Critical Flaws Hit Cisco SD-WAN vManage and HyperFlex Software

May 6, 2021

Networking gear main Cisco has rolled out software program updates to handle a number of crucial vulnerabilities impacting HyperFlex HX and SD-WAN vManage Software program that might permit an attacker to carry out command injection assaults, execute arbitrary code, and acquire entry to delicate data.

In a collection of advisories revealed on Might 5, the corporate stated there are not any workarounds that remediate the problems.

The HyperFlex HX command injection vulnerabilities, tracked as CVE-2021-1497 and CVE-2021-1498 (CVSS scores 9.8), have an effect on all Cisco gadgets operating HyperFlex HX software program variations 4.0, 4.5, and people previous to 4.0. Arising attributable to inadequate validation of user-supplied enter within the web-based administration interface of Cisco HyperFlex HX Knowledge Platform, the issues might allow an unauthenticated, distant attacker to carry out a command injection assault towards a susceptible system.

The distant code execution flaw (CVE-2021-21984, CVSS rating: 9.8) stems from an unauthorized VAMI endpoint, leading to a state of affairs that might trigger an adversary with community entry to run unauthorized code on the equipment. Affected clients can rectify the problem by installing the safety patch ISO file.

Vmware credited Egor Dimitrenko of Constructive Applied sciences for reporting the vulnerability.
