CWE-287

Summary

A vulnerability in the Ultra Automation Service (UAS) of the Cisco Ultra
Services Framework could allow an unauthenticated, remote attacker to gain
unauthorized access to a targeted device.

The vulnerability is due to an insecure default configuration of the Apache
ZooKeeper service used by the affected software. An attacker could exploit
this vulnerability by accessing the affected device through the
orchestrator network. An exploit could allow the attacker to gain access to
ZooKeeper data nodes (znodes) and influence the behavior of the system's
high-availability feature.

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

UAS prior to Releases 5.0.3 and 5.1.

Products Confirmed Not Vulnerable

No other Cisco products are currently known to be affected by this
vulnerability.

Workarounds

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:
http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.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:
http://www.cisco.com/en/US/support/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.

Fixed Releases

This vulnerability was fixed in Cisco Ultra Services Framework UAS Releases
5.0.3 and 5.1.

Exploitation and Public Announcements

The Cisco Product Security Incident Response Team (PSIRT) is not aware of
any public announcements or malicious use of the vulnerability that is
described in this advisory.
