CVE-2021-34592Network attack vector

Authenticated command execution via web input fields

Published Apr 27, 2022 · Updated Sep 16, 2024

Command injection in Bender CC612, CC613, ICC15xx, and ICC16xx firmware allows remote authenticated users to execute shell commands. The web interface passes shell metacharacters from unspecified configuration input fields to operating-system commands without adequate neutralization; public records do not identify the affected parameters or handler. Valid web-interface credentials and network access are required, and successful commands can read or alter controller data and interrupt controller operation.
