In February 2021, we had the opportunity to assess the HyperFlex HX platform from Cisco during a routine customer engagement. This resulted in the detection of three significant vulnerabilities. In this article we discuss our findings and will explain why they exist in the platform, how they can be exploited and the significance of these vulnerabilities.
The vulnerabilities discussed have been assigned CVE ID’s and considered in Cisco’s subsequent Security Advisories (1, 2). These are:
