What is Caucho Resin LFR?

Caucho Resin LFR is a module that detects a vulnerability in the Caucho Resin software. This vulnerability allows remote unauthenticated users to exploit the 'inputFile' variable, which can be used to include the content of locally stored files and disclose their contents. The severity of this vulnerability is classified as high.


If exploited, this vulnerability can lead to unauthorized access to sensitive information stored on the server. Attackers can potentially view and disclose the contents of files that are not intended to be publicly accessible. This can result in the exposure of sensitive data, such as configuration files, source code, or other confidential information.

How the module works?

The Caucho Resin LFR module works by sending a specific HTTP request to the target server. The request includes a path parameter that allows the inclusion of arbitrary files using the 'inputFile' variable. The module then checks the response for specific conditions to determine if the vulnerability is present.

For example, the module checks if the response status code is 200, indicating a successful request. It also verifies the presence of a specific string in the response body, which indicates the inclusion of a vulnerable code snippet. If both conditions are met, the module flags the server as vulnerable to the Caucho Resin LFR vulnerability.

It is important to note that this module is designed to detect the vulnerability and does not attempt to exploit it further. Its purpose is to provide information about the presence of the vulnerability, allowing system administrators to take appropriate actions to mitigate the risk.
