How to check if you are exposed to CVE-2024-8963

Find every Ivanti Cloud Services Appliance (CSA) system you or your clients run, including ones exposed to the internet. Those come first: CISA only lists flaws attackers are already using.
Compare each version with the fixed versions in the vendor advisory below. Where no fix exists yet, apply the vendor’s mitigation or take the system off the internet.
Run a credentialed vulnerability scan to catch the systems you missed, then check that the next scan no longer reports CVE-2024-8963.

US federal agencies had to fix this by 2024-10-10. Everyone else should treat that deadline as a guide: if it has passed, this is overdue.
