source: https://www.securityfocus.com/bid/12722/info
CProxy is reported prone to a remote directory traversal vulnerability. This issue arises due to insufficient sanitization of user-supplied data. A remote user may exploit this issue to disclose arbitrary files and carry out a denial of service condition.
It is reported that an attacker can simply issue an HTTP GET request including directory traversal sequences to carry out this attack.
GET http://../../[file] HTTP/1.0
