Summary
User enumeration is found in PHP Jabbers Restaurant Booking Script v3.0. This issue occurs during password recovery, where a difference in messages could allow an attacker to determine if the user is valid or not, enabling a brute force attack with valid users.
Risk Assessment
The organization may be exposed to brute force attacks, potentially leading to unauthorized access to user accounts. Allowing attackers to identify valid users increases the risk of security breaches.
Recommendation
It is recommended to implement uniform messages during the password recovery process to minimize the risk of user enumeration. Additionally, consider implementing further security measures, such as limiting the number of login attempts.
