Last modified
CVE-2021-33532 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. In Weidmueller Industrial WLAN devices in multiple versions an exploitable command injection vulnerability exists in the iw_webs functionality. A specially crafted diagnostic script file name can cause user input to be reflected in a subsequent iw_system call, resulting in remote control over the device. EPSS estimates a 1.73% chance of exploitation in the next 30 days.
Description
In Weidmueller Industrial WLAN devices in multiple versions an exploitable command injection vulnerability exists in the iw_webs functionality. A specially crafted diagnostic script file name 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.
