CVE-2022-48255Network attack vector

Unauthenticated code execution via unfiltered command input

Published Feb 27, 2023 · Updated Mar 11, 2025

Command injection in Huawei BiSheng-WNM firmware 3.0.0.325 allows remote attackers to execute code through crafted network input. The printer firmware fails to filter special characters in external input before incorporating that input into a system command. Network access to the printer is sufficient; successful exploitation executes attacker-supplied code without authentication.
