JBMC Software DirectAdmin before 1.334 allows local users to create or overwrite any file via a symlink attack on an arbitrary file in a certain temporary directory, related to a request for this temporary file in the PATH_INFO to the CMD_DB script during a backup action.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
