CVE-2024-49117: Windows Hyper-V Remote Code Execution Vulnerability

Noroxi assessment

Priority: Monitor (action score 35/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1% (FIRST EPSS); higher than 63.6% 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.
  • Fixed version: Windows 11 Version 22H2 for ARM64-based Systems 10.0.22621.4602; Windows 11 Version 22H2 for x64-based Systems 10.0.22621.4602; Windows 11 Version 23H2 for ARM64-based Systems 10.0.22631.4602.

Low priority for now. Upgrade to Windows 11 Version 22H2 for ARM64-based Systems 10.0.22621.4602; Windows 11 Version 22H2 for x64-based Systems 10.0.22621.4602; Windows 11 Version 23H2 for ARM64-based Systems 10.0.22631.4602 or later.

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.
