Analysis Summary
The vulnerability is tracked as CVE-2020-4006 and it has been found to impact the VMware Workspace ONE Access identity management product and some related components, including Identity Manager (vIDM) on Linux, vIDM Connector on Windows and Linux, VMware Cloud Foundation and vRealize Suite Lifecycle Manager. An attacker who has gained access to the system’s web-based management interface can exploit the vulnerability to execute arbitrary commands with elevated privileges on the underlying operating system.
It has recently been reported that Russian state-sponsored malicious cyber actors have been exploiting CVE-2020-4006. Information about the targets of this attack has not been released. Based on the disclosure timeline, it’s likely that the security hole was being exploited before a patch was released. The exploitation via command injection led to installation of a web shell and follow-on malicious activity where credentials in the form of SAML authentication assertions were generated and sent to Microsoft Active Directory Federation Services (ADFS), which in turn granted the actors access to protected data.
