Short explanation
Prior to version 0.29.0, the Warpgate Kubernetes protocol listener discloses internal error text and diagnostics to unauthenticated callers.
An unauthenticated network client can receive ASN.1/DER or database errors without the attempt being recorded in gateway logs.
What should be done?
- Upgrade to version 0.29.0 or later
- Follow vendor security advisories
Chain of evidence and sources
Warpgate 0.29.0 öncesi sürümlerde Kubernetes protokol dinleyicisi kimliği doğrulanmamış çağrılara dahili hata metinleri sızdırmaktadır.
Ifşa olan bilgiler dahili tanılama ile sınırlıdır ve kullanıcı verisi, bütünlük veya erişilebilirlik etkisi bulunmamaktadır.
Show the technical text from the sources
Warpgate is an open source SSH, HTTPS, and MySQL bastion host for Linux. Prior to 0.29.0, the Kubernetes protocol listener uses AcceptAnyClientCert in warpgate-protocol-kubernetes/src/server/client_certs.rs to accept certificates at the TLS layer and defer validation to warpgate-protocol-kubernetes/src/server/auth.rs, where authentication and lookup failures are rendered verbatim in an HTTP 500 response body. The Kubernetes application in warpgate-protocol-kubernetes/src/server/mod.rs lacks the outer request-logging wrapper used by the HTTP protocol, and failures in warpgate-protocol-kubernetes/src/server/handlers.rs can short-circuit before its inner log point. An unauthenticated network client can therefore induce failures and receive ASN.1/DER parser diagnostics or sea_orm database errors without the attempt being recorded in the gateway log. The disclosed information is limited to internal diagnostics, and no user-data, integrity, or availability impact is established. This issue is fixed in version 0.29.0.
