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.
-
Confirm Websense TRITON AP-EMAIL is installedCheck for the presence of Websense TRITON AP-EMAIL installation directory or look for the websense service on the system. Common paths include C:\Program Files\Websense or /opt/websense on Linux. Also check Windows Services or Linux service listings for websense-related services.Affected if Websense TRITON AP-EMAIL is installed on the system
-
Identify the installed versionLocate the version information for the installation. On Windows, check the file properties of the main executable or check the Windows Registry under HKLM\SOFTWARE\Websense\TRITON. On Linux, check /opt/websense/admin/version or similar version files in the installation directory.Affected if The installed version is 7.8.3 or lower, or if the version cannot be determined but the software is present and the service is running on port 17703
-
Verify if the service is listening on port 17703Run a network port scan or check listening ports using commands such as netstat -an | grep 17703 on Linux or netstat -ano | findstr 17703 on Windows. Alternatively, use a tool like nmap -p 17703 localhost to check if the port is open and listening.Affected if Port 17703 is open and accepting connections, indicating the vulnerable service is active
