Detailsinfo

A vulnerability was found in Rittal IoT Interface and CMC III Processing Unit. It has been declared as critical. Affected by this vulnerability is an unknown function of the component Firmware Upgrade Handler. The manipulation with an unknown input leads to a missing protection mechanism for alternate hardware interface vulnerability. The CWE definition for the vulnerability is CWE-1299. The lack of protections on alternate paths to access control-protected assets (such as unprotected shadow registers and other external facing unguarded interfaces) allows an attacker to bypass existing protections to the asset that are only performed against the primary path. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The device directly executes .patch firmware upgrade files on a USB stick without any prior authentication in the admin interface. This leads to an unauthenticated code execution via the firmware upgrade function.

The weakness was disclosed by Johannes Kruchem. The advisory is shared at r.sec-consult.com. This vulnerability is known as CVE-2024-47944 since 10/07/2024. The exploitation appears to be difficult. An attack has to be approached locally. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available.

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

Upgrading to version 6.21.00.2 eliminates this vulnerability.
