CyberRota Analysis
AI-GeneratedThe AsyncHttpClient library in affected versions of Exchange and Java is vulnerable due to the use of ThreadLocalRandom for generating HTTP Digest client nonces, compromising the unpredictability required for secure authentication. This flaw could allow attackers to exploit predictable nonces, potentially leading to credential precomputation and chosen-plaintext attacks. Organizations using these versions should prioritize upgrading to versions 3.0.12 or 2.16.1 to mitigate this low-severity vulnerability.

Original NVD Description
The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.12 and 2.16.1, Realm.Builder generates the HTTP Digest client nonce with ThreadLocalRandom rather than a cryptographically secure random source. Digest relies on an unpredictable cnonce to resist chosen-plaintext and credential precomputation attacks, so an observer able to infer generator state can reduce the protection of the authentication exchange. This issue is fixed in versions 3.0.12 and 2.16.1.
