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 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.
https://cwe.mitre.org/data/definitions/497.html →Open in CWE collection →An attacker sends a series of probes to a web application in order to elicit version-dependent and type-dependent behavior that assists in identifying the target. An attacker could learn information such as software versions, error pages, and response headers, variations in implementations of the HTTP protocol, directory structures, and other similar information about the targeted service. This information can then be used by an attacker to formulate a targeted attack plan. While web application fingerprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
