Technical description

WeGIA is a web manager for charitable institutions. Prior to 3.8.6, the unauthenticated web/html/socio/sistema/cadastro_cobrancas_geracao.php endpoint accepts form-encoded POST data through extract($_REQUEST) and interpolates codigo, descricao, data_emissao, data_vencimento, data_pagamento, valor, valor_pago, status, link_cobranca, link_boleto, linha_digitavel, and id_socio into a raw INSERT statement. Numeric parameters are unquoted and unvalidated, while string parameters can break out of their single-quoted SQL context. A remote attacker can execute arbitrary SQL to read or modify billing, member, employee, permission, and credential data or to delete database tables. This issue is fixed in version 3.8.6.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
