# CVE-2024-38014: Microsoft Windows Installer Improper Privilege Management Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Microsoft Windows. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-09-10, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-10-01 ; treat that as the outer limit, not the target.
- EPSS 6.3% , percentile 94: FIRST’s model estimates a 6.3% chance of exploitation activity in the next 30 days, higher than 94% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
