Vulnerability description
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Privoxy before 3.0.21 does not properly handle Proxy-Authenticate and Proxy-Authorization headers in the client-server data stream, which makes it easier for remote HTTP servers to spoof the intended proxy service via a 407 (aka Proxy Authentication Required) HTTP status code.
Remediation
Install update from vendor's website.
