Short explanation
A vulnerability exists in Telepresence where the Traffic Manager gRPC API lacks authentication, allowing unauthorized pods to claim an arbitrary namespace and intercept services.
This vulnerability allows attackers to obtain the victim pod's complete container environment, including secrets, tokens, and API keys, posing a critical threat to cluster security.
What should be done?
- Upgrade Telepresence to version 2.31.0
- Follow official vendor advisories
- Review network access controls
Chain of evidence and sources
Telepresence 2.31.0 öncesi sürümlerde Traffic Manager gRPC API'si kimlik doğrulaması istemez.
Herhangi bir pod rastgele bir yönetilen ad alanında kayıt oluşturabilir ve servis müdahalesi gerçekleştirebilir.
Saldırganlar kurban podun gizli anahtarlarını, jetonlarını ve API anahtarlarını içeren tüm ortamını elde edebilir.
Show the technical text from the sources
Telepresence enables local development against a remote Kubernetes or OpenShift cluster. Prior to 2.31.0, the Traffic Manager gRPC API on port 8081 accepts unauthenticated cluster-network callers, ArriveAsClient stores a caller-supplied Namespace using only the ManagesNamespace manager watchlist check, and CreateIntercept can target any managed namespace without checking the session's Kubernetes RBAC. An attacker operating any pod with network access to the manager can register in an arbitrary managed namespace, create service intercepts, receive intercepted traffic, and obtain the victim pod's complete container environment, including secrets, tokens, and API keys. The default cluster-wide deployment manages all namespaces. This vulnerability is fixed in 2.31.0.
