Unauthenticated remote code execution
Published Feb 25, 2021 · Updated Aug 3, 2024
Remote code execution in Microsoft Windows Fax Service allows remote attackers to run arbitrary code through network requests. Microsoft has not published the vulnerable function, input format, or incorrect operation performed on untrusted fax-service traffic. Exploitation requires no authentication or user interaction, but the Fax Service must be reachable; successful attacks execute code in the service context.
