Technical details

Insufficient sanitization and encoding of the "Nombre" field in the '/PlantillasMail/Edit' endpoint allows attackers to store JavaScript code that executes in victims' browsers. Exploitation requires authenticated access to the mail template functionality; the injected code runs with the privileges of users viewing the affected templates, allowing session hijacking or malicious actions. A fix is available in ALO Suite version 26_04_15.03_10.
