CVE-2020-8172: TLS session reuse can lead to host certificate verification bypass

Published Jun 2, 2020
·
Updated

A TLS Hostname verification bypass vulnerability exists in NodeJS. This flaw allows an attacker to bypass TLS Hostname verification when a TLS client reuses HTTPS sessions.

Other sources

The 'session' event could be emitted before the 'secureConnect' event. It should not be, because the connection may fail to be authorized. If it was saved an authorized connection could be established later with the session ticket. Note that the https agent caches sessions, so is vulnerable to this.

The 'session' event will now only be emitted after the 'secureConnect' event, and only for authorized connections.

Does not affect Node.js 10.x.

— Node.Js

TLS session reuse can lead to host certificate verification bypass in node version < 12.18.0 and < 14.4.0.
