How the Exploit Works
The vulnerability arises from the lack of authentication in certain GraphQL endpoints in the NPM package. This allows remote attackers to gain unauthorized access to these endpoints and obtain sensitive information. Attackers can exploit this vulnerability by sending specially crafted requests to these vulnerable endpoints.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited. This could be a sample HTTP POST request to a vulnerable GraphQL endpoint:
POST /graphql HTTP/1.1
Host: target.example.com
Content-Type: application/graphql
{
"query": "{ sensitiveInformation { ... } }"
}In this conceptual example, the attacker sends a malicious GraphQL query requesting sensitive information from the server. Due to the lack of proper authentication, the server might return the requested sensitive data.
Mitigation and Patching
To mitigate this vulnerability, users are advised to update the @evershop/evershop package to version 1.0.0-rc.8 or later, where the issue has been fixed. Until the patch can be applied, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure to detect and block exploit attempts.
