HighCVSS 8.8/10Last modified Jun 17, 2026

Description

In Weidmueller Industrial WLAN devices in multiple versions an exploitable command injection vulnerability exists in the iw_webs functionality. A specially crafted iw_serverip parameter can cause user input to be reflected in a subsequent iw_system call, resulting in remote control over the device. An attacker can send commands while authenticated as a low privilege user to trigger this vulnerability.
