Technical details

The vulnerability is an OS command injection (CWE-78) in the /index.php/ajax/save_iodd_parameters endpoint. It requires valid operator-level credentials to exploit, but allows arbitrary command execution with root privileges on the device. The attack vector is network-based with no user interaction required beyond providing credentials. An authenticated operator can craft malicious payloads in endpoint parameters to break out of command context and execute arbitrary shell commands. Patches are available in firmware version 1.7.4 and later for all affected models.
