CVE-2022-34159Network attack vector

Service interruption via unvalidated network packets

Published Dec 20, 2024 · Updated Dec 24, 2024

Improper input validation in Huawei CV81-WDM Firmware 01.70.49.29.46 allows remote attackers to interrupt device services via network packets. The firmware fails to strictly verify packets received through device network ports before processing them. Any remote attacker able to reach those ports can send a crafted packet that interrupts printer services, with no reported data exposure or modification.
