Detailsinfo

A vulnerability, which was classified as very critical, was found in Dormakaba Access Manager 92xx-k5 (unknown version). Affected is an unknown code block of the component SSH Service. The manipulation with an unknown input leads to a weak credentials vulnerability. CWE is classifying the issue as CWE-1391. The product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The Access Manager 92xx in hardware revision K7 is based on Linux instead of Windows CE embedded in older hardware revisions. In this new hardware revision it was noticed that an SSH service is exposed on port 22. By analyzing the firmware of the devices, it was noticed that there are two users with hardcoded and weak passwords that can be used to access the devices via SSH. The passwords can be also guessed very easily. The password of at least one user is set to a random value after the first deployment, with the restriction that the password is only randomized if the configured date is prior to 2022. Therefore, under certain circumstances, the passwords are not randomized. For example, if the clock is never set on the device, the battery of the clock module has been changed, the Access Manager has been factory reset and has not received a time yet.

The weakness was presented by Clemens Stockenreitner and Werner Schober. The advisory is available at r.sec-consult.com. This vulnerability is traded as CVE-2025-59103 since 09/09/2025. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 01/26/2026).

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