Local privilege escalation via improper memory handling
Published Mar 12, 2020 · Updated Aug 4, 2024
Memory corruption in the Microsoft Windows ActiveX Installer Service allows local users to elevate privileges via a crafted application. Microsoft identifies improper memory handling in the service but has not published the affected routine, object, or invalid memory operation. Exploitation requires prior code execution on the target and can grant privileges beyond those of the calling user.
