Portabilis i-Educar Cross-Site Scripting Vulnerability in Version 2.10

A stored cross-site scripting vulnerability has been identified in Portabilis i-Educar version 2.10. The issue resides in the '/intranet/empresas_cad.php' file, where the 'fantasia' and 'razao_social' parameters can be manipulated to inject malicious scripts. These scripts are stored on the server and executed automatically when the page is accessed, posing a significant security risk. The vulnerability can be exploited remotely and requires user interaction.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user accessing the page. This can lead to session hijacking, downloading of malware, browser exploitation, credential theft, access to sensitive information, website defacement, and reputational damage to businesses.

Reproduction

To reproduce this vulnerability, access the '/intranet/empresas_cad.php' endpoint. Insert a payload, such as an image tag with an 'onerror' event, into the 'fantasia' and 'razao_social' fields. After saving, the payload will be executed automatically when the '/intranet/empresas_lst.php' page is accessed.
