Last modified
CVE-2021-33530 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 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. 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 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.
