Two vulnerabilities have been identified in Snowblind Web Server. One allows malicious people to conduct directory traversal and the other is a Denial of Service vulnerability.

The directory traversal vulnerability is caused due to missing filtering of "../" sequences. This allows malicious people to request files outside the web root. This may be done directly or by using the "internal.sws" script.

The Denial of Service vulnerability can be exploited to crash the web server in two ways, either by requesting "/</" or by requesting a string that is longer than 219 characters.

Solution
If you choose to use Snowblind Web Server on the Internet or other untrusted networks, you should implement a reverse proxy that can filter potentially malicious requests.
