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 Tegsoft Online Support Application installationSearch for Tegsoft installation directories or check running services/processes for 'tegsoft' or 'online support' componentsAffected if Tegsoft Online Support Application is not installed on the system
-
Determine installed versionCheck the application's version information through its admin interface, configuration files, or installation metadataAffected if Version falls within V3 through 31122025 range
-
Compare version to affected rangeParse the version number and compare against V3 (minimum) and 31122025 (maximum)Affected if Installed version is V3 or higher, or is 31122025 or lower, meaning it falls within or overlaps the affected range
-
Verify web interface exposureIdentify if the Online Support Application web interface is accessible externally or to untrusted usersAffected if Web interface is exposed to users or attackers who can craft malicious URLs
-
Identify input handling in web pagesReview web application traffic or logs for user-supplied parameters that get reflected in responses without encodingAffected if Application reflects user input in web page responses without visible sanitization
User is affected if Tegsoft Online Support Application version V3 through 31122025 is installed and its web interface is accessible to users who can trigger reflected XSS through unsanitized input parameters.
