Vulnerability description

Trustwave CVE-2023-50916

The reported vulnerability concerning Kyocera Device Manager has a Path Traversal for UNC (any shared network path) vulnerability. Path Traversal is an attack on web applications. When intercepting access, the attacker can change the local path to a UNC path. Upon receiving the UNC path, Kyocera Device Manager will attempt to confirm the access and then will try to authenticate the UNC path. The attacker can possibly exploit UNC path authentication.

Risk summary

There is a risk of authentication information leakage if the attacker successfully obtains the authentication information, they can gain unauthorized access to clients’ accounts, steal data, or carry out malicious activities on Kyocera product devices.

NOTE: The attacker must be on the same network as the Kyocera Device Manager to exploit this vulnerability.

Countermeasure

There is no workaround; the issue will be addressed by an update.

Kyocera is scheduled to release a security update on December 22nd, 2023. The update will implement a validation function, that if a path is changed to an invalid path, the invalid path is ignored and the original valid path is still applied.

Please contact your dealer, authorized reseller, or servicing agent to confirm if your device is affected and for information on how to apply any necessary updates.

This security vulnerability requires an attacker to be logged in and have direct access to your network in order to take advantage and pose a real risk. Contact the Hotline for information on how to secure the devices on your network and apply firmware updates.
