CVE-2024-47945 (GCVE-0-2024-47945)
Vulnerability from nvd – Published: 2024-10-15 10:05 – Updated: 2025-11-03 22:21
VLAI
Title
Predictable Session ID
Summary
The devices are vulnerable to session hijacking due to insufficient
entropy in its session ID generation algorithm. The session IDs are
predictable, with only 32,768 possible values per user, which allows
attackers to pre-generate valid session IDs, leading to unauthorized
access to user sessions. This is not only due to the use of an
(insecure) rand() function call but also because of missing
initialization via srand(). As a result only the PIDs are effectively
used as seed.

CVE-2024-47943 (GCVE-0-2024-47943)
Vulnerability from nvd – Published: 2024-10-15 08:57 – Updated: 2025-11-03 22:21

Title
Improper signature verification of firmware upgrade files
Summary
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.

CVE-2024-47945 (GCVE-0-2024-47945)
Vulnerability from cvelistv5 – Published: 2024-10-15 10:05 – Updated: 2025-11-03 22:21

Title
Predictable Session ID
Summary
The devices are vulnerable to session hijacking due to insufficient
entropy in its session ID generation algorithm. The session IDs are
predictable, with only 32,768 possible values per user, which allows
attackers to pre-generate valid session IDs, leading to unauthorized
access to user sessions. This is not only due to the use of an
(insecure) rand() function call but also because of missing
initialization via srand(). As a result only the PIDs are effectively
used as seed.

Title
Improper signature verification of firmware upgrade files
Summary
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.
