CWE-345

Description

CNCF Envoy through 1.13.0 TLS inspector bypass. TLS inspector could have been bypassed (not recognized as a TLS client) by a client using only TLS 1.3. Because TLS extensions (SNI, ALPN) were not inspected, those connections might have been matched to a wrong filter chain, possibly bypassing some security restrictions in the process.

Affected configurations

• envoyproxy envoy (< 1.12.3) • envoyproxy envoy (>= 1.13.0 < 1.13.1)
