For Symmetricom SyncServer S300 version 2.65.0, consider disabling the "syslog.php" endpoint as a temporary workaround until a patch is available. For Symmetricom SyncServer S350 version 2.80.1, limit the use of the FileName parameter in the "syslog.php" endpoint to prevent potential directory traversal attacks.
