Name of the Vulnerable Software and Affected Versions PHPJabbers Appointment Scheduler version 3.0

Description The issue is related to user enumeration, which occurs during the password recovery process. A difference in messages could allow an attacker to determine if a user is valid or not, enabling a brute force attack with valid users.

Recommendations For PHPJabbers Appointment Scheduler version 3.0, consider modifying the password recovery process to return generic messages for all users, regardless of their validity, to prevent user enumeration. As a temporary workaround, restrict access to the password recovery feature to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
