CVE-2024-28339Public exploit

Unauthenticated device data disclosure via debuginfo.htm

Published Mar 12, 2024 · Updated Aug 28, 2024

Information disclosure in debuginfo.htm in NETGEAR Orbi CBR40, CBK40, and CBK43 firmware 2.5.0.28 allows remote attackers to read device data. The hidden web-management page omits authentication and returns the WAN connection type and product model to any requester. Access requires network reachability to the router interface, and the documented consequence is disclosure of device configuration details.
