CVE-2024-47943

EUVD-2024-42735
The firmware upgrade function in the admin web interface of the Rittal IoT Interface & CMC III Processing Unit devices checks if 
the patch files are signed before executing the containing run.sh 
script. The signing process is kind of an HMAC with a long string as key
 which is hard-coded in the firmware and is freely available for 
download. This allows crafting malicious "signed" .patch files in order 
to compromise the device and execute arbitrary code.
