  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.
  19.  +-----------------+-----------------+-----------------+
  20.  +[2]
  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.

  30.  +vuln:
  31.  +Email=<meta+http-equiv='Set-cookie'+content='cookiename=cookievalue'>&[email protected]&register=Register
  32.  +-----------------+-----------------+-----------------+
  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.
