CVE-2016-6287 (GCVE-0-2016-6287)

Vulnerability from cvelistv5 – Published: 2017-01-10 15:00 – Updated: 2024-08-06 01:22
VLAI
Summary
The "http-client" egg always used a HTTP_PROXY environment variable to determine whether HTTP traffic should be routed via a proxy, even when running as a CGI process. Under several web servers this would mean a user-supplied "Proxy" header could allow an attacker to direct all HTTP requests through a proxy (also known as a "httpoxy" attack). This affects all versions of http-client before 0.10.
