Bug vulnerability class | Cross Site Scripting |
Bug description | The remote host is running a vulnerable version of w-Agora, a web-based forum management software written in PHP. There is a cross site scripting vulnerability affecting the file index.php during username input validation. There is also an SQL injection vulnerability in the file redir_url.php which may allow an attacker to execute arbitrary SQL statements in the remote database. And an HTTP response splitting vulnerability which may also allow an attacker to perform cross-site scripting attacks against the remote host. |
Bug solution | Upgrade the software to the latest version. The server and CGI suite should be deactivated or de-installed if not necessary. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8081). Try to prevent unwanted connection attempts by filtering traffic with firewalling. Alternation of the application banner can confuse an attacker and let him determine the wrong software. |
