CVE-2024-45721Network attack vector

Root command execution via HOST name injection

Published Dec 23, 2024 · Updated Dec 24, 2024

OS command injection in three Sharp router models allows remote authenticated users to execute arbitrary commands with root privileges. The HOST name screen passes administrator-controlled input to an OS command without neutralizing command syntax in home 5G HR02 S5.82.00 and earlier, Wi-Fi STATION SH-52B S3.87.11 and earlier, and Wi-Fi STATION SH-54C S6.60.00 and earlier. Exploitation requires administrative access from a client connected to the router by Wi-Fi, USB, or Ethernet.
