CVE-2019-17598: Play Framework Inadequate Encryption Strength vulnerability

An issue was discovered in Lightbend Play Framework 2.5.x through 2.6.23. When configured to make requests using an authenticated HTTP proxy, play-ws may sometimes, typically under high load, when connecting to a target host using https, expose the proxy credentials to the target host.

Root Cause Analysis

The vulnerability stems from Play-WS improperly including proxy credentials in HTTP CONNECT requests during HTTPS tunneling. Key functions identified are:

ProxyServer.addAuthorizationHeader: Directly handles proxy auth headers in AsyncHttpClient (used by Play-WS).
AhcWSClientConfig.buildProxyServer: Configures proxy credentials at the Play-WS/AHC integration layer.
ChannelManager.createConnection: Manages connection reuse where credential leakage could occur under high load. These functions align with the described vulnerability mechanism (credentials in CONNECT requests) and Play Framework's architecture using AsyncHttpClient.
