VMware Cloud Foundation 4.2.1

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 Workspace ONE Access and Identity Manager, allow the /cfg web app and diagnostic endpoints, on port 8443, to be accessed via port 443 using a custom host header. A malicious actor with network access to port 443 could tamper with host headers to facilitate access to the /cfg web app, in addition a malicious actor could access /cfg diagnostic endpoints without authentication.

VMware Workspace ONE Access and Identity Manager contain a privilege escalation vulnerability. A malicious actor with local access can escalate privileges to 'root'.

VMware Workspace ONE Access and Identity Manager, unintentionally provide a login interface on port 7443. A malicious actor with network access to port 7443 may attempt user enumeration or brute force the login endpoint, which may or may not be practical based on lockout policy configuration and password complexity for the target account.

The vCenter Server contains a denial-of-service vulnerability in the content library service. A malicious actor with network access to port 443 on vCenter Server may exploit this issue to trigger a denial-of-service condition by sending a specially crafted header.

VMware ESXi contains a heap-overflow vulnerability. A malicious local actor with restricted privileges within a sandbox process may exploit this issue to achieve a partial information disclosure.
