Authenticated memory corruption via unbounded sprintf formatting
Published Aug 28, 2024 · Updated Aug 28, 2024
Stack-based buffer overflow in Tenda O6 1.0.0.7(2054) allows remote authenticated users to corrupt memory via a crafted POST request. The fromSafeSetMacFilter function passes attacker-controlled remark, type, and time values to sprintf without bounding the destination v33 array. Low-privileged access to the management endpoint is required; the public proof of concept demonstrates only the oversized request.
