Remote code execution via undisclosed heap overflow
Published Aug 13, 2024 · Updated Jul 10, 2025
Heap-based buffer overflow in Microsoft Windows Server RRAS allows remote attackers to execute code after required user interaction. Microsoft identifies the affected locus only as RRAS and has not disclosed which input overruns which heap buffer. Exploitation requires an unauthenticated attacker and user interaction, after which code can run in the RRAS process context.
