CVE-2012-6153

Status Candidate

Overview

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.

It was found that the fix for CVE-2012-5783 was incomplete: the code added to check that the server host name matches the domain name in a subject's Common Name field in X.509 certificates was flawed. A man-in-the-middle attacker could use this flaw to spoof an SSL server using a specially crafted X.509 certificate. It was discovered that the HttpClient incorrectly extracted host name from an X.509 certificate subject's Common Name field. A man-in-the-middle attacker could use this flaw to spoof an SSL server using a specially crafted X.509 certificate.
