Summary
Cisco Data Center Network Manager Authorization Bypass Vulnerabilities

Notes

Summary
Multiple vulnerabilities in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker to view, modify, and delete data without proper authorization. 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
At the time of publication, these vulnerabilities affected Cisco DCNM releases earlier than Release 11.5(1). See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information.
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-2021-1270: Cisco DCNM Authorization Bypass Vulnerability A vulnerability in the web-based management interface of Cisco DCNM could allow an authenticated, remote attacker to modify the configuration without proper authorization. This vulnerability is due to a failure to limit access to resources that are intended for users with Administrator privileges. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow a low-privileged attacker to edit the configuration. To exploit this vulnerability, an attacker would need valid nonadministrative credentials. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvv87627 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvv87627"] CVE-ID: CVE-2021-1270 Security Impact Rating (SIR): Medium CVSS Base Score: 7.1 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L CVE-2021-1269: Cisco DCNM Authorization Bypass Vulnerability A vulnerability in the web-based management interface of Cisco DCNM could allow an authenticated, remote attacker to bypass authorization on an affected device and access sensitive information that is related to the device. This vulnerability is due to a failure to limit access to resources that are intended for users with Administrator privileges. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow a low-privileged attacker to list, view, create, edit, and delete specific system configurations in the same manner as a user with Administrator privileges. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvu57868 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvu57868"] CVE-ID: CVE-2021-1269 Security Impact Rating (SIR): Medium CVSS Base Score: 6.3 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
Workarounds
There are no workarounds that address these vulnerabilities.
Fixed Software
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. Fixed Releases At the time of publication, Cisco DCNM releases 11.5(1) and later contained the fix for these vulnerabilities. See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information.
Vulnerability Policy
To learn about Cisco security vulnerability disclosure policies and publications, see the Security Vulnerability Policy ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html"]. This document also contains instructions for obtaining fixed software and receiving security vulnerability information from Cisco.
Exploitation and Public Announcements
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerabilities that are described in this advisory.
