Local privilege escalation via insufficient file verification
Published Dec 27, 2024 · Updated Dec 27, 2024
Improper privilege management in Huawei FusionCompute 6.3.0, 6.3.1, 6.5.0, 6.5.1, and 8.0.0 allows local users to elevate privileges. The deserialization path insufficiently verifies specific files before processing them; Huawei has not identified the files or deserializer. An attacker must already have low-privilege local system access, and successful exploitation grants higher privileges within the system.
