Description:
Recently, a directory traversal vulnerability was discovered in iWeb Mini Web Server. The vendor fixed this by issuing a new version, but the vulnerability was not fixed properly.
A malicious person may still conduct a directory traversal attack by supplying the URL encoded values for "..\" in a HTTP request to the web server.
Example:
http://[victim]/%2e%2e%5c%2e%2e%5c%2e%2e%5c%2e%2e%5cwindows\system.ini
The vulnerability has been confirmed in version 2.0.1.4.
Previous advisory:
