Lynx does not verify that the servers certificate is signed by a trusted certification authority, which allows man-in-the-middle attackers to spoof SSL servers via a crafted certificate, related to improper use of a certain GnuTLS function.
Weakness
The product does not validate, or incorrectly validates, a certificate.
