Отправить #622222: D-Link DIR-513 1.10 Buffer Overflow

The DIR-513 device's web service, implemented via the boa program, initializes through the websAspInitfunction which registers callback APIs. A POST request to /goform/formSetWanL2TPtriggers the formSetWanL2TPcallback function. This function retrieves the curTimeparameter from the request body and passes it unsanitized to sprintf(v11, "%s?t=%s", last_url, Var), where it gets concatenated into a stack buffer. Due to missing length validation, an oversized curTimevalue triggers a stack overflow that may crash the service (DoS) or, with further exploitation, grant shell access.
