CVE-2020-8660 (NVD)

2020-03-04

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.

Products Envoy
Type Insufficient Verification of Data Authenticity (CWE-345)
