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 LG Simple Editor is installedLocate LG Simple Editor installation directory and verify the application is present on the systemAffected if LG Simple Editor version 3.21.0 is found installed
-
Confirm installed version numberCheck the application version using its built-in about or version information feature, or inspect version metadata in installation filesAffected if Installed version equals exactly 3.21.0
-
Determine if copyContent functionality is accessibleCheck whether the copyContent command feature is enabled or exposed in the application configuration or API endpointsAffected if The copyContent command is available and accessible to unauthenticated users
-
Verify network exposureAssess whether the LG Simple Editor application is accessible from untrusted networks or directly exposed to the internetAffected if The application accepts connections from untrusted network sources without authentication
A system is affected if LG Simple Editor version 3.21.0 is installed with the copyContent functionality exposed to network access, allowing unauthenticated remote code execution.
