Description Murray McAllister 2013-12-17 20:14:42 EST

It was found that PyWBEM, a Python library for making CIM (Common Information Model) operations over HTTP using the WBEM CIM-XML protocol, failed to verify the URI matches the Subject of the certificate. This could allow a man-in-the-middle attacker to spoof an SSL server if they had a certificate that was valid for any domain name.
