Risks

The attacks that a malicious actor can conduct by exploiting any of these three vulnerabilities are of low complexity and don’t require user interaction.

An attacker with network access to Workspace ONE Assist can obtain administrative access without having to authenticate to the application.

Recommended Actions

The Centre for Cyber Security Belgium recommends that administrators of VMware systems check if their devices are affected according to the respective security advisories.

Since an update is available (Workspace ONE Assist 22.10 (89993)), we urge administrators to prioritize patching these devices as soon as possible.
