#VU21783 Inconsistent interpretation of HTTP requests in Go programming language - CVE-2015-5739

The vulnerability allows a remote attacker to conduct an HTTP request smuggling attack on the target system.

The vulnerability exists due to the "net/http" library in "net/textproto/reader.go" does not properly parse HTTP header keys. A remote attacker can send a specially crafted HTTP request and conduct HTTP request smuggling attacks via a space instead of a hyphen, as demonstrated by "Content Length" instead of "Content-Length."
