Detailsinfo

A vulnerability classified as problematic has been found in BD FACSChorus up to 3.1/5.1. Affected is an unknown function of the component LLMNR/MBT-NS/MDNS. The manipulation with an unknown input leads to a weak hash vulnerability. CWE is classifying the issue as CWE-328. The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack). This is going to have an impact on confidentiality. CVE summarizes:

The Operating System hosting the FACSChorus application is configured to allow transmission of hashed user credentials upon user action without adequately validating the identity of the requested resource. This is possible through the use of LLMNR, MBT-NS, or MDNS and will result in NTLMv2 hashes being sent to a malicious entity position on the local network. These hashes can subsequently be attacked through brute force and cracked if a weak password is used. This attack would only apply to domain joined systems.

The weakness was published 11/29/2023. The advisory is available at bd.com. This vulnerability is traded as CVE-2023-29062 since 03/30/2023. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1600.001 by the MITRE ATT&CK project.

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