CVE-2022-45460Public exploitNetwork attack vector

Unauthenticated code execution via unbounded URI formatting

Published Mar 28, 2023 · Updated Feb 19, 2025

Stack-based buffer overflow in Xiongmai MBD6304T and NBD6808T-PL firmware allows remote attackers to execute arbitrary code via HTTP. The Sofia web server passes an overlong request URI to sprintf without bounding the write, overflowing a stack buffer and allowing control of program flow. No authentication or user interaction is required on MBD6304T 4.02.R11.00000117.10001.131900.00000 or NBD6808T-PL 4.02.R11.C7431119.12001.130000.00000; exploitation executes code as root or crashes the web server and reboots the recorder.
