A vulnerability in the web framework code of Cisco WebEx Meetings Server could allow an unauthenticated, remote attacker to perform a cross-site request forgery (CSRF) attack.
The vulnerability is due to insufficient CSRF protections. An attacker could exploit this vulnerability by convincing the user of the affected system to follow a malicious link or visit an attacker-controlled website.
Cisco has confirmed the vulnerability and software updates are available.
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
