Описание

A flaw was found in curl. This vulnerability allows curl to wrongly reuse an existing HTTP proxy connection when performing a CONNECT request to a server, even if the new request uses different authentication credentials for the HTTP proxy. This improper connection reuse could lead to an attacker gaining unauthorized access to resources or information intended for a different user.

Меры по смягчению последствий

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

curl would wrongly reuse an existing HTTP proxy connection doing CONNECT to a server, even if the new request uses different credentials for the HTTP proxy. The proper behavior is to create or use a separate connection.
