Summary

User enumeration is found in PHP Jabbers Time Slots Booking Calendar v3.3. 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. This increases the risk of data breaches and security violations.

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.
