Rittal IoT Interface/CMC III Processing Unit Function Call rand generation of predictable numbers or identifiers

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability has been found in Rittal IoT Interface and CMC III Processing Unit (version now known) and classified as problematic. Affected by this vulnerability is the function rand of the component Function Call Handler. The manipulation with an unknown input leads to a generation of predictable numbers or identifiers vulnerability. The CWE definition for the vulnerability is CWE-340. The product uses a scheme that generates numbers or identifiers that are more predictable than required. As an impact it is known to affect confidentiality. The summary by CVE is:

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.

The weakness was presented by Johannes Kruchem. It is possible to read the advisory at r.sec-consult.com. This vulnerability is known as CVE-2024-47945 since 10/07/2024. The exploitation appears to be difficult. Technical details and also a public exploit are known. The attack technique deployed by this issue is T1600.001 according to MITRE ATT&CK.

It is possible to download the exploit at packetstormsecurity.com. It is declared as proof-of-concept.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
