Windows Routing and Remote Access Service (RRAS) Remote Code Execution Vulnerability
Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to execute code over a network.
FAQ
How could an attacker exploit this vulnerability? An attacker could exploit this vulnerability by tricking a user into sending a request to a malicious server via the Routing and Remote Access Service (RRAS) Snap-in. This could result in the server returning malicious data that might cause arbitrary code execution on the user's system.
