CVE-2025-62549 is a remote code execution vulnerability in Windows Routing and Remote Access Service (RRAS) caused by an untrusted pointer dereference. The flaw can be triggered over the network when RRAS processes attacker-controlled data from a malicious server after a connection is initiated. Available reporting indicates exploitation involves deceiving a user into initiating a connection or sending a request to an attacker-controlled server, which then returns crafted data that leads RRAS to dereference an untrusted pointer. Successful exploitation allows code execution in the context of the vulnerable service.
