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 SysAid SysAid Server. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2023-11-13, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2023-12-04; treat that as the outer limit, not the target. CISA also lists it as known to be used in ransomware campaigns.
- EPSS 98.9%, percentile 99.9: FIRST’s model estimates a 98.9% chance of exploitation activity in the next 30 days, higher than 99.9% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
