FreeBSD : go -- net/http/cgi, net/http/fcgi: XSS (XSS) when Content-Type is not specified (67b050ae-ec82-11ea-9071-10c37b4ac2ea)

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Go project reports :

When a Handler does not explicitly set the Content-Type header, both CGI implementations default to 'text/html'. If an attacker can make a server generate content under their control (e.g. a JSON containing user data or an uploaded image file) this might be mistakenly returned by the server as 'text/html'. If a victim visits such a page they could get the attacker's code executed in the context of the server origin.
