WeGIA Stored Cross-Site Scripting Vulnerability in CobrancaController.php

A stored cross-site scripting vulnerability has been identified in the WeGIA application, specifically within the CobrancaController.php endpoint. This issue allows attackers to inject malicious scripts into the local_recepcao parameter, which are then stored on the server. The injected scripts are executed automatically when the affected page is accessed by users, creating a significant security risk. The vulnerability arises from inadequate validation and sanitization of user inputs in the local_recepcao parameter, enabling the injection of harmful scripts that could be executed in the context of the user's browser.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user accessing the affected page. This could lead to session hijacking, credential theft, and the execution of malicious actions on behalf of the user.

Reproduction

To reproduce this vulnerability, send a POST request to the /html/socio/sistema/controller/CobrancaController.php endpoint with a local_recepcao parameter containing the injected script. The application will store the script on the server, and it will be executed automatically when the page is accessed by users.

Remediation

Users can update to WeGIA version 3.2.8, where this vulnerability has been fixed.
