WeGIA Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in the WeGIA application, specifically within the 'modulos_visiveis.php' endpoint. This issue allows attackers to inject malicious scripts through the 'msg_c' parameter. The vulnerability arises from inadequate validation and sanitization of user inputs, enabling the injection of harmful payloads that are executed in the context of the user's browser. This vulnerability affects WeGIA versions prior to 3.2.7 and has been patched in version 3.2.8.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where injected scripts are executed in the context of the user's browser. This can lead to various consequences, such as stealing cookies, executing malicious code on the user's system, compromising accounts, and damaging business reputation.

Reproduction

To reproduce this vulnerability, send a GET request to the 'modulos_visiveis.php' endpoint with a 'msg_c' parameter containing a script tag, such as '<script>alert(1)</script>'. The injected script will be executed in the context of the user's browser.

Remediation

Users are advised to update to WeGIA version 3.2.8 or later.
