CVE-2025-28030Network attack vector

Memory corruption via unchecked parental-rule times

Published Apr 22, 2025 · Updated Apr 23, 2025

A stack-based buffer overflow in TOTOLINK A810R firmware 4.1.2cu.5182_B20201026 allows remote attackers to corrupt memory via crafted rule times. The setParentalRules function mishandles attacker-controlled startTime and endTime parameters and writes beyond a stack buffer. Successful exploitation requires user interaction; public sources do not specify the required interaction or a demonstrated outcome beyond memory corruption.
