CVE-2021-1142: Cisco Security Advisory: Cisco Smart Software Manager Satellite Web UI Command Injection Vulnerabilities

The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit another vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerabilities.

Details about the vulnerabilities are as follows:

CVE-2021-1138, CVE-2021-1140, CVE-2021-1142: Cisco Smart Software Manager Satellite I Command Injection Vulnerabilities

Vulnerabilities in the web UI of Cisco Smart Software Manager Satellite could allow an unauthenticated, remote attacker to execute arbitrary commands as a high-privileged user on an affected device.

These vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by sending malicious HTTP requests to an affected device. A successful exploit could allow the attacker to run arbitrary commands on the underlying operating system.

Cisco has released free software updates that address the vulnerabilities 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 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 these vulnerabilities in Cisco Smart Software Manager On-Prem releases 6.3.0 and later.

Note: With Release 6.3.0, Cisco Smart Software Manager Satellite was renamed to Cisco Smart Software Manager On-Prem.
