How the Exploit Works
The vulnerability is due to improper handling of filenames for include/require statements in the PHP program. An attacker can manipulate these statements to include local files from the server. This can allow the attacker to execute arbitrary PHP code on the affected system, leading to potential system compromise or data leakage.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited:
GET /vulnerable/endpoint?file=../../../etc/passwd HTTP/1.1
Host: target.example.comIn this example, the attacker sends a GET request to a vulnerable endpoint of the target server, attempting to include the ‘/etc/passwd’ file, which contains user password data.
Mitigation Guidance
Users are strongly advised to apply the vendor-supplied patch immediately. In situations where immediate patching is not feasible, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. However, these measures do not fully resolve the vulnerability, but can help protect against exploitation.
