Vulnerability from variot

Cisco WebEx 4.1 on iOS does not 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 an arbitrary valid certificate, aka Bug ID CSCud94176. Cisco WebEx for iOS is prone to a security-bypass vulnerability. Successfully exploiting this issue allows attackers to perform man-in-the-middle attacks or impersonate trusted servers which will aid further attacks. Cisco WebEx for iOS 4.1 is vulnerable; other versions may also be affected. Cisco WebEx is a set of Web conferencing tools developed by American Cisco (Cisco), which can assist office workers in different places to coordinate and cooperate. WebEx services include Web conferencing, telepresence video conferencing and enterprise instant messaging (IM)
