WeGIA Stored Cross-Site Scripting Vulnerability in Personal Information Editing Endpoint

A stored cross-site scripting vulnerability has been identified in the WeGIA application, specifically within the 'dependente_editarInfoPessoal.php' endpoint. This issue allows attackers to inject malicious scripts into the 'nome' and 'SobrenomeForm' parameters. The injected scripts are stored on the server and executed automatically when the affected page is accessed by users, creating a significant security risk. The vulnerability arises from the application's failure to properly validate and sanitize user inputs, enabling the injection of harmful scripts that could be executed in the context of the user's browser, potentially compromising their data and system.

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, potentially leading to session hijacking, credential theft, and other malicious actions as described in the published advisory.

Reproduction

To reproduce this vulnerability, send a POST request to the 'dependente_editarInfoPessoal.php' endpoint with the 'nome' and 'SobrenomeForm' parameters. Include a script payload, such as a simple alert script, in these parameters. Once the payload is injected, it will be executed automatically when the page is accessed by users.

Remediation

Users are advised to upgrade to WeGIA version 3.2.6 or later, where this vulnerability has been addressed.
