A vulnerability was found in LabRedesCefetRJ WeGIA 3.4.0. It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the file /html/matPat/adicionar_tipoEntrada.php of the component Adicionar tipo. The manipulation of the argument Insira o novo tipo leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Cross-site scripting in WeGIA 3.4.0 allows remote attackers to inject arbitrary web script via the 'Insira o novo tipo' parameter in /html/matPat/adicionar_tipoEntrada.php. The vulnerability requires an authenticated user to click a malicious link, but exploit code is publicly available. No active exploitation has been confirmed.
Technical ContextAI
The flaw is in the PHP-based WeGIA application's 'Adicionar tipo' component. The script adicionar_tipoEntrada.php fails to sanitize user input to the 'Insira o novo tipo' parameter before reflecting it in the response, leading to reflected cross-site scripting (CWE-79). This allows script injection that executes in the victim's browser context.
RemediationAI
No vendor patch is available. Mitigations include disabling the vulnerable script if not needed, implementing server-side input validation to escape HTML characters in the affected parameter, or deploying a WAF rule to block XSS payloads. Each mitigation carries trade-offs: disabling may break functionality, custom validation requires development resources, and a WAF may miss obfuscated attacks. Monitor the vendor advisory for an official fix.
