Summary

AsyncHttpClient's async-http-client library from 3.0.0.Beta1 before 3.0.13 and from 2.0.0 before 2.16.1 treats a Digest challenge with no usable nonce as a Basic challenge. A malicious origin server or proxy can send such a challenge, making the client resend the username and password with reversible Basic authentication, exposing them in cleartext. Both origin and proxy challenge parsing are affected.

Description from the CNA

The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.13 and 2.16.1, Realm.Builder treats a Digest challenge that yields no usable nonce as a Basic challenge. A malicious origin or proxy can label a challenge Digest while omitting or emptying the nonce, causing the client to resend the username and password using reversible Basic authentication. Both origin and proxy challenge parsers are affected. This issue is fixed in versions 3.0.13 and 2.16.1.
