A vulnerability has been found in Tenda F456 1.0.0.5. This issue affects the function fromNatStaticSetting of the file /goform/NatStaticSetting. The manipulation of the argument page leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.
AnalysisAI
Stack-based buffer overflow in Tenda F456 router firmware v1.0.0.5 allows authenticated remote attackers to achieve code execution with high integrity and availability impact via crafted 'page' parameter to the /goform/NatStaticSetting endpoint's fromNatStaticSetting function. Public exploit code exists (EPSS 0.05%, 14th percentile), indicating low observed exploitation probability despite proof-of-concept availability. …
