Cisco Smart Software Manager On-Prem Static Default Credential Vulnerability
Priority: Critical
Advisory ID: cisco-sa-on-prem-static-cred-sL8rDs8
First Published: 2020 February 19 16:00 GMT
Version 1.0: Final

CVE-2020-3158
CWE-798
CVSS Score:

Summary
o A vulnerability in the High Availability (HA) service of Cisco Smart
Software Manager On-Prem could allow an unauthenticated, remote attacker to
access a sensitive part of the system with a high-privileged account.
The vulnerability is due to a system account that has a default and static
password and is not under the control of the system administrator. An
attacker could exploit this vulnerability by using this default account to
connect to the affected system. A successful exploit could allow the
attacker to obtain read and write access to system data, including the
configuration of an affected device. The attacker would gain access to a
sensitive portion of the system, but the attacker would not have full
administrative rights to control the device.
Cisco has released software updates that address the vulnerability
described in this advisory. There are no workarounds that address this
vulnerability.

Affected Products
o Vulnerable Products
This vulnerability affects Cisco Smart Software Manager On-Prem releases
earlier than 7-202001 if the High Availability (HA) feature is enabled. HA
is not enabled by default.
Determine Whether High Availability Is Enabled
The HA feature must be enabled for Cisco Smart Software Manager On-Prem to
be affected by the vulnerability described in this advisory. To determine
whether the HA feature is configured on a device, administrators can log in
to the administrative web interface and look for the presence of the High
Availability Status widget in the main dashboard. If the widget exists, HA
is enabled. Administrators can also SSH to the system, enter onprem-console
at the prompt, and issue the ha_status command at the CLI.
The following example shows the CLI output when HA is enabled:
[admin@SSM-On-Prem ~]$ onprem-console
SSM On-Prem Console
>> ha_status

Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
Details
o Cisco Smart Software Manager satellite and Cisco Smart Software Manager
On-Prem are the same product. Prior to Release 7.0, this product was named
Cisco Smart Software Manager satellite. As of Release 7.0, this product has
been named Cisco Smart Software Manager On-Prem (SSM On-Prem).
Workarounds
o There are no workarounds that address this vulnerability.
Fixed Software
o 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.
Fixed Releases
Cisco fixed this vulnerability in Cisco Smart Software Manager On-Prem
releases 7-202001 and later.
