The remote host is vulnerable to a buffer overflow.
The remote host seems to be running Sami HTTP Server v1.0.4 or older. A vulnerability has been reported for Sami HTTP server v1.0.4. An attacker may be capable of corrupting data such as return address, and thereby control the execution flow of the program. This may result in denial of service or execution of arbitrary code.
Use another web server since Sami HTTP is not maintained any more.
