CVE-2024-3286Network attack vector

Unauthenticated restart via crafted web request

Published May 16, 2024 · Updated Sep 6, 2024

Stack-based buffer overflow in some Lenovo printers allows remote attackers to restart the device through a crafted web request. Lenovo identifies the affected locus only as web-request handling and has not disclosed which request field overflows the stack buffer or which routine copies it without an adequate bounds check. No authentication or user interaction is required, and successful exploitation interrupts printing by rebooting the device without reported data disclosure or modification.
