Unauthenticated remote code execution
Published Sep 9, 2025 · Updated Sep 9, 2025
Integer overflow in Microsoft Windows Server RRAS allows remote attackers to execute code over a network after user interaction. Microsoft identifies RRAS and the overflow class but has not disclosed the affected function, input field, or arithmetic operation. Exploitation requires no prior privileges but does require user interaction; successful exploitation executes attacker-controlled code in the RRAS context.
