Kiali versions prior to 1.15.1 contain a vulnerability where a hard-coded cryptographic key is used in the default configuration file. This key is used to sign JWT tokens for authentication. An attacker who knows the key can generate their own valid JWT tokens, bypassing authentication and potentially gaining unauthorized access to Kiali and the underlying Istio configuration.

This repository is a proof-of-concept (PoC) exploit for CVE-2020-1764, targeting Kiali versions 0.4.0 to 1.15.0 when configured with the 'login' authentication strategy. The exploit leverages a static JWT signing key ('kiali') to generate a valid JWT token for the 'admin' user. The repository contains two files: a README.md with usage instructions and endpoint information, and poc.go, a Go program that creates a JWT token with 'admin' privileges. The exploit allows an attacker to bypass authentication and access the Kiali API as an administrator by presenting the forged token. The attack vector is network-based, requiring access to the Kiali API endpoints. No detection scripts or fake elements are present; the code is a functional PoC for authentication bypass.
