Detailsinfo

A vulnerability was found in Dormakaba Kaba exos 9300 (version now known). It has been classified as very critical. Affected is some unknown processing. The manipulation with an unknown input leads to a hard-coded credentials vulnerability. CWE is classifying the issue as CWE-798. The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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 alerts. However, controlling the Access Managers via this interface is also possible. To send and receive status information, authentication is necessary. The Kaba exos 9300 application contains hard-coded credentials for four different users, which are allowed to login to the datapoint server and receive as well as send information, including commands to open arbitrary doors.
