Neutralização inadequada de caracteres especiais em lógica de consulta de dados

Ocorre quando a aplicação não sanitiza adequadamente dados do usuário antes de usá-los em consultas (SQL, LDAP, XPath, etc.), permitindo que caracteres ou sequências especiais sejam interpretados como parte da sintaxe da consulta. Um atacante injeta comandos ou operadores que modificam a lógica esperada, contornando filtros de autenticação ou acessando dados não autorizados.

Exemplo

Um login que concatena diretamente a entrada do usuário em uma query LDAP: filter = '(uid=' + username + ')'. Se o atacante digitar 'admin*', a busca retorna qualquer usuário com uid começando em 'admin', contornando validação de senha. Ou em SQL, inserir aspas e operadores booleanos para alterar o WHERE da consulta.

Como mitigar

Use prepared statements ou consultas parametrizadas (placeholders) em vez de concatenação de strings. Para LDAP e XPath, aplique escape de caracteres especiais conforme o padrão da tecnologia. Valide e restrinja entrada do usuário a um whitelist de valores esperados sempre que possível.
