NVD Description

Note: Versions mentioned in the description apply only to the upstream servicemesh-proxy package and not the servicemesh-proxy package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
