Improper
neutralization of path traversal sequences in TeamViewer Desktop Clients prior
Version 15.81.5 allows an authenticated remote session participant to write files
to unintended locations on the local file system via file transfer or virtual
file clipboard mechanisms. An attacker can leverage this behavior to achieve
arbitrary file write and potentially execute code with the privileges of the
affected user.
