CVE-2024-23061Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized minute parameter

Published Jan 11, 2024 · Updated Jun 20, 2025

Command injection in TOTOLINK A3300R 17.0.0cu.557_B20221024 allows remote attackers to execute OS commands via a crafted minute value. The setScheduleCfg handler passes minute through Uci_Set_Str, which splices it into a UCI command before CsteSystem sends it to execv without neutralizing shell metacharacters. No privileges or user interaction are required; the demonstrated payload writes command output into the web root, establishing command execution and file modification.
