[*] Discovered By: t0pP8uZz  
[*] Contact: irc.rizon.net #sectalk  
[*] Discovered On: 22 October 2008  
[*] Script Download: http://www.mywebcards.net/  
[*] DORK: "Powered By Webcards"  
  
  
  
[*] Vendor Has Not Been Notified!  
  
  
  
[*] DESCRIPTION/USAGE:   
  
WebCards 1.3 and prior versions suffer from a MySQL injection in the admin login  
page, This allows remote attackers to gain access to the administration area  
without having a valid user/pass combination.  
  
All what is needed is the valid username, The default admin username is "admin" so  
the below SQL syntax should gain entry to a vulnerable site.  
  
Not all sites are vulnerable, It relys on Magic Quotes, and other script settings for  
this to work, I tested on about 15 sites, and 2 of those 15 were only vulnerable.  
  
Once in the administration area its possible to get a very easy shell, Which is  
explained in the "Notes" section of this document.  
  
  
  
[*] SQL Injection:  
  
First find a vulnerable site, Then goto http://site.com/webcards/admin.php  
  
Enter the following in the username textbox: admin" and ""="  
Enter the following in the password textbox: 1  
  
  
  
[*] NOTE/TIP:   
  
To gain a shell on the vulnerable host, Simply use the sql injection above, Once  
administration is gained, Click "Add Image Macro" follow the onscreen instructions  
and change the extension to php or what ever file type you want.  
  
Once complete goto "Images" and upload your shell/file, When its complete, Navigate  
back to images, Goto "Show All" and look for your file name, then just copy the LINK.
