Remote device takeover

The advisory states that successful exploitation of the vulnerabilities could allow an attacker to take control over the device. It does not say whether the flaws have been exploited in the wild.

Affected products

The advisory concerns the Xiiaozet LK100W. No specific version numbers, firmware releases, or additional products are named in the advisory.

What to do

Determine whether any Xiiaozet LK100W devices are present in your operational technology environment.
Apply any available firmware updates or mitigations supplied by the vendor.
Implement network segmentation to limit exposure of the device to untrusted networks.
Follow vendor guidance for secure configuration of the LK100W.
Monitor the vendor’s official channels and CISA’s ICS advisories for updated information.

Organizations operating industrial control systems or medical devices should treat this class of vulnerability as a priority for asset inventory and risk reduction.
