Remote code execution via RRAS 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 user interaction. Microsoft identifies the flaw as a heap-based overflow in RRAS but has not disclosed the affected parser, input, or incorrect bounds operation. Exploitation requires a user to take an unspecified action, after which code runs in the RRAS service context.
