CVE-2023-50983Network attack vector

Unauthenticated command execution via sysScheduleRebootSet

Published Dec 20, 2023 · Updated Jul 9, 2026

Command injection in Tenda i29 firmware 1.0.0.5 allows remote attackers to execute arbitrary commands via sysScheduleRebootSet. Public records name sysScheduleRebootSet but do not disclose the affected request parameter or the command-construction operation that mishandles it. Network access without authentication or user interaction is sufficient, and successful exploitation permits full device compromise.
