Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server contains a PHP application that is affected by
multiple flaws.

Description :

The remote host is running SilverNews, a free news script written in
PHP.

The version of SilverNews installed on the remote host suffers from
several flaws :

- SQL Injection Vulnerability
The application does not sanitize user-supplied input to the
'username' parameter of the 'admin.php' script before using
it in database queries. By exploiting this flaw, a possible hacker
can bypass authentication and possibly disclose or modify
data or launch attacks against the underlying database.

- Arbitrary PHP Code Execution Vulnerability
The application permits administrators to edit template
files, which may contain HTML as well as PHP code to be
used, for example, as footers with dynamically generated
pages. In conjunction with the SQL injection flaw noted
above, a possible hacker can exploit this issue to execute
arbitrary PHP code on the remote host within the
context of the web server userid.
