CVE-2023-52038Network attack vector

Unauthenticated command execution via sub_415C80

Published Jan 24, 2024 · Updated May 30, 2025

Command injection in TOTOLINK X6000R firmware 9.4.0cu.852_B20230719 allows remote attackers to execute arbitrary commands over the network. The public record identifies sub_415C80 as the command-injection locus but does not disclose the input parameter or command-construction operation. No authentication or user interaction is required, and successful exploitation gives control of command execution on the router.
