Blazor Boot File Disclosure

What is the "Blazor Boot File Disclosure?"

The "Blazor Boot File Disclosure" module is designed to detect a specific vulnerability in Blazor applications. Blazor is a web framework that allows developers to build interactive web UIs using C# instead of JavaScript. This module focuses on the exposure of sensitive configuration information through the "blazor.boot.json" file.

This vulnerability can have an informative impact, providing potential attackers with access to sensitive configuration details that could be used to exploit the application further.

Impact

The "Blazor Boot File Disclosure" module aims to identify instances where the "blazor.boot.json" file is accessible and contains sensitive configuration information. If this vulnerability is present, it could potentially expose sensitive data, such as API keys, database credentials, or other configuration details, to unauthorized individuals.

How the module works?

The "Blazor Boot File Disclosure" module works by sending an HTTP GET request to the "/_framework/blazor.boot.json" path. It then applies matching conditions to determine if the response contains specific keywords, such as "Blazor" and "\"config\":". If both conditions are met, the module flags the vulnerability.

Here is an example of the HTTP request sent by the module:

GET /_framework/blazor.boot.json

The matching conditions ensure that the response contains both the term "Blazor" and the keyword "\"config\":". If these conditions are satisfied, the module identifies the presence of the vulnerability.

This module is part of the Vidoc platform, which utilizes multiple modules to perform comprehensive scanning and detection of various misconfigurations, vulnerabilities, and software fingerprints.
