CVE-2026-19824

Estado: AplazadaAlta (7.4)—

A weakness has been identified in Tenda W20E 15.11.0.6(1068_1546_841)_CN_TDC. The affected element is the function ipMacBindListStore of the file /goform/addIpMacBind. Executing a manipulation of the argument IPMacBindRule can lead to stack-based buffer overflow. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks.
