Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Ivanti Secure Access Client is installedCheck for the presence of Ivanti Secure Access Client on the system. On Windows, look for the installation directory (typically in Program Files or Program Files (x86)\Ivanti) or check Add/Remove Programs. On Linux, check /opt/ivanti or use package management tools.Affected if The product is installed on the system
-
Identify the installed versionLocate and read the version information. On Windows, right-click the Ivanti Secure Access Client executable (isa.exe or similar) and select Properties, then check the Details tab for the File Version. On Linux, run 'iva --version' or check /opt/ivanti/etc/version if available.Affected if Unable to determine the version from the installed product
-
Compare version against affected rangesCompare the installed version number to the affected ranges: versions lower than 22.7, or exactly version 22.7 (all 22.7.x variants before R3). Versions 22.7R3 and later are NOT affected.Affected if Installed version is less than 22.7 OR installed version is exactly 22.7 (any 22.7.x build before R3)
-
Confirm the client service is runningCheck if the Ivanti Secure Access Client service or daemon is active. On Windows, open Services and look for 'Ivanti Secure Access Client' or check Task Manager for related processes. On Linux, run 'ps aux | grep ivanti' or check systemctl status.Affected if The client service is running and version is in the affected range
A system is affected if Ivanti Secure Access Client is installed with a version less than 22.7 or equal to 22.7 (any 22.7.x build before R3), regardless of whether the service is currently running.
