CVE-2024-36295Network attack vector

Authenticated command execution via crontab injection

Published Jan 14, 2025 · Updated Jan 14, 2025

Command injection in qos.cgi in Wavlink AC3000 M33A8.V5030.210505 allows remote authenticated users to execute arbitrary commands. The qos_sta_settings function writes the time_control POST value to /vendor/time_control_sta_list without neutralizing shell syntax; sta_time_control.sh later places attacker-controlled fields into crontab entries. A valid administrator session and successful WAN-based NTP synchronization are required before the injected scheduled commands execute.
