CyberRota Analysis

AI-Generated

The Tilt HUD HTTP server in versions 0.20.8 to 0.37.3 of Kubernetes is vulnerable due to the absence of authentication middleware, allowing unauthenticated network callers to manipulate developer-defined resources and access sensitive engine state information, including session tokens. This could lead to unauthorized actions against the Kubernetes environment, posing significant risks to application integrity and security. Organizations using affected versions of Tilt should prioritize upgrading to version 0.37.4 to mitigate these vulnerabilities.

Original NVD Description

Tilt defines dev environments as code for microservice apps on Kubernetes. From 0.20.8 through 0.37.3, the Tilt HUD HTTP server registers handlers on a gorilla/mux router with no authenticating middleware. When the HUD is bound to a non-loopback address, an unauthenticated network caller can trigger developer-defined resources, tamper with Tiltfile arguments, read full engine state including the session token, and invoke apiserver resources through the token-attaching /proxy handler. This issue is fixed in version 0.37.4.
