Miggo AIRoot Cause Analysis

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

  1. ProxyServer.addAuthorizationHeader: Directly handles proxy auth headers in AsyncHttpClient (used by Play-WS).
  2. AhcWSClientConfig.buildProxyServer: Configures proxy credentials at the Play-WS/AHC integration layer.
  3. 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.
