Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-306: Missing Authentication for Critical Function, where the product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. In Frosh/adminer platform, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary Unauthenticated access to Adminer UI ### Details The Adminer route (/admin/adminer) was accessible without Shopware admin authentication. The route was configured with auth_required=false and performed no session validation, exposing the Adminer UI to unauthenticated users. Note: Database access itself requires credentials that are only set through the ACL-protected API endpoint. Direct database access without prior admin login is not possible through this vulnerability alone. ### Impact An unauthenticated user could access the Adminer interface, potentially disclosing version information or exploiting Adminer-specific vulnerabilities. ### Patches Version 2.2.1 adds session validation. The Adminer route now verifies an authenticated session flag before rendering — returning HTTP 403 otherwise. ### Workarounds Deactivate or uninstall the plugin.
