When a .NET application using SocketsHttpHandler sends a request through a proxy that authenticates with basic credentials and the response is an HTTP redirect, the Proxy-Authorization header can be incorrectly retained and forwarded with the redirected request, leaking the basic proxy credentials to the destination server. This allows an unauthorized remote attacker to disclose sensitive proxy authentication information over a network. Red Hat rates this flaw Moderate severity with a CVSS 3.1 base score of 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N), consistent with the upstream assessment.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
