Authenticated memory corruption via oversized schedule times
Published Mar 27, 2024 · Updated Aug 27, 2024
Stack-based buffer overflow in Tenda F1203 Firmware 2.0.1.6 allows remote authenticated users to corrupt memory via schedule times. The setSchedWifi handler at /goform/openSchedWifi processes oversized schedStartTime or schedEndTime values without enforcing the destination stack buffer bounds. A low-privileged management session is required; public evidence establishes stack corruption but not exploitation in the wild.
