Dormakaba Saflok System 6000 contains a predictable key generation algorithm that allows attackers to derive card access keys from a 32-bit unique identifier. Attackers can exploit the deterministic key generation process by calculating valid access keys using a simple…

By default, the password for the Access Manager's web interface, is set to 'admin'. In the tested version changing the password was not enforced.

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…

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…

The binary serving the web server and executing basically all actions launched from the Web UI is running with root privileges. This is against the least privilege principle. If an attacker is able to execute code on the system via other vulnerabilities it is possible to…

The Access Manager is using the open source web server CompactWebServer written in C#. This web server is affected by a path traversal vulnerability, which allows an attacker to directly access files via simple GET requests without prior authentication. Hence, it is possible…

The Access Manager is offering a trace functionality to debug errors and issues with the device. The trace functionality is implemented as a simple TCP socket. A tool called TraceClient.exe, provided by dormakaba via the Access Manager web interface, is used to connect to the…

An RPC service, which is part of exos 9300, is reachable on port 4000, run by the process FSMobilePhoneInterface.exe. This service is used for interprocess communication between services and the Kaba exos 9300 GUI, containing status information about the Access Managers.…

Dormakaba provides the software FWServiceTool to update the firmware version of the Access Managers via the network. The firmware in some instances is provided in an encrypted ZIP file. Within this tool, the password used to decrypt the ZIP and extract the firmware is set…

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…

With physical access to the device and enough time an attacker can desolder the flash memory, modify it and then reinstall it because of missing encryption. Thus, essential files, such as "/etc/passwd", as well as stored certificates, cryptographic keys, stored PINs and so on…

With physical access to the device and enough time an attacker is able to solder test leads to the debug footprint (or use the 6-Pin tag-connect cable). Thus, the attacker gains access to the bootloader, where the kernel command line can be changed. An attacker is able to gain a…

The program libraries (DLL) and binaries used by exos 9300 contain multiple hard-coded secrets. One notable example is the function "EncryptAndDecrypt" in the library Kaba.EXOS.common.dll. This algorithm uses a simple XOR encryption technique combined with a cryptographic key…

The web interface offers a functionality to export the internal SQLite database. After executing the database export, an automatic download is started and the device reboots. After rebooting, the exported database is deleted and cannot be accessed anymore. However, it was…

The dormakaba Saflok system before the November 2023 software update allows an attacker to unlock arbitrary doors at a property via forged keycards, if the attacker has obtained one active or expired keycard for the specific property, aka the "Unsaflok" issue. This occurs, in…

The dormakaba registration units 9002 (PIN Pad Units) have an exposed UART header on the backside. The PIN pad is sending every button press to the UART interface. An attacker can use the interface to exfiltrate PINs. As the devices are explicitly built as Plug-and-Play to be…
