Hongjing HCM Local File Inclusion Scanner

The Hongjing HCM is an advanced management system used primarily in human resource departments across various organizations. It facilitates efficient management of employee records, payroll, and other HR processes. The software is favored for its robust features and flexibility, allowing companies to tailor its functionalities to meet unique operational needs. Its integration capabilities make it a popular choice for organizations requiring seamless transitions between HR and other administrative software. The software is reliable and often forms the backbone of HR operations, handling sensitive employee information. It is used by businesses to improve the efficiency of HR processes and ensure compliance with regulations.

Local File Inclusion (LFI) is a critical vulnerability that allows attackers to include files, which are stored locally on the server, through the web browser. LFI occurs when a web application provides a file path as an input and then uses this input in file operations without proper sanitization. It enables attackers to read sensitive files, sometimes leading to further security breaches like exposing configuration files. This vulnerability is particularly dangerous because it can potentially expose sensitive information and server configurations stored in local files. Attackers often exploit LFI vulnerabilities to gain unauthorized access to sensitive data or to execute malicious scripts. Proper input validation and file path restrictions are necessary to mitigate LFI risks.

The vulnerability in Hongjing HCM is in the /DownLoadCourseware interface, allowing arbitrary file reads by an unauthenticated user. Users can exploit this endpoint by manipulating file paths sent to the server, gaining access to sensitive system files like database and system configuration files. This improper handling of file inputs without sanitation facilitates unauthorized file access, posing significant security risks. The vulnerable parameter allows directory traversal techniques to retrieve files from unintended directories. The inclusion of local files by an attacker can lead to exposure of sensitive information critical to system security. To prevent this, strict validation and path sanitization procedures must be implemented at the application's file processing endpoints.

If exploited, this vulnerability can lead to severe security threats, exposing sensitive information such as system and database configuration data. Malicious actors could leverage this access to discover other weaknesses or gain further control over the system. The leak of sensitive files can result in unauthorized access to proprietary data and internal system operations, leading to operational disruptions. Data breaches might occur, causing reputational and financial damage to the affected organization. The information gathered via LFI could be used to stage more advanced attacks, including remote code executions or privilege escalations. Properly addressing this vulnerability reduces the risk of exposing sensitive information to unauthorized users.
