Sangfor Application Delivery Management System Local File Inclusion (LFI) Scanner

The Sangfor Application is commonly used by enterprises for managing and delivering applications securely and efficiently across networks. IT departments in medium to large organizations rely on this system to ensure optimized application performance and streamlined operations. It serves to manage user access, enforce security policies, and provide insights into application usage. The application is integral for environments requiring centralized application delivery and ensures that resources are allocated and managed effectively. Its use enhances security by centralizing control over application deliveries and access. Its capabilities are crucial for maintaining high standards of network performance and application security.

Configuration File Disclosure is a vulnerability that allows unauthorized individuals to access sensitive configuration files in a system. Such vulnerabilities can lead to the exposure of credentials, system configurations, and potentially sensitive data. It often occurs due to misconfigurations or lack of proper access control mechanisms. The risk associated with configuration file disclosure includes unauthorized access and potential escalation to more severe exploits. Understanding and mitigating this vulnerability is essential for maintaining the integrity and confidentiality of system operations. It's especially critical in applications handling sensitive data and controlling access to critical IT infrastructure.

In the case of Sangfor Application, the vulnerability occurs due to improper access controls on the sys_user.conf file. Unauthorized users can directly access this configuration file through a specific endpoint. When accessed, sensitive information such as account details and passwords can be exposed, compromising system security. The endpoint '/tmp/updateme/sinfor/ad/sys/sys_user.conf' is particularly vulnerable, and its exposure could lead to unauthorized access. The presence of specific keywords in the response body, such as "true", "admin", and XML tags, confirms the vulnerability. A successful exploit results in disclosure of system credentials.

Exploitation of this vulnerability can lead to unauthorized access to administrative accounts and potentially allow attackers to manipulate system configurations. An attacker could leverage the disclosed credentials to gain control over the application delivery management system. This could result in data breaches, unauthorized data modification, and interruptions to service delivery. The organization may face severe disruptions in their operations, financial losses, and reputational damage. In addition, there could be compliance violations due to unauthorized access to sensitive user information.
