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.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.

Potential Mitigations

  • Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
