CVE-2021-45878Network attack vector

Unauthenticated information disclosure and modification via web manager

Published Mar 21, 2022 · Updated Aug 4, 2024

Missing authentication in GARO Wallbox GLB/GTB/GTC firmware through 185 allows remote attackers to view and modify device information. The web manager serves information pages and accepts changes without checking for an authenticated session or enforcing access control. Network access to the device's web manager is sufficient, and the documented impact is limited to unauthorized disclosure and modification of information rather than service interruption.
