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 Ivanti Cloud Services Appliance (CSA). CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-09-19, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-10-10; treat that as the outer limit, not the target.
  • EPSS 98.6%, percentile 99.9: FIRST’s model estimates a 98.6% 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.
