Device-service interruption via unchecked packet copy
Published Feb 27, 2023 · Updated Mar 11, 2025
Buffer overflow in Huawei BiSheng-WNM FW 3.0.0.325 allows remote attackers to interrupt device services via malicious network packets. An undisclosed firmware component copies attacker-controlled packet data into a fixed-size buffer without checking the input length. No authentication or user interaction is required, and the reported consequence is limited to device service exceptions.
