Northern.tech Mender Enterprise Server before 4.1.1 has Incorrect Access Control.

Mender Client Signature Verification Bypass

Northern.tech Mender Client 5 before 5.0.4 allows a Cryptographic signature verification bypass.

Directory Traversal Vulnerability in Mender Server Versions Up to 4.1.0

Northern.tech Mender Server v4.1.0, v4.0.1 and below, and fixed in v4.1.1 and v4.0.2 allows Directory Traversal.

Northern.tech Mender Enterprise before 3.6.4 and 3.7.x before 3.7.4 has Weak Authentication.

Northern.tech Mender 3.3.x before 3.3.2, 3.5.x before 3.5.0, and 3.6.x before 3.6.0 has Incorrect Access Control and allows users to change their roles and could allow privilege escalation from a low-privileged read-only user to a high-privileged user.

Northern.tech Mender before 3.6.6 and 3.7.x before 3.7.7 allows SSRF.

Northern.tech Mender before 3.6.5 and 3.7.x before 3.7.5 has Incorrect Access Control.

The client in Northern.tech Mender 3.2.0, 3.2.1, and 3.2.2 has Incorrect Access Control. It listens on a random, unprivileged TCP port and exposes an HTTP proxy to facilitate API calls from additional client components running on the device. However, it listens on all network interfaces instead of only the localhost interface. Therefore, any client on the same network can connect to this TCP port and send HTTP requests. The Mender Client will forward these requests to the Mender Server. Additionally, if mTLS is set up, the Mender Client will connect to the Mender Server using the device's client certificate, making it possible for the attacker to bypass mTLS authentication and send requests to the Mender Server without direct access to the client certificate and related private key. Accessing the HTTP proxy from the local network doesn't represent a direct threat, because it doesn't expose any device or server-specific data. However, it increases the attack surface and can be a potential vector to exploit other vulnerabilities both on the Client and the Server.

The iot-manager microservice 1.0.0 in Northern.tech Mender Enterprise before 3.2.2 allows SSRF because the Azure IoT Hub integration provides several SSRF primitives that can execute cross-tenant actions via internal API endpoints.

The Deviceconnect microservice through 1.3.0 in Northern.tech Mender Enterprise before 3.2.2. allows Cross-Origin Websocket Hijacking.

The useradm service 1.14.0 (in Northern.tech Mender Enterprise 2.7.x before 2.7.1) and 1.13.0 (in Northern.tech Mender Enterprise 2.6.x before 2.6.1) allows users to access the system with their JWT token after logout, because of missing invalidation (if the JWT verification cache is enabled).
