Cisco WebEx Meetings Server User Enumeration Vulnerability

A vulnerability in the Forgot Password process of the Cisco WebEx Meetings Server could allow an unauthenticated, remote attacker to enumerate a valid administrator account.

The vulnerability is due to insufficient user input validation. An attacker could exploit this vulnerability by submitting crafted packets to a vulnerable device.

Cisco has confirmed the vulnerability in a security notice and released updated software.

To exploit the vulnerability, the attacker may need access to trusted or internal networks to transmit crafted packets to the targeted system. This access requirement could limit the likelihood of a successful exploit.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
