Huijietong Local File Inclusion Scanner

Huijietong is a software application commonly used in environments where integrated information management is key, such as educational institutions or large enterprises. It is designed to facilitate the management of resources, operations, and data, thereby promoting efficiency and consistency. The software is popular among organizations seeking a centralized approach to data handling and application management. Users of Huijietong typically include data administrators and IT personnel responsible for maintaining the integrity and accessibility of information within an organization. The platform offers various modules and tools that enable users to execute and monitor multiple administrative tasks. This active engagement with critical data and system functions makes understanding vulnerabilities within such software especially important.

Local File Inclusion (LFI) vulnerabilities typically occur when a web application includes files on a server without adequate validation. This vulnerability can allow an attacker to manipulate file paths to access restricted files stored on the same server or to execute unauthorized scripts. In the case of Huijietong, this vulnerability may allow unauthorized access to sensitive configuration files or even execution of scripts, if the server is improperly configured. Attackers exploiting LFI vulnerabilities can potentially gain significant insights into the server's file system, which can be leveraged for further attacks. Such vulnerabilities are particularly concerning because they may not require authentication, allowing them to be exploited by remote attackers.

The technical mechanism driving an LFI involves manipulating file path parameters used by a web application. In Huijietong, specific API endpoints allow for file download functionality, which if not properly validated, becomes a vector for LFI attacks. An attacker can exploit this by submitting crafted POST requests that point to sensitive files on the server. The vulnerable endpoint identified in this context is "{{BaseURL}}/fileDownload?action=downloadBackupFile", which accepts file path parameters that can be manipulated. Effective exploitation relies on the application's error responses or the presence of predictable file paths, which attackers use to confirm successful access to restricted data.

Exploitation of LFI vulnerabilities in Huijietong can result in various potential impacts. One significant risk is unauthorized access to critical system files, such as '/etc/passwd' on Linux servers, which may contain sensitive user data. Additionally, this vulnerability can lead to further system compromise, such as privilege escalation or creation of backdoors, if exploited by skilled attackers. In some cases, attackers may be able to read local application code, which can reveal another layer of security weaknesses or sensitive business logic. From a business perspective, such an exposure undermines customer trust and can result in significant data privacy concerns and compliance failures.
