A command injection vulnerability was privately reported to VMware. Workarounds are available to address this vulnerability in affected VMware products.

3a. Command Injection Vulnerability in VMware Workspace One Access, Access Connector, Identity Manager, and Identity Manager Connector administrative configurator (CVE-2020-4006)

Description

VMware Workspace One Access, Access Connector, Identity Manager, and Identity Manager Connector contain a Command Injection Vulnerability in the administrative configurator. VMware has evaluated this issue to be of 'Important' severity with a maximum CVSSv3 base score of 7.2.

Known Attack Vectors

A malicious actor with network access to the administrative configurator on port 8443 and a valid password for the configurator admin account can execute commands with unrestricted privileges on the underlying operating system. This account is internal to the impacted products and a password is set at the time of deployment. A malicious actor must possess this password to attempt to exploit CVE-2020-4006. Examples of how this password could be obtained by a malicious actor are documented in T1586 of the MITRE ATT&CK database.
