Vulnerabilidades

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…

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 (cryptoKey) to transform each character of…

A local privilege escalation vulnerability has been identified in the Kaba exos 9300 System management application (d9sysdef.exe). Within this application it is possible to specify an arbitrary executable as well as the weekday and start time, when the specified executable should be run with SYSTEM privileges.

Exos 9300 instances are using a randomly generated database password to connect to the configured MSSQL server. The password is derived from static random values, which are concatenated to the hostname and a random string that can be read by every user from the registry. This allows an attacker to derive the database…

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. Interacting with the service does not require…

Multiple hardcoded credentials have been identified, which are allowed to sign-in to the exos 9300 datapoint server running on port 1004 and 1005. This server is used for relaying status information from and to the Access Managers. This information, among other things, is used to graphically visualize open doors and…

On the exos 9300 server, a SOAP API is reachable on port 8002. This API does not require any authentication prior to sending requests. Therefore, network access to the exos server allows e.g. the creation of arbitrary access log events as well as querying the 2FA PINs associated with the enrolled chip cards.
