CVE-2023-47307Public exploitNetwork attack vector

Device crash via unbounded ApCliAuthMode parameter

Published Nov 30, 2023 · Updated Aug 2, 2024

Buffer overflow in /apply.cgi in LBT-T300-T310 2.2.2.6 allows remote attackers to crash the device via ApCliAuthMode. The handler accepts an overlong ApCliAuthMode value without enforcing a length limit before the WLAN configuration call chain processes it. Network access to the management interface is required; the published request includes HTTP Basic credentials, and only a device crash is documented.
