CVE-2021-38470Network attack vector

Admin-level command execution via ping input injection

Published Oct 19, 2021 · Updated Sep 17, 2024

OS command injection in InHand Networks InRouter615-S 2.3.0.r4724 and 2.3.0.r4870 allows remote authenticated users to execute commands. The router's ping tool passes attacker-controlled input to an operating-system command without adequately neutralizing command syntax. Administrative access to the network management interface is required, and successful exploitation runs commands with the device's privileges.
