Description
From the self-management functionality for the registration of an employee, it is possible to change the information of other employees from other companies. An attacker can initiate a request to confirm the registration of an employee and change the DNI to different values so that it replaces the existing data. In this way the information sent will be stored in the company, updating all the information of the targeted employees such as names, e-mail addresses, dates of birth, addresses, telephone numbers, among others.
Impact
Modify or replace the information of other employees independently of the company.
Recommendation
Verify that the user who is trying to modify the information has the necessary permissions to access.
