Dear Xiaomi Security Team,
I have identified a *critical security vulnerability* in one of your APIs related to device critical data signing. The issue is present at the following endpoint:
*Vulnerable API URL:* https://protect.dev.sec.intl.miui.com/factory/encrypt/deviceInfo
### *Issue Description:*
The API allows *unauthenticated* users to generate *CSSD (Cryptographic Signed Security Data) and critical_data* using only the *sid and secretKey* parameters. This means:
- No *username/password authentication* is required.
- An attacker can *generate unlimited signed critical data* without authorization.
- This could lead to potential abuse, including device authentication bypass, unauthorized device registration, or data manipulation.
### *Impact:*
This vulnerability could enable attackers to:
*Bypass device security mechanisms*
*Exploit Xiaomi’s authentication systems*
*Potentially manipulate device data for unauthorized access*
### *Steps to Reproduce:*
1. Send a request to https://protect.dev.sec.intl.miui.com/factory/encrypt/deviceInfo
2. Provide only the sid and secretKey parameters
3. Observe that the API successfully generates *CSSD and critical_data* without requiring authentication
### *Suggested Fix:*
- Implement *strong authentication* for this API (e.g., token-based access).
- Restrict *unauthorized access* to ensure that only validated Xiaomi services can generate signed data.
### *Disclosure Policy:*
I am *sharing this information responsibly* and have not disclosed it publicly. Please review this issue as soon as possible, as it poses a significant security risk.
I would appreciate a response regarding the remediation plan and any further information needed.
*Best regards,*
