request forgery attacks. Updates are not available.
Description
A vulnerability in Cisco Unified Customer Voice Portal (CVP) could allow an
unauthenticated, remote attacker to conduct cross-site request forgery (CSRF)
attacks.
The vulnerability is due to insufficient CSRF protections on an affected
system. An attacker could exploit this vulnerability by persuading a user on
the affected system to follow a malicious link or visit an attacker-controlled
website. A successful exploit could allow the attacker to perform unauthorized
actions via the web browser with the privileges of the user.
Cisco has confirmed the vulnerability; however, software updates are not
available.

user to a malicious site and use misleading language or instructions to
persuade the user to follow the provided link.

additional details and an up-to-date list of affected product versions.
Impact
