Overview
The PHP Local File Inclusion vulnerability, designated as CVE-2025-30992, is a critical security flaw found in the Thembay Puca software. This vulnerability is of particular concern due to its potential to facilitate unauthorized access to sensitive data or even a complete system compromise. As the bug originates from an improper control of filename for include/require statement in a PHP program, it presents a significant risk to any system running affected versions of Thembay Puca.

How the Exploit Works
The PHP Remote File Inclusion vulnerability is a type of vulnerability that allows an attacker to inject a remote file into the server via a PHP script. This is possible due to weak validation of the ‘include’ and ‘require’ statements in the script. When improperly handled, these statements can be manipulated to include files from remote servers, which may contain malicious code.
In the case of CVE-2025-30992, the vulnerability lies within Thembay Puca’s improper control of filename for include/require statement, which could be exploited to include arbitrary local files from the server. This could potentially lead to a full system compromise or data leakage.
Conceptual Example Code
Below is a conceptual example demonstrating how an attacker might exploit this vulnerability. This example supposes a malicious actor issuing an HTTP request to a vulnerable endpoint, using a manipulated file path to include a local file:
GET /vulnerable/endpoint?file=../../../../etc/passwd HTTP/1.1
Host: target.example.comIn this example, the attacker attempts to include the ‘/etc/passwd’ file, a crucial system file that contains user account details. If successful, the attacker would have unauthorized access to sensitive data.
Please note that this is a simplified example for illustrative purposes only. Real-world exploits may involve more complex methods and additional steps to bypass security measures.
