Authenticated remote 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 interaction. Microsoft has not disclosed the affected RRAS routine, the attacker-controlled field, or the arithmetic operation that produces the overflow. Exploitation requires low privileges and user interaction; successful code execution can compromise the affected Windows Server host.
