=========================================

Severity: Medium
Date    : 2020-09-03
CVE-ID  : CVE-2020-24553
Package : go
Type    : cross-site scripting
Remote  : Yes
Link    : https://security.archlinux.org/AVG-1215

Summary
=======

The package go before version 1.15.1-1 is vulnerable to cross-site
scripting.

Resolution
==========

Upgrade to 1.15.1-1.

# pacman -Syu "go>=1.15.1-1"

The problem has been fixed upstream in version 1.15.1.

Workaround
==========

None.

Description
===========

In Go versions before 1.15.1 and 1.14.8 if the Content-Type header of a
Handler was not explicitly set the net/http/cgi and net/http/fcgi
packages would default to “text/html”, which could cause a Cross-Site
Scripting vulnerability if an attacker can control any part of the
contents of a response.

Impact
======

A remote attacker is able to execute javascript or create html content
by sending specially crafted web content.
