The exos 9300 application can be used to configure Access Managers (e.g.

The exos 9300 application can be used to configure Access Managers (e.g. 92xx, 9230 and 9290). The configuration is done in a graphical user interface on the dormakaba exos server. As soon as the save button is clicked in exos 9300, the whole configuration is sent to the selected Access Manager via SOAP. The SOAP request is sent without any prior authentication or authorization by default. Though authentication and authorization can be configured using IPsec for 92xx-K5 devices and mTLS for 92xx-K7 devices, it is not enabled by default and must therefore be activated with additional steps. This insecure default allows an attacker with network level access to completely control the whole environment. An attacker is for example easily able to conduct the following tasks without prior authentication: - Re-configure Access Managers (e.g. remove alarming system requirements) - Freely re-configure the inputs and outputs - Open all connected doors permanently - Open all doors for a defined time interval - Change the admin password - and many more Network level access can be gained due to an insufficient network segmentation as well as missing LAN firewalls.

What it means for a small business

If your business uses Access Manager 92xx-k5, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.65%, higher than 51% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 28, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
