CVE-2020-5284 Scanner

Next.js is a popular open-source framework used by developers for building server-side rendered React applications. It allows developers to create scalable applications easily without the need for complex configuration. Next.js offers features such as automatic code splitting, static site generation, and server-side rendering, making it an ideal choice for both small and large-scale applications.

However, a recent vulnerability, CVE-2020-5284, has been detected in Next.js versions before 9.3.2. This vulnerability allows attackers to craft special requests to access files in the dist directory. The dist directory (.next) typically contains build assets, but in some cases, it can also contain other assets. Attackers can exploit the vulnerability to gain unauthorized access to these files.

The exploitation of this vulnerability can lead to severe consequences for businesses and organizations. Attackers can use the information obtained from the files to compromise the security of the application or network. They can exfiltrate confidential data, install malware, or even take control of the application altogether. The result can be a complete compromise of the system.
