Summary
A command injection vulnerability exists in VMware Workspace One Access, Access Connector, Identity Manager, and Identity Manager Connector, caused by improper neutralization of special elements used in an OS command. An attacker who holds high-privilege credentials on the affected product can inject operating system commands and, because the vulnerability affects the scope beyond the vulnerable component, can impact confidentiality, integrity, and availability, with no user interaction required and exploitation possible over the network.
