CVE-2020-8660 (GCVE-0-2020-8660)

Vulnerability from cvelistv5 – Published: 2020-03-04 21:10 – Updated: 2024-08-04 10:03

Summary

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.

Severity

No CVSS data available.
