CVE-2023-29552· NVD / CVE Program· CNA mitre

The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, remote attacker to register arbitrary services.

Noroxi assessment

Priority: This week (action score 79/100)

  • CISA has confirmed exploitation in the wild (Nov 8, 2023). Remediation deadline for US federal agencies: Nov 29, 2023.
  • Probability of exploitation in the next 30 days: 63.9% (FIRST EPSS); higher than 99.2% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • According to the record, no fixed version is available yet.

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

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.

Vulnrichment: CISA's decision-tree inputs.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Nov 8, 2023. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Nov 29, 2023.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
