Submit #629164: Portabilis i-Educar 2.10 Cross Site Scripting

Summary

The application fails to properly validate and sanatize user supplied input, hence leading to a stored cross-site scripting vulnerability that resides within the neighborhood input field (campo para inserção do bairro) on `/intranet/educar_instituicao_cad.php `

Details

While editing the neighborhood input field, which can be accessed at _Cadastro> Instiuição> Editar_, it's possible to insert arbitrary javascript code which is then stored and executed once the user gets back to the previous page.

PoC

Firstly, the neighborhood field was changed and the payload `"><svg onload=alert(1)>` was inserted.
