CVE-2010-3901

Estado: ModificadaMedia (6.4)—

OpenConnect before 2.25 does not properly validate X.509 certificates, which allows man-in-the-middle attackers to spoof arbitrary AnyConnect SSL VPN servers via a crafted server certificate that (1) does not correspond to the server hostname or (2) is presented in circumstances involving a missing --cafile configuration option.
