A vulnerability was found in LabRedesCefetRJ WeGIA 3.4.0. It has been rated as problematic. Affected by this issue is some unknown functionality of the file /html/matPat/adicionar_tipoSaida.php of the component Adicionar tipo. The manipulation of the argument Insira o novo tipo leads to cross site scripting. The attack may 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 a remote authenticated low-privileged attacker to inject arbitrary web script via the 'Insira o novo tipo' parameter in the adicionar_tipoSaida.php page. Successful exploitation requires user interaction and can lead to session hijacking or unauthorized actions on behalf of the victim. Public exploit code exists but no active widespread exploitation has been reported.
Technical ContextAI
WeGIA is a PHP-based web application. The vulnerability is a classic reflected or stored cross-site scripting flaw (CWE-79) caused by insufficient sanitization of user-supplied input in the parameter 'Insira o novo tipo' processed by the file /html/matPat/adicionar_tipoSaida.php. The CPE string cpe:2.3:a:wegia:wegia:3.4.0:*:*:*:*:*:*:* confirms the affected product and exact version.
RemediationAI
No official vendor patch has been released, and the vendor has not responded to disclosures. As a workaround, implement strict input validation and output encoding for the 'Insira o novo tipo' parameter, or temporarily disable the adicionar_tipoSaida.php functionality if feasible. Enforce a strong Content Security Policy (CSP) to limit script execution across the application. These measures mitigate the XSS risk but do not eliminate the underlying flaw.
