Noroxi assessment

Priority: This week (action score 62/100)

  • CISA has confirmed exploitation in the wild (Mar 4, 2025). Remediation deadline for US federal agencies: Mar 25, 2025.
  • Probability of exploitation in the next 30 days: 1.5% (FIRST EPSS); higher than 75.5% of all records.
  • Someone with local access to the system can trigger it. Administrator privileges are required. 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.

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

VMware ESXi, and Workstation contain a TOCTOU (Time-of-Check Time-of-Use) vulnerability that leads to an out-of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host.

The score given by the assigning authority versus NVD’s independent score. A gap means the severity is contested.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Mar 4, 2025. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Mar 25, 2025.
