Sprockets is a widely popular Ruby on Rails asset pipeline responsible for compiling and serving JavaScript, CSS, and images. It is used to manage and optimize the static assets of a website or application, improving both performance and maintainability. This seamless tool is implemented in various frameworks and applications using Ruby and procures great flexibility and convenience.
However, Sprockets has been found to have an information leak vulnerability that can be exploited by specially crafted requests. This vulnerability is identified with the code CVE-2018-3760 and affects versions 4.0.0.beta7 and lower, 3.7.1 and lower, and 2.12.4 and lower of Sprockets. The vulnerability allows an attacker to access files that exist on the filesystem outside an application's root directory when the Sprockets server is used in production.
When this vulnerability is exploited, it can lead to unauthorized access to sensitive data or files outside the application's defenses. It can allow an attacker to steal data, manipulate files, or carry out other malicious actions that can compromise the security of the website or application. Additionally, an attacker can use the information they obtain to compromise other systems connected to the target website or application.

To protect against this vulnerability, it is advisable to take the following precautions:
- Upgrade Sprockets to the latest version as soon as possible.
- Ensure that the web server is not running in production mode.
- Set the `config.assets.compile` configuration option to false.
- Use a web application firewall to monitor and filter malicious requests.
- Implement least privilege access privileges to ensure that the server has limited access to files and directories.
