Name of the Vulnerable Software and Affected Versions
curl (affected versions not specified)
Description
An HTTP proxy can trick libcurl into sending the origin's credentials, such as Basic passwords or Negotiate/Kerberos tickets, directly to the proxy. This occurs when the proxy responds to a
CONNECT tunnel request with a 401 WWW-Authenticate: status instead of the expected 407 Proxy-Authenticate: status.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
