CVE-2020-8660
CNCF Envoy through 1.13.0 TLS inspector bypass.
MEDIUM 5.3EPSS 0.61%
Does this matter?
Lower severity and a low EPSS score (0.61%). Track it; it rarely justifies an emergency change on its own.
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.
