Version Summary: Cisco Unity Connection contains a vulnerability that could
allow an unauthenticated, remote attacker to conduct cross-site request
forgery attacks. Updates are available.
A vulnerability in the CUCReports page of Cisco Unity Connection could allow
an unauthenticated, remote attacker to perform a cross-site request forgery
(CSRF) attack against the CUCReports web interface.
The vulnerability is due to insufficient CSRF protections on the Cisco Unity
Connection web interface. An attacker could exploit this vulnerability by
persuading an authenticated user of the affected system to follow a malicious
link or visit an attacker-controlled website.
Cisco has confirmed the vulnerability and released software updates.
At the time this alert was first published, Cisco Unity Connection versions
11.0(0.98000.225) and 11.0(0.98000.332) were vulnerable. Other versions may
also be affected.
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
convince the user to follow the link.
Cisco indicates through the CVSS score that functional exploit code exists;
however, the code is not known to be publicly available.
Cisco has released bug ID CSCut33659 for registered users that contains
additional details and an up-to-date list of affected product versions.
An unauthenticated, remote attacker could exploit this vulnerability to take
unauthorized actions via the web browser with the privileges of the user. A
successful exploit could allow the attacker to conduct further attacks.
The vulnerability is due to insufficient CSRF protections on an affected
An attacker could exploit this vulnerability by convincing a user of an
