Code execution via oversized SSID input
Published Aug 5, 2024 · Updated Aug 5, 2024
Buffer overflow in TOTOLINK N350RT 9.3.5u.6139_B20201216 allows remote authenticated users to execute arbitrary code. The setWizardCfg function in /cgi-bin/cstecgi.cgi accepts an attacker-controlled ssid value without checking that it fits the destination buffer. Access to the network management interface and low privileges are required; an oversized value can crash the router or execute code on it.
