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 installed IBM Aspera Shares versionCheck the product version through the admin interface, or look for version information in installation files, about page, or product documentationAffected if Version cannot be determined or is not visible
-
Compare version against affected rangeDetermine if the installed version is >= 1.9.9 and < 1.11.1Affected if Installed version falls within 1.9.9 to 1.11.0 inclusive
-
Verify web interface is accessibleConfirm the Aspera Shares web interface is exposed and reachableAffected if Web interface is publicly or internally accessible and version is in affected range
-
Check for recent security patchesLook for any applied patches or hotfixes related to input sanitization in the systemAffected if No vendor patches for input validation have been applied and version is affected
The environment is affected if IBM Aspera Shares is installed with a version between 1.9.9 and 1.11.0 inclusive and the web interface is accessible.
