Official description

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 socket and receive debug information. The data is permanently broadcasted on the TCP socket. The socket can be accessed without any authentication or encryption. The transmitted data is based on the set verbosity level. The verbosity level can be set using the http(s) endpoint with the service interface password or with the guessable identifier of the device via the SOAP interface. The transmitted data contains sensitive data like the Card ID as well as all button presses on Registration units. This allows an attacker with network level access to retrieve all entered PINs on a registration unit.

The underlying weakness: Exposure of Sensitive System Information to an Unauthorized Control Sphere

The product does not properly prevent sensitive system-level information from being accessed by unauthorized actors who do not have the same level of access to the underlying system as the product does.

How developers prevent this class of flaw

  • Production applications should never use methods that generate internal details such as stack traces and error messages unless that information is directly committed to a log that is not viewable by the end user. All error message text should be HTML entity encoded before being written to the log file to protect against potential cross-site scripting attacks against the viewer of the logs
