CVE-2024-44387

Service interruption via formWrlExtraGet buffer overflow

Published Aug 23, 2024 · Updated Aug 23, 2024

Stack-based buffer overflow in Tenda FH1206 1.2.0.8(8155)_EN allows adjacent-network attackers to interrupt router service. Published sources identify formWrlExtraGet as the affected function but do not disclose the request endpoint, input field, or unsafe copy operation. Exploitation requires no authentication or user interaction from an adjacent network, and the documented impact is limited to availability; whether the device hangs, crashes, or reboots is not specified.
