WeGIA Reflected Cross-Site Scripting Vulnerability in editar_socio.php Endpoint

A reflected cross-site scripting vulnerability has been identified in the WeGIA application, specifically within the 'editar_socio.php' endpoint. This issue allows attackers to inject malicious scripts through the 'socio' parameter. The vulnerability arises because the application does not properly validate and sanitize user inputs, enabling the injection of harmful payloads that are executed in the context of the user's browser.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where injected scripts are executed in the context of the victim's browser. This can lead to theft of cookies, execution of malicious code on the user's system, and potential compromise of user accounts or data.

Reproduction

To reproduce this vulnerability, send a GET request to the 'editar_socio.php' endpoint with a payload in the 'socio' parameter that includes a script tag. The injected script will be executed in the context of the user's browser, demonstrating the cross-site scripting vulnerability.

Remediation

Users are advised to upgrade to WeGIA version 3.2.8, where this vulnerability has been patched.
