The HTTP clients in the (1) httplib, (2) urllib, (3) urllib2, and (4) xmlrpclib libraries in CPython (aka Python) 2.x before 2.7.9 and 3.x before 3.4.3, when accessing an HTTPS URL, do not (a) check the certificate against a trust store or verify that the server hostname matches a domain name in the subject's (b) Common Name or (c) subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate. Los clientes HTTP en las librarias (1) httplib, (2) urllib, (3) urllib2, and (4) xmlrpclib en CPython (también conocido como Python) 2.x anterior a 2.7.9 y 3.x anterior a 3.4.3, cuando accede a una URL HTTPS, not (a) comprueba el certificado contra un almacen trust o verifica que elnombre del servidor coincide con un nombre de dominio en el campo del tema (b) Common Name o (c) subjectAltName del certificado X.509, lo que permite a atacantes man-in-the-middle falsificar servidores SSL a través de un certificado válido arbitrario. The Python standard library HTTP client modules (such as httplib or urllib) did not perform verification of TLS/SSL certificates when connecting to HTTPS servers. A man-in-the-middle attacker could use this flaw to hijack connections and eavesdrop or modify transferred data. • http://bugs.python.org/issue22417 http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://www.openwall.com/lists/oss-security/2014/12/11/1 http://www.oracle.com/technetwork/topics/security/bulletinjan2015-2370101.html http://www.oracle.com/technetwork/topics/security/bulletinoct2015-2511968.html http://www.securityfocus.com/bid/71639 https://access.redhat.com/errata/RHSA-2016:1166 https://access.redhat.com/errata/RHSA-2017:1162 https://access.redhat.com/errata&#x • CWE-345: Insufficient Verification of Data Authenticity •
