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 Symantec Endpoint Protection Manager is installedCheck for SEPM installation on the system. On Windows, look for the installation directory (typically in Program Files or Program Files (x86)) or check Windows Services for 'Symantec Endpoint Protection Manager' service.Affected if SEPM is found installed on the system
-
Determine the installed SEPM versionCheck the version of the installed Symantec Endpoint Protection Manager. On Windows, this may be available in Add/Remove Programs, the SEPM console (About section), or by querying the SEPM server configuration.Affected if The version is 12.1 or earlier, specifically any version before 12.1-RU6-MP3
-
Verify the management interface is accessibleDetermine if the SEPM management console port (default TCP port 8443 or 443) is listening and accessible from the network. Use netstat or similar tool to check for listening SEPM-related services.Affected if The management interface port is open and reachable from network locations (beyond localhost)
-
Confirm the vulnerable configurationThe vulnerability exists in the SEPM management interface itself. If SEPM 12.1 before RU6-MP3 is running with its management interface exposed, the system is vulnerable to command injection via crafted data.Affected if SEPM version is 12.1 before 12.1-RU6-MP3 AND the management interface is accessible
The environment is affected if Symantec Endpoint Protection Manager version 12.1 through 12.1-RU6-MP2 is installed with the management interface accessible, as this version range contains the command injection flaw in the management interface.
