Meteor subdomain takeover

What is the "Meteor subdomain takeover?"

The "Meteor subdomain takeover" module is designed to detect the possibility of a subdomain takeover vulnerability in websites that use the Meteor framework. This vulnerability can have a high severity level, potentially allowing an attacker to take control of a subdomain and exploit it for malicious purposes.

Impact

If a subdomain takeover vulnerability is present, an attacker could potentially gain unauthorized access to the subdomain and use it to host malicious content, launch phishing attacks, or perform other malicious activities. This can lead to reputational damage, loss of sensitive data, and compromise of user accounts.

How the module works?

The "Meteor subdomain takeover" module works by sending HTTP requests to the target website and analyzing the responses for specific patterns. It looks for the presence of the following string: 404 Not Found: No applications registered for host '. If this string is found, it indicates that the subdomain is not properly configured and may be vulnerable to takeover.

The module uses matching conditions to determine if the vulnerability is present. In this case, it checks if the response contains the specified string and considers it a match if it does. If a match is found, the module reports the vulnerability as a high severity issue.

It is important for website owners using the Meteor framework to ensure that their subdomains are properly configured to prevent potential takeover vulnerabilities. Regular security assessments and patching of any identified vulnerabilities are recommended to mitigate the risk of subdomain takeover.
