VMware has addressed a critical vulnerability that affects multiple products that could be exploited to gain access to confidential information.

VMware has released security updates to address multiple flaws in its products, including a critical issue that could allow an attacker to access confidential information.

A couple of vulnerabilities tracked as CVE-2021-22002 and CVE-2021-22003, impact Workspace One Access (Access), Identity Manager (vIDM), vRealize Automation (vRA), Cloud Foundation, and vRealize Suite Lifecycle Manager.

VMware has evaluated this issue to be of ‘Important‘ severity with a maximum CVSSv3 base score of 8.6.” states the report. reads the security advisory published by the company.

The CVE-2021-22003 flaw is an Information Disclosure Vulnerability that resides in the VMware Workspace One Access and Identity Management.

Both solutions unintentionally provide a login interface on port 7443, an attacker could exploit the issue to enumerate the users or conduct brute force attack on the endpoint. 

“VMware Workspace One Access and Identity Manager, unintentionally provide a login interface on port 7443. VMware has evaluated this issue to be of ‘Low‘ severity with a maximum CVSSv3 base score of 3.7.” states the advisory. “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.”“
