VMware Ships Urgent Patch for Authentication Bypass Security Hole

Virtualization technology giant VMware on Tuesday shipped an urgent, high-priority patch to address an authentication bypass vulnerability in its Workspace ONE Access, Identity Manager and vRealize Automation products.

The vulnerability carries VMware’s highest severity rating (CVSSv3 base score of 9.8) and should be remediated without delay, the company said in an advisory.

"VMware Workspace ONE Access, Identity Manager and vRealize Automation contain an authentication bypass vulnerability affecting local domain users. A malicious actor with network access to the UI may be able to obtain administrative access without the need to authenticate," VMware warned.

“This critical vulnerability should be patched or mitigated immediately per the instructions in [the advisory],” VMware said.

The latest patches also include cover for at least 9 documented vulnerabilities affecting the VMware Workspace ONE Access, Access Connector, Identity Manager, Identity Manager Connector and vRealize Automation product lines.
