Portabilis i-Educar 2.8.0 is vulnerable to SQL Injection in the "getDocuments" function of the "InstituicaoDocumentacaoController" class. The "instituicao_id" parameter in "/module/Api/InstituicaoDocumentacao?oper=get&resource=getDocuments&instituicao_id" is not properly sanitized, allowing an unauthenticated remote attacker to inject malicious SQL commands.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
