CVE-2012-6153 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 5.80% chance of exploitation in the next 30 days.
