Ruijie Networks Switch eWeb Local File Inclusion Scanner

Ruijie Networks Switch eWeb is a management interface used for network switch configurations, primarily utilized by network administrators. It supports a range of features for efficient network management and is widely deployed in various organizational infrastructures. The product is prominent in enterprises looking for scalable and robust network solutions. Ruijie Networks Switches are known for their reliability and feature-rich interfaces designed to ease network operations. Typically, these switches are installed in large corporations, data centers, and educational institutions for comprehensive network management. The eWeb system facilitates remote switch management, significantly aiding in seamless network operations.

Local File Inclusion (LFI) is a vulnerability that allows attackers to access unauthorized local files on the server by exploiting inadequately sanitizing input parameters. This security flaw could expose sensitive data stored on the server, leading to information disclosure. The vulnerability is often exploited through improperly configured file paths within web applications. LFI attacks can escalate to more severe intrusions if leveraged alongside other vulnerabilities or exploits. As such, monitoring and controlling file access permissions is critical in mitigating such vulnerabilities. Regular audits and secure coding practices are essential to safeguard against LFI attacks.

The detected LFI vulnerability in Ruijie Networks Switch eWeb involves unauthorized access through the 'download.do' endpoint. Attackers can craft malicious URLs that exploit the endpoint to include and expose local files like 'config.text'. The vulnerability leverages path traversal techniques, opening avenues for information disclosure if exploited successfully. The problem arises from inadequate validation and sanitization of file request parameters. By manipulating relative paths, remote attackers can access restricted directory contents. Consequently, the vulnerability has a direct impact on confidentiality, with potential exposure of configuration details.

If successfully exploited, the LFI vulnerability can lead to unauthorized disclosure of sensitive configuration files, thus compromising network security. Malicious actors could retrieve contents of configuration files stored on the server, potentially gaining insights into network setup or credentials. This information could be used to facilitate further attacks, such as gaining unauthenticated entry into network infrastructure. The security compromise may lead to severe service disruption or unauthorized administrative control. Further compounded vulnerabilities in the affected systems might result in more damaging exploits, like Remote Code Execution (RCE).
