CVSS 8.3 High EPSS 94.7% · p99.9 Act now
Should you act?
High exploit likelihood
EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 94.7%, percentile 99.9: FIRST’s model estimates a 94.7% 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.
- Editorial verdict: Act now. Ivanti Connect Secure Zero-Day Chain: Unauthenticated RCE — This chain was exploited as a zero-day by a suspected nation-state actor and then mass-exploited; any unpatched appliance should be assumed compromised, not just patched.
