Portabilis i-Educar 2.8.0 is vulnerable to SQL Injection in the "getDocuments" function of the "InstituicaoDocumentacaoController" class. The "instituicaoid" parameter in "/module/Api/InstituicaoDocumentacao?oper=get&resource=getDocuments&instituicaoid" is not properly sanitized, allowing an unauthenticated remote attacker to inject malicious SQL commands.
