Overview

Multiple vulnerabilities have been reported in VMware products, which could allow a remote attacker to inject malicious email headers, exploit weak password recovery mechanisms, or enumerate valid usernames on the targeted system.

Target Audience:

Enterprises and large organisations, cloud service providers, and industries with IT environments utilising VMware products.

Risk Assessment:

High risk of credential exposure, username enumeration, and manipulation of notification emails.

Impact Assessment:

Potential for exposure of valid usernames, brute-force attacks, or manipulation of scheduled task notification emails.

Description

VMware provides virtualisation software solutions that enable organisations to create and manage virtual machines (VMs), allowing multiple operating systems to run on a single physical machine.

These vulnerabilities affect VMware products due to the presence of an SMTP header injection flaw, a weak password recovery mechanism and a username enumeration vulnerability. An attacker with non-administrative privileges on vCenter who has permission to create scheduled tasks could manipulate notification emails sent for scheduled tasks, while separate flaws in VMware NSX could allow attackers to recover weak passwords or enumerate valid usernames on the system.

Successful exploitation of this vulnerability could allow a remote attacker to inject malicious email headers, exploit weak password recovery mechanisms, or enumerate valid usernames on the targeted system.

Solution
