<p>SIMATIC HMI Unified Comfort Panels before V21.0 are affected by a
vulnerability that allows an unauthenticated attacker to access the web
browser via the help link. This vulnerability allows an attacker to
access the web browser through the Control Panel if it is not protected
by the corresponding security mechanisms. This opens the possibility for
the attacker to find backdoors, which might lead to unwanted
misconfigurations.</p>
<p>Siemens has released new versions for the affected products and
recommends to update to the latest versions.</p>
