Description (partial)

A vulnerability in training registration page in Cisco WebEx Training Center could allow an unauthenticated, remote attacker to enumerate e-mail 
addresses of registered attendees.

The vulnerability is due to registration error messages that reveal when the e-mail address supplied during registration has already been specified by 
another registered attendee. An attacker could exploit this vulnerability by submitting multiple registration requests, and viewing the resulting error 
messages to determine which e-mail addresses have been submitted by other registered attendees.
