CVE-2018-15477
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedmyStrom WiFi Switch V1 devices before 2.66 did not sanitize a parameter received from the cloud that was used in an OS command. Malicious servers were able to run operating system commands on the device.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidencemyStrom WiFi Switch V1 devices before firmware version 2.66 contain a command injection vulnerability where a parameter received from the cloud is not sanitized before being used in an operating system command, allowing malicious servers to execute arbitrary OS commands on the device.

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.
-
Confirm device modelIdentify the physical device or check device documentation to confirm it is a myStrom WiFi Switch V1. Do not confuse with V2 or other myStrom products.Affected if Device is a myStrom WiFi Switch V1
-
Check firmware versionAccess the device web interface or use the myStrom mobile app to view the current firmware version installed on the device.Affected if Firmware version is below 2.66 (for example, 2.65, 2.64, etc.)
-
Verify cloud connectivity is enabledCheck the device configuration settings to determine if the device is configured to communicate with myStrom cloud servers for remote control.Affected if Cloud connectivity is enabled and the device communicates with myStrom servers
The device is affected if it is a myStrom WiFi Switch V1 running firmware version below 2.66 and has cloud connectivity enabled, allowing remote commands to reach the device.

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.
dbcve · scoped2.66
Update myStrom WiFi Switch V1 devices to firmware version 2.66 or later to patch the command injection vulnerability. If updating is not possible, restrict network communication to trusted myStrom cloud servers only.
Firmware version 2.66 or later for myStrom WiFi Switch V1
- Contact myStrom vendor support or visit the official myStrom website to obtain firmware version 2.66 or later for WiFi Switch V1
- Follow the vendor-provided instructions to apply the firmware update to the device
- After upgrading, verify the device is running firmware version 2.66 or later
- Ensure the device is connected to trusted cloud servers only
