Summary
Cisco Redundancy Configuration Manager for Cisco StarOS Software Multiple Vulnerabilities
Notes
Summary
Multiple vulnerabilities in Cisco Redundancy Configuration Manager (RCM) for Cisco StarOS Software could allow a unauthenticated, remote attacker to disclose sensitive information or execute arbitrary commands as the root user in the context of the configured container.
For more information about these vulnerabilities, see the Details ["#details"] section of this advisory.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
Vulnerable Products
These vulnerabilities affect Cisco RCM for Cisco StarOS Software.
For information about which Cisco software releases are vulnerable, see the Fixed Software ["#fs"] section of this advisory.
For additional information about this product, see Redundancy Configuration Manager - Configuration and Administration Guide, Release 2021.01 ["https://www.cisco.com/c/dam/en/us/td/docs/wireless/ucc/upf/2021-01/RCM/ucc-5g-rcm-config-and-admin-guide_2021-01.pdf"].
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by these vulnerabilities.
Details
The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit the other vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerability.
Details about the vulnerabilities are as follows:
CVE-2022-20649: Cisco RCM Debug Remote Code Execution Vulnerability
A vulnerability in Cisco RCM for Cisco StarOS Software could allow an unauthenticated, remote attacker to perform remote code execution on the application with root-level privileges in the context of the configured container.
This vulnerability exists because the debug mode is incorrectly enabled for specific services. An attacker could exploit this vulnerability by connecting to the device and navigating to the service with debug mode enabled. A successful exploit could allow the attacker to execute arbitrary commands as the root user.
The attacker would need to perform detailed reconnaissance to allow for unauthenticated access. The vulnerability can also be exploited by an authenticated attacker.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCvy80878 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvy80878"]
CVE IDs: CVE-2022-20649
Security Impact Rating (SIR): Critical
CVSS Base Score: 9.0
CVSS Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H
CVE-2022-20648: Cisco RCM Debug Information Disclosure Vulnerability
A vulnerability in a debug function for Cisco RCM for Cisco StarOS Software could allow an unauthenticated, remote attacker to perform debug actions that could result in the disclosure of confidential information that should be restricted.
This vulnerability exists because of a debug service that incorrectly listens to and accepts incoming connections. An attacker could exploit this vulnerability by connecting to the debug port and executing debug commands. A successful exploit could allow the attacker to view sensitive debugging information.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Bug ID(s): CSCvy80857 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvy80857"]
CVE IDs: CVE-2022-20648
Security Impact Rating (SIR): Medium
CVSS Base Score: 5.3
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Workarounds
There are no workarounds that address these vulnerabilities.
Fixed Software
Cisco has released free software updates ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#ssu"] that address the vulnerabilities described in this advisory. Customers with service contracts that entitle them to regular software updates should obtain security fixes through their usual update channels.
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 ["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.
The Cisco Support and Downloads page ["https://www.cisco.com/c/en/us/support/index.html"] on Cisco.com provides information about licensing and downloads. This page can also display customer device support coverage for customers who use the My Devices tool.
When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page ["https://www.cisco.com/go/psirt"], 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 ["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
In the following table(s), the left column lists Cisco software releases. The right column indicates whether a release is affected by the vulnerabilities described in this advisory and the first release that includes the fix for these vulnerabilities. Customers are advised to upgrade to an appropriate fixed software release ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"] as indicated in this section.
Cisco RCM for StarOS Release First Fixed Release Earlier than 21.25 Migrate to a fixed release. 21.25 21.25.4
To download the software from the Software Center ["https://software.cisco.com/download/home"] on Cisco.com, do the following:
Click Browse all.
Choose Wireless > Mobile Internet > Platforms > Ultra Packet Core > Ultra Software.
Choose a release from the left pane.
The Cisco Product Security Incident Response Team (PSIRT) validates only the affected and fixed release information that is documented in this advisory.
