CVE-2017-6708
CWE-200
Summary
A vulnerability in the symbolic link (symlink) creation functionality of
the AutoVNF tool for the Cisco Ultra Services Framework could allow an
unauthenticated, remote attacker to read sensitive files or execute
malicious code on an affected system.
The vulnerability is due to the absence of validation checks for the input
that is used to create symbolic links. A successful exploit could allow the
attacker to read any sensitive file or execute malicious code on an
affected system.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
This advisory is available at the following link:

Affected Products
Vulnerable Products
This vulnerability affects all releases of the Cisco Ultra Services
Framework 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 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.

CVE-2017-6709
CWE-200
Summary
A vulnerability in the AutoVNF tool for the Cisco Ultra Services Framework
could allow an unauthenticated, remote attacker to access administrative
credentials for Cisco Elastic Services Controller (ESC) and Cisco OpenStack
deployments in an affected system.
The vulnerability exists because the affected software logs administrative
credentials in clear text for Cisco ESC and Cisco OpenStack deployment
purposes. An attacker could exploit this vulnerability by accessing the
AutoVNF URL for the location where the log files are stored and
subsequently accessing the administrative credentials that are stored in
clear text in those log files. A successful exploit could allow the
attacker to access the administrative credentials for Cisco ESC and
Cisco OpenStack deployments in the affected system, which the attacker
could use to conduct additional attacks.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
