Name of the Vulnerable Software and Affected Versions: DualShield version 5.9.8.0821

Description: The issue allows for username enumeration on the login form. When a valid username is entered, it prompts for the password, while an invalid username results in an "unknown username" error message.

Recommendations: For DualShield version 5.9.8.0821, consider modifying the login form to handle valid and invalid usernames in a way that does not disclose whether a username is valid or not, such as returning a generic error message for all invalid login attempts.
