12. +file inclusion+
13. +found in /url.php?tmp_sid=
14. +so like site[dot]com/url.php?tmp_sid=[]
15. +attack description:
16. +The GET variable tmp_sid has been set to http://site[dot]com/some_inexistent_file_with_long_name.
17. +It is possible for a remote attacker to include a file from local or remote resources and
18. +or execute arbitrary script code with the privileges of the web server.

21. +cookie manipulation+
22. +found in register.php
23. +By injecting a custom HTTP header or by injecting a META tag,
24. +it is possible to alter the cookies stored in the browser.
25. +Attackers will normally manipulate cookie values to fraudulently authenticate themselves on a web site.
26. +By exploiting this vulnerability, an attacker may conduct a session fixation attack.
27. +In a session fixation attack, the attacker fixes the user's session ID before the user even logs into the target server,
28. +thereby eliminating the need to obtain the user's session ID afterwards.

33. +How to fix this vulnerability+
34. +
35. +You need to filter the output in order to prevent the injection of custom HTTP headers or META tags.
36. +Additionally, with each login the application should provide a new session ID to the user.
