Halo Surface Signal score for CVE-2020-4006

The affected products, including VMware Workspace One Access and Identity Manager, are enterprise identity and access management solutions. These are commonly deployed as internet-facing or edge-accessible gateways to facilitate remote authentication and portal access for users, which frequently results in the management interfaces being exposed to the network.

Horizon Alert

Summary of the vulnerability and why it matters

VMware Workspace One Access, Access Connector, Identity Manager, and Identity Manager Connector are susceptible to a command injection vulnerability. This flaw allows an attacker with administrative access to the configurator to execute commands with unrestricted privileges on the underlying operating system. The potential impact includes unauthorized system control and data compromise.

  • Vulnerable VMware management interfaces.
  • Unrestricted command execution capability.
  • Compromise of underlying operating systems.

Attack Path

How an attacker could exploit the issue

This vulnerability allows an attacker to execute commands on the underlying operating system. The attack requires an attacker to first gain access to the administrative configurator interface, which is accessible over the network. Once authenticated, the attacker can exploit the vulnerability to achieve control over the system.

  • Network access to administrative configurator.
  • Authenticated access to administrative interface.
  • Execute commands, gain system control.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability presents a significant threat due to its potential for widespread impact. Attackers with administrative credentials could gain complete control over affected systems, leading to data compromise and disruption of critical business operations. The complexity of exploitation is low, making it accessible to a broad range of malicious actors.

  • Likely attacker skill level: Moderate.
  • Required access or conditions: Administrative credentials.
  • Business risk or urgency: High.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

VMware Workspace One Access, Access Connector, Identity Manager, and Identity Manager Connector have a command injection vulnerability that could allow an attacker to execute commands with unrestricted privileges on the operating system. This could impact system integrity and lead to unauthorized access to sensitive data. The business risk associated with this vulnerability is significant due to the potential for full system compromise.

  • Identify all instances of affected VMware products.
  • Restrict network access to administrative interfaces.
  • Apply vendor updates, verify, and monitor.

Frequently asked questions

What is VMware Workspace One Access and Identity Manager?

VMware Workspace One Access and Identity Manager are enterprise software solutions used for managing user identities and controlling access to applications. They act as a central point for authentication, enabling users to securely access various resources, often remotely, through a unified portal.

What type of vulnerability is CVE-2020-4006?

CVE-2020-4006 is a command injection vulnerability (CWE-78). This means an attacker can trick the software into executing arbitrary operating system commands, potentially gaining unrestricted privileges on the affected system.

What conditions are needed for an attacker to exploit CVE-2020-4006?

An attacker must first have network access to the administrative configurator interface of the affected VMware product. Additionally, the attacker needs valid administrative credentials for that configurator to exploit the vulnerability. Exploitation does not occur if the attacker lacks network access or proper authentication.

Who should be concerned about this external-facing vulnerability?

Organizations using VMware Workspace One Access, Access Connector, Identity Manager, or Identity Manager Connector should be concerned. Since these products are often internet-facing or accessible from the network to manage user access, this vulnerability poses a risk to external and edge-accessible systems.

What is the first step to address this threat?

The immediate first step is to identify all installations of the affected VMware products within your environment. Following that, it's crucial to apply the updates provided by VMware to remediate the vulnerability and restrict network access to administrative interfaces as a precautionary measure.
