CVE-2023-46424Public exploit

Unauthenticated command execution via undisclosed sub_422BD4 input

Published Oct 25, 2023 · Updated Sep 12, 2024

Command injection in TOTOLINK X6000R firmware 9.4.0cu.652_B20230116 allows attackers to execute router commands via sub_422BD4. The public record identifies sub_422BD4 as the injection locus but does not disclose which input reaches a command interpreter or how it is neutralized incorrectly. Adjacent-network access is required, but no privileges or user interaction are needed; successful exploitation executes attacker-chosen commands on the router.
