Access Manager 92xx-k5: Reliance on IP Address for Authentication

CVE-2025-59101 is a high-severity reliance on IP address for authentication vulnerability in Access Manager 92xx-k5 from Dormakaba, with a CVSS 4.0 base score of 7.7 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected Access Manager 92xx-k5 versions: 92xx-K5: <XAMB 04.06.212. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.75% chance of exploitation within 30 days, higher than 56% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Check which version of Access Manager 92xx-k5 you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on dormakabagroup.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  4. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

Instead of typical session tokens or cookies, it is verified on a per-request basis if the originating IP address has once successfully logged in. As soon as an authentication request from a certain source IP is successful, the IP address is handled as authenticated. No other session information is stored. Therefore, it is possible to spoof the IP address of a logged-in user to gain access to the Access Manager web interface.

The underlying weakness: Reliance on IP Address for Authentication

The product uses an IP address for authentication.

How developers prevent this class of flaw

  • Use other means of identity verification that cannot be simply spoofed. Possibilities include a username/password or certificate. While IP address verification can be a useful part of an authentication scheme, but it should not be the single factor required for authentication.
