CVE-2024-27910Network attack vector

Unauthenticated printer reboot via undisclosed request

Published Apr 5, 2024 · Updated Aug 20, 2024

Authorization bypass in Lenovo printer firmware allows remote attackers to reboot affected printers over the network without authentication. Lenovo has not disclosed the request, endpoint, protocol, or missing authorization check that triggers the reboot. Network reachability to an affected printer is sufficient; the documented consequence is a reboot that interrupts printing, with no reported data access or modification.
