Description
Envoy Gateway is an open source project for managing Envoy Proxy as a standalone or Kubernetes-based application gateway. Prior to 1.5.7 and 1.6.2, EnvoyExtensionPolicy Lua scripts executed by Envoy proxy can be used to leak the proxy's credentials. These credentials can then be used to communicate with the control plane and gain access to all secrets that are used by Envoy proxy, e.g. TLS private keys and credentials used for downstream and upstream communication. This vulnerability is fixed in 1.5.7 and 1.6.2.
Analysis
Credential theft via Lua script execution in Envoy Gateway versions before 1.5.7 and 1.6.2 allows authenticated attackers to extract proxy credentials and subsequently access the control plane and all associated secrets including TLS private keys. Public exploit code exists for this vulnerability. …
