Noroxi assessment
Priority: This week (action score 77/100)
- CISA has confirmed exploitation in the wild (Apr 17, 2023). Remediation deadline for US federal agencies: May 8, 2023.
- Probability of exploitation in the next 30 days: 40.6% (FIRST EPSS); higher than 98.6% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- Fixed version: Microsoft Edge (Chromium-based) 112.0.1722.48.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Don’t wait for the next maintenance window. Upgrade to Microsoft Edge (Chromium-based) 112.0.1722.48 or later.
