CVE-2023-23551
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 · uneditedControl By Web X-600M devices run Lua scripts and are vulnerable to code injection, which could allow an attacker to remotely execute arbitrary code.
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 · moderate confidenceThe Control By Web X-600M devices contain a code injection vulnerability in their Lua scripting engine. Attackers can inject malicious Lua code through user-supplied input processed by the device's script functionality, leading to arbitrary code execution on the affected device with the privileges of the web server process.

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 modelAccess the device's web interface and navigate to the status or system information page to verify the device is a Control By Web X-600M series controllerAffected if Device is not a Control By Web X-600M
-
Check firmware versionLocate the firmware version in the device's web interface (typically under System Info, Status, or About section) and compare it to the affected rangeAffected if Firmware version is less than 1.16.00
-
Verify Lua scripting statusAccess the device's configuration or script management interface to determine whether the Lua scripting engine is enabledAffected if Lua scripting functionality is enabled on the device
-
Inspect configured scriptsReview all user-defined Lua scripts stored on the device for suspicious or unexpected code patterns, especially scripts that process user-supplied inputAffected if Any Lua script contains code that processes external input without proper sanitization
The device is affected if it is an X-600M running firmware below version 1.16.00 and has Lua scripting enabled, regardless of whether malicious scripts are currently present.
Generated from the published advisory. Verify against your own configuration.
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 · scoped1.16.00
Apply the vendor-supplied firmware patch when available; alternatively, disable Lua scripting functionality if not required, or restrict network access to the device's management interface to minimize attack surface.
Firmware version 1.16.00 or later
- 1. Identify the current firmware version of the Control By Web X-600M device by accessing the device web interface or using the device's status page
- 2. Download the firmware version 1.16.00 or later from the official Control By Web website or support portal
- 3. Access the device's administration interface and navigate to the firmware upgrade section
- 4. Upload and apply the new firmware version 1.16.00 or later
- 5. After the upgrade completes, verify the device is functioning normally and confirm the new firmware version is installed
- 6. Restart the device if required to ensure all changes take effect
