Summary
Cisco Data Center Network Manager REST API Vulnerabilities

Notes

Summary
Multiple vulnerabilities in the REST API endpoint 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. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-dcnm-api-path-TpTApx2p ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-dcnm-api-path-TpTApx2p"]
Vulnerable Products
At the time of publication, these vulnerabilities affected Cisco DCNM releases earlier than Release 11.4(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 this vulnerability.
Details
The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit the other vulnerabilities. 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-2021-1133: Cisco Data Center Network Manager Path Traversal Vulnerability A vulnerability in the REST API of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker with a low-privilege account to conduct a path traversal attack on an affected device. The vulnerability is due to insufficient validation of user-supplied input to the API. An attacker could exploit this vulnerability by sending a crafted request to the API. A successful exploit could allow the attacker to delete arbitrary files on the file system. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvt82606 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvt82606"] CVE-ID: CVE-2021-1133 Security Impact Rating (SIR): Medium CVSS Base Score: 6.5 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H CVE-2021-1255: Cisco Data Center Network Manager Path Traversal Vulnerability A vulnerability in a certain REST API endpoint of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker to perform a path traversal attack on an affected device. The vulnerability is due to insufficient path restriction enforcement. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to overwrite or list arbitrary files on the affected device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvu28383 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvu28383"] CVE-ID: CVE-2021-1255 Security Impact Rating (SIR): Medium CVSS Base Score: 4.6 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N CVE-2021-1135: Cisco DCNM Software Configuration Bypass Vulnerability A vulnerability in a certain REST API endpoint of Cisco Data Center Network Manager could allow an authenticated, remote attacker to bypass security controls and modify default server configuration settings on the affected device. The vulnerability is due to an incorrect comparison in a denylist implementation. An attacker could exploit this vulnerability by sending specially crafted network traffic to the affected software. A successful exploit could allow the attacker to modify server configuration settings on the affected device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvu28385 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvu28385"] CVE-ID: CVE-2021-1135 Security Impact Rating (SIR): Medium CVSS Base Score: 4.3 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
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 11.4(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.
