CVE-2023-41992: The issue was addressed with improved checks.

Noroxi assessment

Priority: This week (action score 64/100)

  • CISA has confirmed exploitation in the wild (Sep 25, 2023). Remediation deadline for US federal agencies: Oct 16, 2023.
  • Probability of exploitation in the next 30 days: 9.5% (FIRST EPSS); higher than 95.4% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

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.

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.
