Отправить #638671: Portabilis i-Educar 2.10 Cross Site Scripting

Stored Cross-Site Scripting (XSS) in endpoint TabelaArredondamento/edit parameter nome

Summary
A Stored Cross-Site Scripting (XSS) vulnerability was identified in the /module/TabelaArredondamento/edit endpoint of the i-Educar application. This vulnerability allows attackers to inject malicious scripts into the nome parameter. 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: /module/TabelaArredondamento/edit

Parameter: nome

Trigger Page: /module/TabelaArredondamento/index

The application fails to properly validate and sanitize user inputs in the nome parameter. 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
Step by Step:
Access vulnerable endpoint and insert the payload in second field ("Nome"), click on "Salvar" and the trigger page will be activated automatically.
