Description
Description
WeGIA is a web manager for charitable institutions. Prior to the advisory's stated patched version 3.8.7, the `/controle/control.php` dispatch endpoint accepts attacker-controlled `nomeClasse`, `metodo`, and record identifier parameters through `extract($_REQUEST)`, including id, `idatendido`, `idInterno`, and `id_funcionario`, while the affected Controle CRUD methods do not verify record ownership. Any authenticated user can view, modify, or delete another user's records, exposing CPF, RG, addresses, medical records, financial data, and employee records. `AtendidoControle` lacks ownership checks on alterar, excluir, `listarUm`, `alterarInfPessoal`, `alterarDocumentacao`, `alterarImagem`, `alterarEndereco`, and `alterarStatus`; `InternoControle` lacks them on incluir, alterar, excluir, `listarUm`, `listarTodos`, and `listarCpf`. `FuncionarioControle` lacks ownership checks on `alterarInfPessoal`, `alterarEndereco`, `alterarDocumentacao`, `alterarImagem`, `alterarCargaHoraria`, and excluir; `VoluntarioControle` lacks them on `alterarInfPessoal`, `alterarEndereco`, `alterarDetalhes`, `alterarImagem`, and excluir. `AtendidoControle` and `InternoControle` additionally lack CSRF validation, allowing a malicious page visited by an authenticated victim to perform state-changing operations using the victim's session. `FuncionarioControle` and `VoluntarioControle` have per-method CSRF checks, but those checks do not prevent the object-authorization bypass. The advisory identifies version 3.8.7 as patched.
