Description:
Luigi Auriemma has reported a vulnerability in Netwin SmsGate, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error when handling HTTP "Content-Length" headers. This can be exploited to cause the service to stop responding when it displays a debug message box via e.g. a specially crafted HTTP request containing an overly large "Content-Length" header value.
NOTE: Reportedly, the DoS lasts only as long as the debug message box is displayed and the server resumes if e.g. an admin selects the "Ignore" button.
Solution:
Restrict network access to the service.
