CVE-2024-55017
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAccount Takeover in Corezoid 6.6.0 in the OAuth2 implementation via an open redirect in the redirect_uri parameter allows attackers to intercept authorization codes and gain unauthorized access to victim accounts.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceCorezoid 6.6.0 contains an OAuth2 open redirect vulnerability in the redirect_uri parameter validation. Attackers can supply a malicious redirect_uri to intercept the authorization code during the OAuth2 authentication flow, then use that intercepted code to obtain access tokens and takeover victim accounts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Corezoid installationLocate the Corezoid application or service in your environment. This may be a web application, API service, or integrated component. Check installed software listings, running services, or application metadata for 'Corezoid'.Affected if Corezoid is not present in your environment
-
Check installed Corezoid versionDetermine the exact version number of your Corezoid installation. Look in application metadata, version files, package manager listings, or the admin interface for the version string. Compare it to 6.6.0.Affected if The installed version is exactly 6.6.0
-
Verify OAuth2 authentication is enabledInspect your Corezoid configuration to determine whether OAuth2 authentication flows are configured and active. Check authentication settings, OAuth2 client configurations, or authorization server settings.Affected if OAuth2 authentication is enabled and configured for user logins
-
Inspect redirect_uri validation configurationExamine the OAuth2 authorization endpoint configuration for redirect_uri validation logic. Look for settings that control URI validation during the authorization code flow. Check whether strict allowlist validation is implemented or if arbitrary URIs can be specified.Affected if redirect_uri validation is not strictly enforce allowlisted URIs, or validation can be bypassed
You are affected if Corezoid version 6.6.0 is installed AND OAuth2 authentication is enabled with permissive redirect_uri validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict allowlist-based validation for redirect_uri in the OAuth2 authorization endpoint, ensuring only pre-registered URIs are accepted.
