Service interruption via insufficiently validated file upload

Published May 27, 2021 · Updated Aug 3, 2024

Insufficient input validation in FusionCompute 8.0.0 allows remote authenticated users to upload arbitrary files to the device. Huawei has not disclosed the affected component or the validation operation that accepts attacker-controlled file content or paths. Exploitation requires access to the affected device and can interrupt the service, but the vendor does not identify whether the result is a hang, crash, or other abnormal state.
