Title: Huawei HiSuite Insecure Service Directory ACLs
________________________________________________________________________

A privilege escalation vulnerability was identified in the Huawei
HiSuite software which can be used by a local user to elevate
privileges to become the SYSTEM user.

The root cause of the problem are insecure ACLs on the HandSet service
directory which allows any authenticated user to place a crafted DLL
file in that directory to perform a DLL hijacking attack.

Huawei has released software updates to address the issue. The full
advisory with technical details is available at the following link:
