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.
-
Identify Acronis Cyber Protect 17 installationLocate the Acronis Cyber Protect 17 installation on the system. On Windows, check Program Files/Acronis directory or look for the Acronis service. On Linux, check /usr/lib/Acronis or /opt/Acronis directories.Affected if Acronis Cyber Protect 17 is installed on the system
-
Determine the installed build numberUse the product's built-in version information utility or check the product's About/Status interface to retrieve the exact build number of the installed Acronis Cyber Protect 17 instance.Affected if The build number is lower than 41186 (e.g., 41185 or earlier)
-
Verify the operating system platformConfirm whether the affected Acronis Cyber Protect 17 is running on Linux, Windows, or both.Affected if The product is running on either Linux or Windows with a build below 41186
The environment is affected if Acronis Cyber Protect 17 is installed with a build number lower than 41186 on either Linux or Windows platform.
