Executive brief
9Router, an AI routing and token management tool, contains a critical security flaw in its database management interface. An attacker with basic access can export the entire system database, which contains sensitive information like API keys, login credentials, and OAuth tokens. Furthermore, they can overwrite the database with their own data, allowing them to change administrative passwords and take full control of the device and its connected AI services.
Technical details
The vulnerability exists in the /api/settings/database endpoint of 9Router prior to version 0.4.80. While the endpoint is protected by the ALWAYS_PROTECTED middleware, it only requires a valid JWT or CLI token and fails to implement secondary authentication for high-risk operations. An attacker with low-privileged access can perform a GET request to export the database (including plaintext API keys and OAuth tokens) or a POST request to import a malicious database. The import operation performs a complete wipe-and-replace of the existing database, allowing an attacker to overwrite the administrator's password hash and gain full control. The fix in version 0.4.80 introduces a requirement for the current dashboard password to be provided in the request headers or body for these operations.
