In Weidmueller Industrial WLAN devices in multiple versions an exploitable command injection vulnerability exists in the hostname functionality. A specially crafted entry to network configuration information can cause execution of arbitrary system commands, resulting in full control of the device. An attacker can send various requests while authenticated as a high privilege user to trigger this vulnerability.
