CVE-2024-35401

Command execution via crafted firmware filename

Published May 28, 2024 · Updated Jul 9, 2026

Command injection in TOTOLINK CP900L firmware 4.1.5cu.798_B20221228 allows local users to execute commands via a crafted firmware filename. UploadFirmwareFile incorporates the attacker-controlled FileName value into an operating-system command without neutralizing command syntax. Local access to the firmware-upload path is required, and injected commands can read or alter device data and interrupt service.
