AV Arcade BugFix – XSS Exploit

AV Arcade BugFix – XSS Exploit

Jan 06

The Problem:

EDITED::…
This was originally reported as link spam, but could easily be a lot worse.

When registering, the user name field is open to possible attack.
Code will be processed on the members page.
The code can be overflown to the homepage fairly easily.
XSS can be used.

I would now consider this as a serious exploit.
I would suggest fixing this bug A.S.A.P

The Fix:

• Backup then open yoursite.com/register.php
• Find:
  $info2 = htmlspecialchars($info);
• Add below:
  $username = htmlspecialchars($username);
• Backup then open yoursite.com/admin/manage_users.php
• Find:
• while($row = mysql_fetch_array($sql)){
• Add below:
• $username = htmlspecialchars($username);
• Save and upload all files.
• Search your members list for any user names shown as code and delete (You could also I.P. ban them).

This function could easily be expanded for further validation.
