Windows has a flaw in how it handles ALPC (Advanced Local Procedure Call) that allows a user with limited permissions to gain higher-level access on the system. This is dangerous because it lets attackers escalate their privileges and take control of the computer.
Technical detail
An elevation of privilege vulnerability in Windows ALPC handling allows a local, authenticated attacker to escalate privileges to system or administrator level through improper validation of ALPC calls. Requires local access and user-level credentials; successful exploitation grants unrestricted system access.
