How to fix?

Upgrade org.apache.httpcomponents:httpclient to version 4.2.3 or higher.

Overview

org.apache.httpcomponents:httpclient is a HttpClient component of the Apache HttpComponents project.

Affected versions of this package are vulnerable to Man-in-the-Middle (MitM) due to not verifing the requesting server's hostname agains existing domain names in the SSL Certificate. The AbstractVerifier does not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a certificate with a subject that specifies a common name in a field that is not the CN field.

NOTE: this issue exists because of an incomplete fix for CVE-2012-5783.
