Risk Analysis
This vulnerability in VMware Workspace One Access and Identity Manager products allows an attacker with network access and valid administrator credentials to execute commands with full privileges on the underlying operating system. The high severity and confirmed exploitation in the wild make this a critical vulnerability requiring immediate attention.
Active exploitation of this vulnerability has been observed in the wild, and it is listed in CISA's KEV catalog, indicating a high likelihood of successful attacks. The vulnerability is remotely exploitable given network access to the administrative configurator.
Apply the latest security patches or upgrades for VMware Workspace One Access, Access Connector, Identity Manager, and Identity Manager Connector. Ensure strong, unique passwords are used for administrative accounts and restrict network access to the administrative configurator on port 8443.
Technical Analysis
CVE-2020-4006 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2020-4006 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
