CVE-2021-22311Network attack vector

Authenticated privilege escalation via improperly hardened process

Published Mar 22, 2021 · Updated Aug 3, 2024

Improper permission assignment in Huawei ManageOne 8.0.0 and 8.0.1 allows remote authenticated users to perform high-privilege operations. Huawei identifies an improperly hardened process that runs with elevated privileges but does not disclose the process, permission boundary, or affected operation. Exploitation requires high-privilege network access to the target and combination with another vulnerability; resulting confidentiality, integrity, and availability effects are limited.
