Authenticated memory corruption via unchecked remark formatting
Published Jul 27, 2024 · Updated Aug 1, 2024
Stack-based buffer overflow in Tenda O3 1.0.0.10(2478) allows remote authenticated users to corrupt process memory via a crafted remark. The fromMacFilterSet function passes attacker-controlled status and remark values to sprintf without bounding the write to its v75 stack array. An authenticated web-management session is required; published evidence demonstrates the overflow trigger but not code execution or a specific crash.
