Authenticated memory corruption via unbounded shareSpeed value
Published Mar 26, 2024 · Updated Aug 12, 2024
Stack-based buffer overflow in Tenda AC7 15.03.06.44 allows remote authenticated users to corrupt stack memory through shareSpeed requests. The fromSetWifiGusetBasic handler processes the attacker-controlled shareSpeed value without a sufficient length bound, allowing it to exceed its destination stack buffer. Low-privileged web-interface access is required, and triggering the overflow corrupts the management process's stack.
