How the Exploit Works
The exploit takes advantage of the improper control in the PHP program where the filename for include/require statement is not properly handled. An attacker can remotely manipulate the affected file’s path, thereby allowing the inclusion of local files outside the intended directories. This can lead to unauthorized execution of arbitrary PHP code in the context of the webserver, potentially compromising the system or leading to data leakage.
Conceptual Example Code
The vulnerability might be exploited as per the following conceptual example:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"file_path": "../../../../malicious.php"
}In the example above, an attacker sends a POST request with a malicious file path, tricking the server into executing code from unintended directories.
Mitigation Guidance
To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it is available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure, helping to detect and block malicious requests.
