VMware NSX contains a weak password recovery mechanism vulnerability. An unauthenticated malicious actor may exploit this to enumerate valid usernames, potentially enabling brute-force attacks.

Impact: Username enumeration → credential brute force risk. Attack Vector: Remote, unauthenticated. Severity: Important. CVSSv3: 8.1 (High).

Acknowledgments: Reported by the National Security Agency.

Affected Products:VMware NSX 9.x.x.x, 4.2.x, 4.1.x, 4.0.x

NSX-T 3.x VMware Cloud Foundation (with NSX) 5.x, 4.5.x

Fixed Versions: NSX 9.0.1.0; 4.2.2.2/4.2.3.1 http://4.2.2.2/4.2.3.1 ; 4.1.2.7; NSX-T 3.2.4.3; CCF async patch (KB88287). Workarounds: None.

Description: VMware NSX contains a username enumeration vulnerability. An unauthenticated malicious actor may exploit this to enumerate valid usernames, potentially leading to unauthorized access attempts.

Impact: Username enumeration → facilitates unauthorized access.

Attack Vector: Remote, unauthenticated.

Workarounds: None.

VMware NSX contains a stored Cross-Site Scripting (XSS) vulnerability in the gateway firewall due to improper input validation.

VMware NSX contains a command injection vulnerability.

A malicious actor with access to the NSX Edge CLI terminal may be able to craft malicious payloads to execute arbitrary commands on the operating system as root.

VMware NSX contains a stored Cross-Site Scripting (XSS) vulnerability in the router port due to improper input validation.

VMware NSX 6.0 before 6.0.6, and vCloud Networking and Security (vCNS) 5.1 before 5.1.4.2 and 5.5 before 5.5.3, does not properly validate input, which allows attackers to obtain sensitive information via unspecified vectors.
