CVE

CVE-2012-2993

TITLE

Windows Phone 7 does not check certificate Common Names when sending or receiving emails over SSL.

Trust: 0.8

sources: CERT/CC: VU#389795

DESCRIPTION

Microsoft Windows Phone 7 does not verify the domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof an SSL server for the (1) POP3, (2) IMAP, or (3) SMTP protocol via an arbitrary valid certificate. Microsoft Windows Phone 7 is a smartphone from Microsoft. Successfully exploiting this issue allows attackers to perform man-in-the-middle attacks or impersonate trusted servers, which will aid further attacks
