CVE-2018-7935Public exploitNetwork attack vector

Unauthenticated temporary network service interruption

Published Feb 10, 2023 · Updated Mar 24, 2025

Denial of service in Huawei E5573Cs-322 firmware 21.328.01.00.00 allows remote attackers to interrupt network access. Huawei has not published the affected request handler or the input-processing operation that fails on attacker-controlled traffic. No authentication or user interaction is required, and successful exploitation makes the device's network temporarily unavailable rather than permanently disabling it.
