Quote/0 firmware upgrade endpoint authorization validation flaw

RSS

Release Date: August 29, 2025
Last Updated: August 29, 2025
Severity: High Status: Fixed
CVSS 4.0 Score: 8.7 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N)

Overview

We received a security report about the Quote/0 device update endpoint on 2025-08-26T16:02:00Z. The flaw could lead to unauthorized access to sensitive device-related information. We completed the fix and deployment on 2025-08-26T18:00:00Z, and there is currently no evidence of malicious exploitation.

Impact Scope

ItemDetails
Affected ProductQuote/0 device update page
Affected VersionsNone
Fixed VersionNone
Affected ComponentFirmware upgrade API endpoint (/api/device/firmware)
Attack VectorNetwork
Required PrivilegesNo authentication required

Technical Details

The firmware upgrade endpoint lacked sufficient authorization checks when processing device serial number queries. By crafting specific requests, an attacker could obtain complete device information without authentication, including but not limited to:

  • Device configuration metadata
  • Certain user-associated information

Note: This vulnerability requires network access. It does not impact core device functionality, and we have not observed signs of automated bulk data extraction.

Remediation

We implemented the following security improvements:

Immediate Fixes

  • Applied data minimization by strictly limiting returned fields

Long-term Enhancements

  • Conducted a comprehensive audit of authorization models across all API endpoints |

Impact Assessment

Based on detailed log analysis and forensic investigation:

  • No evidence of malicious exploitation: no abnormal bulk requests or data extraction
  • Impact is contained: only affects single API responses; no persistence risk
  • User data integrity: core user data and business logic remain unaffected

Acknowledgments

We sincerely thank Misaka for reporting this issue through responsible disclosure and providing valuable verification assistance during the fix. This spirit of collaboration helps protect all users' data security.

Disclaimer: This advisory is compiled based on currently available information. We will continue to monitor relevant threat intelligence and update this advisory if there are significant changes.
