Authenticated code execution via RRAS integer overflow
Published Mar 10, 2026 · Updated Mar 10, 2026
Integer overflow in Microsoft Windows RRAS allows remote authenticated users to execute code through a network connection. Microsoft identifies an integer wraparound and heap overflow, but does not disclose the affected parser, field, or allocation operation. Exploitation requires existing low privileges and user interaction; success runs attacker-controlled code on the affected system.
