F5 NGINX Controller

In versions 3.0.0-3.9.0, 2.0.0-2.9.0, and 1.0.1, the NGINX Controller Agent does not use absolute paths when calling system utilities.

In NGINX Controller 3.3.0-3.4.0, undisclosed API endpoints may allow for a reflected Cross Site Scripting (XSS) attack. If the victim user is logged in as admin this could result in a complete compromise of the system.

In versions 3.0.0-3.4.0, 2.0.0-2.9.0, and 1.0.1, there is insufficient cross-site request forgery (CSRF) protections for the NGINX Controller user interface.

In NGINX Controller versions prior to 3.2.0, an unauthenticated attacker with network access to the Controller API can create unprivileged user accounts. The user which is created is only able to upload a new license to the system but cannot view or modify any other components of the system.

On versions 3.0.0-3.3.0, the NGINX Controller webserver does not invalidate the server-side session token after users log out.

In versions prior to 3.3.0, the NGINX Controller Agent installer script 'install.sh' uses HTTP instead of HTTPS to check and install packages

On NGINX Controller versions 3.1.0-3.3.0, AVRD uses world-readable and world-writable permissions on its socket, which allows processes or users on the local system to write arbitrary data into the socket. A local system attacker can make AVRD segmentation fault (SIGSEGV) by writing malformed messages to the socket.

The NGINX Controller 2.0.0 thru 2.9.0 and 3.x before 3.15.0 Administrator password may be exposed in the systemd.txt file that is included in the NGINX support package.

In NGINX Controller 3.0.0-3.4.0, recovery code required to change a user's password is transmitted and stored in the database in plain text, which allows an attacker who can intercept the database connection or have read access to the database, to request a password reset using the email address of another registered user then retrieve the recovery code.

In versions 3.0.0-3.5.0, 2.0.0-2.9.0, and 1.0.1, the Neural Autonomic Transport System (NATS) messaging services in use by the NGINX Controller do not require any form of authentication, so any successful connection would be authorized.

In versions 3.0.0-3.5.0, 2.0.0-2.9.0, and 1.0.1, the NGINX Controller installer starts the download of Kubernetes packages from an HTTP URL On Debian/Ubuntu system.

In versions of NGINX Controller prior to 3.2.0, communication between NGINX Controller and NGINX Plus instances skip TLS verification by default.

Intra-cluster communication does not use TLS. The services within the NGINX Controller 3.x before 3.4.0 namespace are using cleartext protocols inside the cluster.

In versions prior to 3.3.0, the NGINX Controller is configured to communicate with its Postgres database server over unencrypted channels, making the communicated data vulnerable to interception via man-in-the-middle (MiTM) attacks.

In versions 3.0.0-3.5.0, 2.0.0-2.9.0, and 1.0.1, when users run the command displayed in NGINX Controller user interface (UI) to fetch the agent installer, the server TLS certificate is not verified.

In versions of NGINX Controller prior to 3.3.0, the helper.sh script, which is used optionally in NGINX Controller to change settings, uses sensitive items as command-line arguments.

The NAAS 3.x before 3.10.0 API keys were generated using an insecure pseudo-random string and hashing algorithm which could lead to predictable keys.

The Nginx Controller 3.x before 3.7.0 agent configuration file /etc/controller-agent/agent.conf is world readable with current permission bits set to 644.
