CVE-2016-6286 (GCVE-0-2016-6286)

Vulnerability from cvelistv5 – Published: 2017-01-10 15:00 – Updated: 2024-08-06 01:22

Summary

The "spiffy-cgi-handlers" egg would convert a nonexistent "Proxy" header to the HTTP_PROXY environment variable, which would allow attackers to direct CGI programs which use this environment variable to use an attacker-specified HTTP proxy server (also known as a "httpoxy" attack). This affects all versions of spiffy-cgi-handlers before 0.5.

Severity

No CVSS data available.
