Should you act?
Exploited: patch now if you run it
CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Yes, if you run VMware vCenter Server. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-07-17, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-08-07; treat that as the outer limit, not the target.
- EPSS 13.3%, percentile 96: FIRST’s model estimates a 13.3% chance of exploitation activity in the next 30 days, higher than 96% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
