Caucho Resin is a web server and Java application server used for serving web applications and related services. It is widely utilized in the enterprise sector for its performance and scalability, catering to web environments with significant traffic and resource demands. Developers and IT professionals utilize this server for running Java EE applications, given its support for multiple configurations and integrations. Resin can be implemented in both on-premises and cloud-based environments, accommodating various deployment needs. It is often chosen for its fast iteration capabilities and stability, which are vital for mission-critical applications. Overall, it serves as a robust platform for executing Java-based web solutions and services.
The Local File Inclusion (LFI) vulnerability allows attackers to include files on a server through the web browser. This is a significant risk as it can potentially expose sensitive files that should not be accessible to unauthorized users. Typically, attackers exploit this vulnerability by manipulating input parameters in HTTP requests. LFI vulnerabilities often occur due to inadequate input validation, where the application fails to properly validate file paths or access. Attackers may leverage LFI to execute local scripts, gather sensitive data, or access configuration files that reveal server information. Such vulnerabilities pose significant security risks, leading to unauthorized file access and potential data breaches.
In the specific implementation of the Caucho Resin server, an LFI vulnerability exists within a CGI program. The vulnerability involves inadequate input verification in the file retrieval process of the "/resin-doc/viewfile" endpoint. This flaw permits attackers to craft HTTP requests that can read arbitrary files from the server's home directory. The vulnerable parameter appears to be within the request query, as indicated by the 'file' parameter. Exploitation can lead to unauthorized access to JSP source codes, server configuration files, and even bytecode files, if not properly secured.
If malicious actors exploit this vulnerability, they could gain unauthorized access to sensitive server files. This could result in leakage of intellectual property, such as source code, or expose sensitive server functionalities and configurations to attackers. Additionally, an attacker might use this vulnerability to further exploit the system or gain a foothold within the server's environment for additional attacks. The compromise of such a server could impact both the integrity and confidentiality of the hosting environment, potentially leading to a full system compromise over time.
