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 if Websense TRITON AP-EMAIL is installedCheck the system for Websense TRITON AP-EMAIL installation directories, services, or registry entries related to Websense email security products. Look for 'Websense' or 'TRITON' in installed programs or running services.Affected if Websense TRITON AP-EMAIL version 7.8.3 or earlier is found on the system
-
Determine the installed version of TRITON AP-EMAILLocate and examine the product's version information. This is typically found in the product's About section, installation directory files, or the Windows Registry under the Websense product keys. Compare the version number against the affected range.Affected if The installed version is 7.8.3 or any earlier version (versions prior to 8.0.0)
-
Verify if Personal Email Manager (PEM) component is enabledAccess the TRITON AP-EMAIL administrative console or configuration settings. Navigate to the Personal Email Manager module or feature list to confirm whether PEM is currently enabled and accessible to end users.Affected if The PEM component is enabled and accessible to users (the vulnerability exists in this component)
-
Check for unusual failed authentication patternsReview authentication logs, security event logs, or TRITON AP-EMAIL access logs for signs of repeated failed login attempts originating from the same source IP address, which would indicate the brute force vulnerability is being exploited.Affected if Logs show repeated failed login attempts against email accounts without account lockout or significant throttling
The environment is affected if Websense TRITON AP-EMAIL version 7.8.3 or earlier is installed with the Personal Email Manager component enabled and accessible.
