In DayByDay CRM, version 2.2.0 is vulnerable to missing authorization. Any application user in the application who has update user permission enabled is able to change the password of other users, including the administrator’s. This allows the attacker to gain access to the highest privileged user in the application.

In Daybyday CRM, versions 1.1 through 2.2.0 enforce weak password requirements in the user update functionality. A user with privileges to update his password could change it to a weak password, such as those with a length of a single character. This may allow an attacker to brute-force users’ passwords with minimal to no computational effort.

In Daybyday CRM, version 2.2.0 is vulnerable to Stored Cross-Site Scripting (XSS) vulnerability that allows low privileged application users to store malicious scripts in the title field of new tasks. These scripts are executed in a victim’s browser when they open the “/tasks” page to view all the tasks.

In Daybyday CRM, versions 2.0.0 through 2.2.0 are vulnerable to Missing Authorization. An attacker that has the lowest privileges account (employee type user), can view the absences of all users in the system including administrators. This type of user is not authorized to view this kind of information.

In Daybyday CRM, versions 2.0.0 through 2.2.0 are vulnerable to Missing Authorization. An attacker that has the lowest privileges account (employee type user), can view the appointments of all users in the system including administrators. However, this type of user is not authorized to view the calendar at all.
