Version Summary:IntelliShield has updated this alert to indicate that software updates are available for the Cisco Unified Communications Manager role bypass vulnerability.
 
 
Description
A vulnerability in the administration portal of Cisco Unified Communications Manager (Unified CM) could allow an authenticated, remote attacker to bypass role restrictions.

The vulnerability is due to insufficient role restriction processing. An attacker could exploit this vulnerability by revisiting the link to a previously denied location of the administration portal. An exploit could allow the attacker to access sections of the administration portal to which the attacker does not have role-based access.

Cisco has confirmed the vulnerability in a security notice and released software updates.
 
Warning Indicators
At the time this alert was first published, Cisco Unified CM versions 9.1(2.10000.28) and prior were vulnerable. Later releases of Cisco Unified CM may also be vulnerable.
 
IntelliShield Analysis
To exploit this vulnerability, an attacker must authenticate to a targeted device. This access requirement reduces 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.
