Cisco Security Advisory: Cisco Voice Operating System-Based Products Unauthorized Access Vulnerability
Advisory ID: cisco-sa-20171115-vos
For Public Release: 2017 November 15 16:00 GMT
Last Updated: 2017 November 15 16:00 GMT
CVE ID(s): CVE-2017-12337
CVSS Score v(3): 9.8 CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
A vulnerability in the upgrade mechanism of Cisco collaboration products based on the Cisco Voice Operating System software platform could allow an unauthenticated, remote attacker to gain unauthorized, elevated access to an affected device.
The vulnerability occurs when a refresh upgrade or Prime Collaboration Deployment (PCD) migration is performed on an affected device. When a refresh upgrade or PCD migration is completed successfully, an engineering flag remains enabled and could allow root access to the device with a known password.
If the vulnerable device is subsequently upgraded using the standard upgrade method to an Engineering Special Release, service update, or a new major release of the affected product, this vulnerability is remediated by that action.
Note: Engineering Special Releases that are installed as COP files, as opposed to the standard upgrade method, do not remediate this vulnerability.
An attacker who can access an affected device over SFTP while it is in a vulnerable state could gain root access to the device. This access could allow the attacker to compromise the affected system completely.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
