Unauthenticated code execution via RRAS heap overflow
Published Sep 9, 2025 · Updated Sep 9, 2025
Heap-based buffer overflow in Microsoft Windows Server RRAS allows remote attackers to execute code over a network with user interaction. Microsoft identifies the affected component and heap corruption class but does not disclose the parsing locus or which untrusted network input overruns the heap buffer. The attack requires no prior authentication and user interaction, after which attacker-controlled code executes on the affected server.
