The Ruoyi Management System is a widely used software for managing business operations and streamlining workflow processes. This system is typically employed by organizations looking for an efficient way to manage tasks, users, and data. It offers a user-friendly interface for non-technical users while providing extensive features that meet the needs of more tech-savvy administrators. Businesses spanning various sectors, from small to medium-sized enterprises, utilize this system to optimize their management tasks. Its integration capabilities make it a suitable choice for deployment in diverse IT environments. The role it plays in enhancing efficiency and data management makes it a popular tool among firms looking to modernize their operations.

Local File Inclusion (LFI) vulnerabilities are critical security flaws found in web applications that allow attackers to include files located on the server. The vulnerability leverage this by inserting special characters to access restricted system files. An LFI vulnerability can lead to unauthorized file access and disclosure of sensitive information stored on the server. Attackers can potentially exploit this weakness to traverse directory paths and read files like '/etc/passwd' on Unix systems, which can contain critical information. This vulnerability type often represents a significant security risk, as it can provide attackers with the reconnaissance needed to carry out more serious attacks. It underscores the importance of strict file path validation and code sanitization within applications.

The technical details of the Local File Inclusion vulnerability in the Ruoyi Management System involve manipulation of URL parameters. Specifically, the vulnerability is exploited by appending directory traversal sequences such as '../../..' within the 'resource' parameter. This suggests a lack of proper input validation or sanitization, allowing unauthorized inclusion of server-side files. The exploits involve HTTP GET requests where the affected endpoint '/common/download/resource' is targeted. By targeting this endpoint, attackers aim to retrieve system files such as '/etc/passwd' or 'win.ini' based on the operating system in use. Detecting such vulnerabilities usually encompasses regex or word matches indicative of file inclusion, giving attackers insight into server file structures.

Exploiting the Local File Inclusion vulnerability can have severe effects. It enables attackers to access sensitive configuration files, compromising system security and privacy. Unauthorized access to server files could lay the groundwork for further exploitations, such as privilege escalation or code execution. Confidential information exposed this way could result in data breaches, legal implications, and loss of customer trust. Compromised systems might also serve as entry points for more intrusive attacks like malware distribution, amplifying the risk spectrum. Therefore, it's crucial for organizations to regularly assess and patch such vulnerabilities to protect their infrastructure.
