CVE-2024-2961 Scanner

PHP is a popular general-purpose scripting language especially suited to web development. PHP is fast, flexible and pragmatic, and powers everything from your blog to the most popular websites in the world. It is widely used by developers and companies for developing server-side web applications. The vulnerability checked by the scanner is found in PHP which is used in a plethora of web applications globally. This vulnerability can allow unauthorized actions if not properly checked. This emphasizes the need for careful management of user input and its processing in PHP.

Local File Inclusion (LFI) is a vulnerability that allows an attacker to include files on a server through the web browser. This vulnerability can lead to code execution on the server, depending on what files can be included. LFI can be used to include files such as /etc/passwd, which could give an attacker additional information about the server or its configuration. By exploiting the LFI vulnerability, attackers could escalate their privileges on the server. This vulnerability often arises due to insufficient input validation or sanitization mechanisms in the application.

The PHP LFI vulnerability exists when user input is not properly validated before being used in a file inclusion command. Attackers can exploit this vulnerability by supplying paths to sensitive files on the server, including PHP's own system files. This template checks for the presence of PHP's LFI via the payload specified, testing if system-critical files can be accessed. If successful, the vulnerability can grant attackers unauthorized access. The template's method employs HTTP communication to send crafted requests to a web server to determine the presence of the LFI vulnerability.

If exploited, the LFI vulnerability could result in significant consequences such as unauthorized access to sensitive information and potential remote code execution. This can allow attackers to alter server configurations, disclosure of user credentials, or even disrupt server functionality. It opens a dangerous attack vector whereby malicious software could be served as a response to requests. Attackers may leverage this vulnerability to launch further attacks against user accounts or the server itself. Ultimately, exploiting this vulnerability could lead to a complete compromise of the server.
