Critical Cisco SD-WAN vManage and HyperFlex Vulnerabilities

Speak With A Security Expert Now


On May 5th, Cisco announced three critical vulnerabilities impacting the SD-WAN vManage and HyperFlex HX software. The vulnerabilities are tracked as CVE-2021-1468 (CVSS: 9.8), CVE-2021-1497 (CVSS: 9.8), and CVE-2021-1505 (CVSS: 9.1). CVE-2021-1468 and CVE-2021-1497 are especially concerning as they do not require any prior authentication. Exploitation of these vulnerabilities may result in the creation of new administrator accounts, command injection, authentication bypass, and privilege escalation.

Although exploit code is not publicly available, the severity and impact of these vulnerabilities on products will make these attractive targets for future attacks. Exploitation has not been identified at this time.

eSentire has recently observed highly aggressive threat actor activity attempting to exploit public-facing services. eSentire assesses that threat actors will adopt these vulnerabilities in attacks in the near future.
