Server-side Request Forgery (SSRF)

Overview starlette is a The little ASGI library that shines. Affected versions of this package are vulnerable to Server-side Request Forgery SSRF in the StaticFiles file on Windows systems when handling UNC paths. An attacker can obtain NTLMv2 credentials of the service account by sending a...

Starlette: SSRF and NTLM credential theft via UNC paths in StaticFiles on Windows

Summary When serving static files on Windows, StaticFiles resolves the requested path with os.path.realpath. If a UNC path such as \attacker.com\share reaches the resolver, realpath causes the process to open a connection to the remote host over SMB port 445. This is a server-side request forgery...
