CVE-2023-50916

https://notcve.org/view.php?id=CVE-2023-50916

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. • https://www.kyoceradocumentsolutions.us/en/about-us/pr-and-award-certifications/press/kyocera-device-manager-cve-2023-50196-vulnerability-solution-update.html https://www.trustwave.com/en-us/resources/security-resources/security-advisories https://www.trustwave.com/hubfs/Web/Library/Advisories_txt/TWSL2024-001_kyocera-v2.txt • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
