In Weidmueller Industrial WLAN devices in multiple versions an exploitable command injection vulnerability exists in encrypted diagnostic script functionality of the devices. A specially crafted diagnostic script file can cause arbitrary busybox commands to be executed, resulting in remote control over the device. An attacker can send diagnostic while authenticated as a low privilege user to trigger this vulnerability.
