CVE-2023-50916 Information

Description

Kyocera Device Manager before 3.1.1213.0 allows NTLM credential exposure during UNC path authentication via a crafted change from a local path to a UNC path. It allows administrators to configure the backup location of the database used by the application. Attempting to change this location to a UNC path via the GUI is rejected due to the use of a \ (backslash) character which is supposed to be disallowed in a pathname. Intercepting and modifying this request via a proxy or sending the request directly to the application endpoint allows UNC paths to be set for the backup location. Once such a location is set Kyocera Device Manager attempts to confirm access and will try to authenticate to the UNC path; depending on the configuration of the environment this may authenticate to the UNC with Windows NTLM hashes. This could allow NTLM credential relaying or cracking attacks.
