Hrsale Local File Inclusion Scanner

Hrsale is a human resource management software widely used by businesses to efficiently manage employee information and HR-related tasks. It is predominantly deployed in small to medium-sized organizations for streamlining HR operations and maintaining employee records. The software provides functionalities such as attendance management, payroll processing, and performance tracking. Organizations adopt Hrsale to facilitate HR processes, improve productivity, and ensure compliance with regulatory requirements. As it handles sensitive information, security is of utmost importance for its users. By employing Hrsale, HR departments can focus more on strategic initiatives while reducing manual work and errors.

The Local File Inclusion (LFI) vulnerability allows an attacker to trick the web application into exposing or running files on the web server. This flaw arises when the application includes files based on user inputs without properly validating them. As a result, attackers can exploit this vulnerability to access sensitive files, including configuration files or system files of the server. In Hrsale 2.0.0, this can be achieved by manipulating the file path parameters used in the application. Identifying and patching this vulnerability is crucial to prevent unauthorized file access or information leakage.

In the given nuclei template, the LFI vulnerability is exploited by sending a HTTP GET request to a specific endpoint of Hrsale using a crafted path. The vulnerable endpoint is "/download?type=files&filename=" which does not validate the file name parameter adequately. By adding a specific pattern like "../../../../../../../etc/passwd", an attacker can access the sensitive system file '/etc/passwd' of the server. This vulnerability is dangerous because it can disclose information about system users and potentially aid in further exploitation. Proper input validation and restricting file access are critical steps in mitigating such risks.

The exploitation of a Local File Inclusion vulnerability in Hrsale could lead to serious security impacts. Attackers could gain unauthorized access to sensitive files and system information stored on the server. This might facilitate further attacks, such as privilege escalation or the compromise of user accounts. The exposed data could be misused for identity theft or to launch more targeted attacks. Furthermore, unauthorized access to configuration files could permit attackers to discover database credentials or other sensitive information. Prompt addressing and fixing of this vulnerability are essential to prevent potential data breaches and ensure security compliance.
