CVSS: 8.2EPSS: 0%CPEs: 1EXPL: 0CVE-2021-21378 – JWT authentication bypass with unknown issuer token
https://notcve.org/view.php?id=CVE-2021-21378
11 Mar 2021 — Envoy is a cloud-native high-performance edge/middle/service proxy. In Envoy version 1.17.0 an attacker can bypass authentication by presenting a JWT token with an issuer that is not in the provider list when Envoy's JWT Authentication filter is configured with the `allow_missing` requirement under `requires_any` due to a mistake in implementation. Envoy's JWT Authentication filter can be configured with the `allow_missing` requirement that will be satisfied if JWT is missing (JwtMissed error) and fail if J... • https://github.com/envoyproxy/envoy/commit/ea39e3cba652bcc4b11bb0d5c62b017e584d2e5a • CWE-287: Improper Authentication CWE-303: Incorrect Implementation of Authentication Algorithm •

15 Dec 2020 — Envoy before 1.16.1 logs an incorrect downstream address because it considers only the directly connected peer, not the information in the proxy protocol header. This affects situations with tcp-proxy as the network filter (not HTTP filters). Envoy versiones anteriores a 1.16.1, registra una dirección posterior incorrecta porque considera solo al peer conectado directamente, no la información en el encabezado proxy protocol. Esto afecta situaciones con tcp-proxy como filtro de red (no filtros HTTP) • https://github.com/envoyproxy/envoy/compare/v1.16.0...v1.16.1 •
