Privilege escalation via PMS permission-management flaw

Published Dec 6, 2023 · Updated Aug 2, 2024

Permission management in Huawei HarmonyOS and EMUI allows remote attackers to escalate privileges through the PMS module. Huawei identifies HarmonyOS 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0 as affected but has not disclosed the PMS locus or incorrect permission operation. Remote unauthenticated reachability is reported, while the attained privilege level and resulting capabilities remain undisclosed.
