Vulnerability Data

The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.1.0 until 2.16.1 and 3.0.12, requests using an authenticated SOCKS proxy can expose the proxy's credentials to the origin because NettyRequestFactory and…

more

NettyRequestSender attach Proxy-Authorization without confirming that the request is being sent to an HTTP proxy. With preemptive proxy authentication, the header is attached to a plaintext HTTP request, exposing credentials such as directly reversible Basic credentials to the origin. With the default non-preemptive flow, a hostile origin can return a 407 response and ProxyUnauthorized407Interceptor sends the proxy credentials through the existing SOCKS tunnel, including NTLM, Kerberos, and SPNEGO credentials. Releases before 2.1.0 lack SOCKS proxy support. This issue is fixed in versions 2.16.1 and 3.0.12.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-319 CWE-522

Sensitive values are moved off the primary channel, avoiding cleartext transmission risks associated with that channel.

addresses: CWE-522

Training instructs users on protecting credentials from disclosure or unauthorized access.

addresses: CWE-319

Role-based training covers secure transmission methods, mitigating cleartext transmission of sensitive data.

addresses: CWE-522

Training records for security awareness and role-based training verify education on credential protection practices, tangibly reducing risks from mishandling or exposing credentials.

addresses: CWE-319

By requiring documented security controls for information exchanges, the control reduces the risk of cleartext transmission of sensitive data.

addresses: CWE-319

Mapping transmission actions in data flows helps prevent cleartext transmission of sensitive information.

addresses: CWE-319

Settings can enforce secure transmission protocols to prevent cleartext transmission of sensitive data.

addresses: CWE-522

Protecting authenticator content from unauthorized disclosure and modification while requiring protective controls addresses insufficiently protected credentials.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-01 partial match
prevents

Credential management practices directly reduce insecure storage/transmission but do not guarantee encryption or transport protection.

PR.AA-03 partial match
prevents

Authentication policies can enforce stronger credential handling yet address only verification, not storage or transit protection.

PR.AA-04 partial match
prevents

Protecting identity assertions covers conveyance of credentials but is narrower than full credential lifecycle protection.

PR.DS-01 partial match
prevents

Encrypting data-at-rest fully prevents insecure credential storage while only partially satisfying the broader data-protection outcome.

PR.DS-02 partial match
prevents

Encryption of data-in-transit directly prevents cleartext transmission while the control also addresses integrity and availability.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Acceptable-use expectations that cover protection of credentials and information assets throughout their lifecycle discourage practices that expose or mishandle authentication material.

prevents

Mandating cryptographic protection and stronger authentication on public networks stops the transmission of plaintext sensitive information.

prevents

Requiring protected storage, transmission, and non-display of passwords prevents credentials from being stored or sent in clear text where they can be harvested by unauthorized actors.

prevents

Contractual clauses that survive termination help ensure that credentials and other secrets are not retained or misused after employment ends.

prevents

Regular reminders about password security and personal accountability make users less likely to store or transmit credentials in cleartext or other unprotected forms.

mitigates

By requiring signatories to protect credentials and other authentication material under the same confidentiality terms, the control discourages the mishandling or exposure of credentials that could lead to unauthorized account access.
