CVE-2012-6153

EPSS 1.2%

Improper certificate validation in org.apache.httpcomponents:httpclient

Published: 10/17/2018Modified: 4/28/2026

Description

http/conn/ssl/AbstractVerifier.java in Apache Commons HttpClient before 4.2.3 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.
