Отправить #625794: Portabilis i-diario 1.5.0 Cross Site Scripting (XSS) Stored

Cross-Site Scripting (XSS) Stored endpoint '/registros-de-conteudos-por-areas-de-conhecimento/[ID]' in multiples parameters

### Summary

A Stored Cross-Site Scripting (XSS) vulnerability was identified in the `/registros-de-conteudos-por-areas-de-conhecimento/[ID]` endpoint of the i-diario application. This vulnerability allows attackers to inject malicious scripts into `multiples parameters`. The injected scripts are stored on the server and executed automatically whenever the affected page is accessed by users, posing a significant security risk.

### Details

Vulnerable Endpoint: `//registros-de-conteudos-por-areas-de-conhecimento/[ID] `
Parameter: `Registro de atividades, Conteúdos`

The application fails to properly validate and sanitize user inputs in the `Registro de atividades, Conteúdos` parameters. This lack of validation allows attackers to inject malicious scripts, which are then stored on the server. Whenever the affected page is accessed, the malicious payload is executed in the victim's browser, potentially compromising the user's data and system.

### PoC

Payload: `<script>alert('PoC-XXS2')</script>`

1 - Insert the payload in the Parecer parameter.
2 - Save it
3 - Go to the option "Histórico"
