Service interruption via security_5g stack overflow
Published Mar 28, 2024 · Updated Aug 16, 2024
Stack overflow in Tenda FH1202 firmware 1.2.0.14(408) allows remote attackers to interrupt service from an adjacent network. The formWifiBasicSet handler overflows a stack buffer while processing an oversized security_5g parameter; the specific copy operation is undisclosed. No authentication or user interaction is required, but the attacker must reach the router from an adjacent network; the documented consequence is service interruption.
