Vulnerabilidades

A denial-of-service vulnerability was found in the firmware used in Lenovo printers, where users send illegal or malformed strings to an open port, triggering a denial of service that causes a display error and prevents the printer from functioning properly.

Standard users can directly operate and set printer configuration information , such as IP, in some Lenovo Printers without having to authenticate with the administrator password.

A remote code execution vulnerability was found in the firmware used in some Lenovo printers, which can be caused by a remote user pushing an illegal string to the server-side interface via a script, resulting in a stack overflow.
