Improper Authorization in Export role function in limesurvey/limesurvey


Reported on

Jun 28th 2023


The application controls user rights incorrectly, leading to the attacker being able to collect sensitive information.

Proof of Concept

Step1: The administrator user accesses the user role management function and performs the 'export role' operation.


Step2: Upon observation, a HTTP request GET /index.php?r=userRole/runExport&ptid=121 is seen performing the export task. Any user can directly accesses the path, and successfully downloads the exported role file.



The attacker only needs to change the ID arbitrarily to be able to download information about any user role.
