CWE-798

Summary

A vulnerability in Cisco Prime Collaboration Provisioning (PCP) Software could
allow an unauthenticated, local attacker to log in to the underlying Linux
operating system.
The vulnerability is due to a hard-coded account password on the system. An
attacker could exploit this vulnerability by connecting to the affected system
via Secure Shell (SSH) using the hard-coded credentials. A successful exploit
could allow the attacker to access the underlying operating system as a low-
privileged user. After low-level privileges are gained, the attacker could
elevate to root privileges and take full control of the device.
Note: Although this vulnerability has a Common Vulnerability Scoring System
(CVSS) Base score of 5.9, which is normally assigned a Security Impact Rating
(SIR) of Medium, there are extenuating circumstances that allow an attacker to
elevate privileges to root. For these reasons, the SIR has been set to
Critical.

Cisco has released software updates that address this vulnerability. There are
no workarounds that address this vulnerability.

Fixed Software

Cisco has released free software updates that address the vulnerability
described in this advisory. Customers may only install and expect support for
software versions and feature sets for which they have purchased a license. By
installing, downloading, accessing, or otherwise using such software upgrades,
customers agree to follow the terms of the Cisco software license:
https://www.cisco.com/c/en/us/products/end-user-license-agreement.html
Additionally, customers may only download software for which they have a valid
license, procured from Cisco directly, or through a Cisco authorized reseller
or partner. In most cases this will be a maintenance upgrade to software that
was previously purchased. Free security software updates do not entitle
customers to a new software license, additional software feature sets, or
major revision upgrades.
When considering software upgrades, customers are advised to regularly consult
the advisories for Cisco products, which are available from the Cisco Security
Advisories and Alerts page, to determine exposure and a complete upgrade
solution.
In all cases, customers should ensure that the devices to be upgraded contain
sufficient memory and confirm that current hardware and software
configurations will continue to be supported properly by the new release. If
the information is not clear, customers are advised to contact the Cisco
Technical Assistance Center (TAC) or their contracted maintenance providers.
Customers Without Service Contracts
Customers who purchase directly from Cisco but do not hold a Cisco service
contract and customers who make purchases through third-party vendors but are
unsuccessful in obtaining fixed software through their point of sale should
obtain upgrades by contacting the Cisco TAC:
https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html
Customers should have the product serial number available and be prepared to
provide the URL of this advisory as evidence of entitlement to a free upgrade.

Releases 12.1 and later.
