Improper Validation of Certificate with Host Mismatch


Severity Medium
Score 5.8/10


The getCN function in Apache Axis 1.4 and earlier 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-2012-5784.
