Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check WeMo Insight Switch firmware versionOpen the WeMo mobile app, select the WeMo Insight Switch device, and navigate to Settings or Device Information to view the firmware version. Alternatively, access the device's web interface by navigating to its IP address and check the firmware version in the settings.Affected if The displayed firmware version is 2.00.11396 or any version prior to 2.00.11396 (for example, 2.00.11390, 1.00.xxxx, etc.)
-
Verify libbelkin_api.so component existsIf you have shell access to the device (via telnet, SSH, or debug interface), search for the file libbelkin_api.so in the filesystem (commonly in /lib or /usr/lib directories).Affected if The file libbelkin_api.so exists on the device and the firmware version is 2.00.11396 or prior
-
Cross-reference firmware with vendor release notesVisit Belkin's support website or check the WeMo app for any firmware update announcements. Compare your installed version against the version history to confirm it is <= 2.00.11396.Affected if No firmware update beyond 2.00.11396 has been applied to the device
The device is affected if the WeMo Insight Switch is running firmware version 2.00.11396 or any earlier version, as this indicates the vulnerable libbelkin_api.so component is present.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data2.00.11396
Update WeMo Insight Switch firmware to a version newer than 2.00.11396; if no update is available, network-isolate the device to limit physical/local attack vectors.
