WeGIA Stored Cross-Site Scripting Vulnerability in remuneration.php

A stored cross-site scripting vulnerability has been identified in the WeGIA application, specifically within the 'remuneracao.php' endpoint. This issue allows attackers to inject malicious scripts into the 'descricao' 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 the application's failure to properly validate and sanitize user inputs, enabling the injection of harmful scripts that could compromise user data and systems.

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 browser-based attacks.

Reproduction

To reproduce this vulnerability, send a POST request to the 'html/funcionario/remuneracao.php' endpoint with a 'descricao' parameter containing a script payload, such as a JavaScript alert. The injected script will be executed when the page is accessed, demonstrating the cross-site scripting vulnerability.

Remediation

Users are advised to upgrade to WeGIA version 3.2.6 or later.
