CyberRota Analysis

AI-Generated

The dbx database client is vulnerable due to improper authentication handling in its web component, allowing unauthenticated attackers to access sensitive API endpoints and execute arbitrary SQL commands. This could lead to unauthorized data disclosure, modification, or destruction in connected databases, particularly in deployments where the DBX_PASSWORD is unset. Organizations using dbx versions prior to 0.5.51 should prioritize upgrading to mitigate this critical risk.

Original NVD Description

dbx is a cross-platform database client for databases. Prior to 0.5.51, dbx-web auth_middleware in crates/dbx-web/src/auth.rs passes every protected request to the handler chain when password_hash is None. A fresh deployment reaches that state when DBX_PASSWORD is unset and no stored password exists, while crates/dbx-web/src/main.rs binds the service to 0.0.0.0 on port 4224 by default. An unauthenticated network attacker can call the /api/connection/connect and /api/query/execute routes to use configured database credentials and execute arbitrary SQL, allowing disclosure, modification, or destruction of data in connected databases. The desktop Tauri application is not affected because it binds only to loopback. This issue is fixed in version 0.5.51.
