Overview
The CVE-2025-28944 vulnerability is a significant security issue impacting the PHP-based snstheme Avaz. This vulnerability, known as PHP Remote File Inclusion, allows an attacker to include local files from the server through improper control of filename for include/require statement in the PHP program. This vulnerability affects many businesses and individuals who utilize snstheme Avaz, potentially leading to system compromise or data leakage. With a CVSS Severity Score of 8.1, it’s a high-risk vulnerability that requires immediate attention to prevent potential exploitation.

How the Exploit Works
PHP Remote File Inclusion (RFI) vulnerabilities occur when a PHP application doesn’t properly validate user input for file inclusion requests. In the case of CVE-2025-28944, the affected snstheme Avaz doesn’t adequately control filenames for include/require statements, allowing an attacker to manipulate the input and include arbitrary local files from the server. This can lead to the execution of malicious server-side scripts and potentially lead to a system compromise or significant data leakage.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. In this example, an attacker sends a malicious HTTP POST request to a vulnerable endpoint:
POST /vulnerable_endpoint.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
include_file=../../etc/passwdIn this request, the attacker is attempting to include the “/etc/passwd” file, a common target in Unix-like systems as it contains user account information. If the vulnerable PHP script doesn’t correctly validate the “include_file” parameter, the server will respond with the contents of the “/etc/passwd” file, giving the attacker potentially valuable information to further exploit the system.
Mitigation and Prevention
The most effective way to mitigate this vulnerability is to apply patches provided by the vendor. If a patch is not available, a workaround would be to use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to monitor the network for any suspicious activities. Also, ensure that all user inputs are correctly validated and sanitized before using them in file include or require statements to prevent potential PHP RFI vulnerabilities.
