Description

RosarioSIS versions before 12.9 fail to validate the filename request parameter in Users and Students modules, allowing authenticated users to unlink allow-listed files via path traversal. Attackers can use parent-directory sequences to escape upload directories and delete CSS, XML, JSON resources and other users' documents throughout the installation.
