Description:
badpack3t has discovered two vulnerabilities in FreeProxy, which can be exploited by malicious people to gain knowledge of sensitive information or cause a DoS (Denial of Service).
The vulnerabilities are both present in the built-in web server (FreeWeb) and are caused due to errors in the handling of HTTP requests.
An input validation error can be exploited to conduct classic directory traversal attacks and thereby escape the web root.
Example:
http://[victim]/../../../../boot.ini%00.html
A NULL pointer dereference bug can be exploited to crash the process by sending a malformed HTTP GET request without the "/" character when requesting a resource.
Example:
GET AAA HTTP/1.0
The vulnerabilities affect versions prior to 3.61 "build: Jan 9 2004 at 21:39:21".
Solution:
Update to version 3.61 "build: Jan 9 2004 at 21:39:21".
