to be applying a restrictive firewalling.
