CVE-2021-22397

Local privilege escalation via unchecked file parameters

Published Aug 2, 2021 · Updated Aug 3, 2024

Privilege escalation in Huawei ManageOne 8.0.0 allows local users with high privileges to gain higher privileges through local files. Unspecified local files accept external parameters without validation when invoked; Huawei has not disclosed their names or parameter handling. Exploitation requires the ability to execute those files locally with high privileges and grants access reserved for a higher-privileged account while disrupting normal service.
