Description
The Axel Technology puma devices (firmware versions 0.8.5 to 1.0.3) are vulnerable to Broken Access Control due to missing authentication on the /cgi-bin/gstFcgi.fcgi endpoint. Unauthenticated remote attackers can list user accounts, create new administrative users, delete users, and modify system settings, leading to full compromise of the device.
