Name of the Vulnerable Software and Affected Versions TerraMaster TOS versions 4.2.06 and earlier

Description The issue allows remote authenticated attackers to read, edit, or delete any file within the filesystem. This can be achieved via the filename parameter to "/tos/index.php?editor/fileGet", Event parameter to "/include/ajax/logtable.php", or opt parameter to "/include/core/index.php".

Recommendations For TerraMaster TOS versions 4.2.06 and earlier, as a temporary workaround, consider restricting access to the vulnerable API endpoints "/tos/index.php?editor/fileGet", "/include/ajax/logtable.php", and "/include/core/index.php" until a patch is available. Avoid using the filename, Event, and opt parameters in the affected API endpoints until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
