Bender is publishing this advisory to inform customers about multiple security vulnerabilities in the Charge Controller product families.
Bender has analysed the weaknesses and determined that the electrical safety of the devices is not concerned. To Benders knowledge, proof-of-concept code or exploits for the weaknesses are not available to the public.
Bender considers some weaknesses to be critical and thus need to be patched immediately. Therefore, patches are provided as maintenance branch versions 5.11.2, 5.12.5, 5.13.2 and 5.20.2. Future software releases will of course already include these patches.
Bender is publishing this advisory to inform customers about a security vulnerability in all devices running the COMTRAXX software.
The user authorization is validated for most, but not all routes in the system. A user with knowledge about the routes can read and write configuration data without prior authorization.
