Vuln. Description:

OrbitHYIP contains a flaw that allows a remote cross site scripting attack.
This flaw exists because input passed to "referral" parameter in "signup.php"
and input passed to "id" parameter in "members.php" isn't properly sanitised
before being returned to the user.
This could allow a user to create a specially crafted URL that would execute
arbitrary code in a user's browser within the trust relationship between the
browser and the server, leading to a loss of integrity.

examples:

/signup.php?referral=[XSS]
/members.php?login=r0t&p=pwd&func=useinvestplan&id=[XSS]

###############################################
Solution:
Edit the source code to ensure that input is properly sanitised.
