How to fix?
org.apache.httpcomponents:httpclient to version 4.2.3 or higher.
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.
