FeiFeiCms Local File Inclusion Scanner

FeiFeiCms is a content management system widely used by developers and organizations to create, manage, and maintain websites efficiently. It is particularly popular in sectors where quick deployment of content-driven sites is crucial. Web administrators and content creators use it to streamline their work, while developers appreciate its customizable and flexible nature. Due to its open-source format, it is accessible for personal and commercial use, making it a cost-effective solution for many users. However, due to security vulnerabilities, especially in configurations, it often requires monitoring and updating to ensure data safety and integrity.

Local File Inclusion (LFI) is a substantial vulnerability found within web applications, allowing an attacker to include files on a server through a web browser. This type of vulnerability often occurs when a file is accessed through an unvalidated input, leading to execution of unintended scripts or access to sensitive data. The LFI vulnerability can potentially escalate into further vulnerabilities like remote code execution. It introduces significant security risks as attackers may retrieve sensitive configuration or user data from the server. The simplicity of exploiting this vulnerability makes it particularly dangerous for administrators to overlook.

Technical details regarding the vulnerability include parameters in the FeiFeiCms URL structure that allow unauthorized file access. Specifically, the 'id' parameter can be manipulated to traverse directories and access configuration files such as 'config.php'. This could expose database credentials stored within these files, allowing malicious users to compromise the database. The template employs matchers to confirm successful exploitation by identifying PHP and database-specific keywords in HTTP responses. These clues help ascertain whether the vulnerability allows unintended file inclusions, posing a threat to the server’s file system integrity.

When exploited by malicious actors, this vulnerability can lead to unauthorized access to sensitive configuration and user data. Attackers may leverage the included files to gather credentials and gain unauthorized control over the application or server. This can result in significant data breaches, data corruption, and interruptions to the service. Additionally, successful exploitation can diminish user trust and have serious implications for privacy and data integrity. Maintaining server and client security requires proactively mitigating these risks.
