Cisco has released software updates for its Data Center Network Manager (DCNM) product to address several critical and high-severity issues.

Cisco has released software updates that address several critical and high-severity vulnerabilities in it s Data Center Network Manager (DCNM) product.

All the vulnerabilities were reported to Cisco through Trend Micro’s Zero Day Initiative (ZDI) and Accenture’s iDefense service by the security researcher Steven Seeley of Source Incite and Harrison Neal from PatchAdvisor.

Cisco published six advisories for a dozen vulnerabilities, eleven of them were reported by Seeley, three of these issues have been rated as critical and seven as high severity. The issues reported by Neal have been rated as medium severity.

Some of the critical flaws addressed by Cisco in DCNM could be exploited by attackers to bypass authentication and execute arbitrary actions with admin privileges on the vulnerable devices.

“Multiple vulnerabilities in the authentication mechanisms of Cisco Data Center Network Manager (DCNM) could allow an unauthenticated , remote attacker to bypass authentication and execute arbitrary actions with administrative privileges on an affected device.” reads the advisory published by Cisco.

“For more information about these vulnerabilities, see the Details section of this advisory. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.”

The vulnerabilities have been tracked as CVE-2019-15975, CVE-2019-15976 and CVE-2019-15977. The issues affect the REST API endpoint, the SOAP API endpoint and the web-based management interface.

Cisco also addressed two of the high-severity SQL injection flaws that could be exploited by an attacker with administrative privileges to execute arbitrary SQL commands on a vulnerable device.

Three of the high-severity weaknesses could be exploited by an attacker to conduct path traversals, and two other high-severity issues by exploited by an attacker with admin rights to inject arbitrary commands on the underlying operating system.

The good news is that Cisco is not aware of attacks in the wild exploiting these vulnerabilities.
