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 · unedited
Crestron TSW-1060, TSW-760, TSW-560, TSW-1060-NC, TSW-760-NC, and TSW-560-NC devices before 2.001.0037.001 allow unauthenticated remote code execution via command injection in Crestron Toolbox Protocol (CTP).

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 confidence

Unauthenticated command injection in the Crestron Toolbox Protocol (CTP) allows remote attackers to execute arbitrary operating system commands on affected Crestron touch panel devices (TSW-1060, TSW-760, TSW-560, and NC variants) by injecting malicious commands into CTP requests, leading to complete device compromise without any authentication credentials.

MitigationUpgrade affected Crestron TSW touch panel devices to firmware version 2.001.0037.001 or later to remediate the command injection vulnerability. If patching is not immediately possible, restrict network access to CTP ports and isolate affected devices from untrusted networks.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify your device model
    Locate the model number on the device label or check the device inventory documentation. Confirm it is one of: TSW-1060, TSW-760, TSW-560, or an NC-series variant.
    Affected if The device is NOT one of these models, then this CVE does not apply to your device.
  2. Check the Crestron Toolbox Protocol firmware version
    Access the device admin interface or use Crestron Toolbox software to retrieve the firmware version. Navigate to the system information or firmware update section.
    Affected if The installed firmware version is lower than 2.001.0037.001, the device is running a vulnerable version.
  3. Determine if CTP service is enabled
    Check the device network configuration or service status to see if the Crestron Toolbox Protocol (CTP) service is active and listening on the network.
    Affected if CTP is disabled or not configured, the command injection attack surface may not be exposed, but the device remains vulnerable if CTP is later enabled.
  4. Assess network exposure of CTP ports
    Review firewall rules and network segmentation to determine if CTP ports (typically port 41795 for CTP) are accessible from untrusted network segments or the internet.
    Affected if CTP ports are exposed to untrusted networks without network segmentation, the device is at higher risk of remote exploitation.

You are affected if your device is a TSW-1060, TSW-760, TSW-560, or NC variant AND the firmware version is below 2.001.0037.001, regardless of CTP accessibility.

Upgrade available Upgrade to 2.001.0037.001 or later
Fixed in 2.001.0037.001
Interim mitigation

Upgrade affected Crestron TSW touch panel devices to firmware version 2.001.0037.001 or later to remediate the command injection vulnerability. If patching is not immediately possible, restrict network access to CTP ports and isolate affected devices from untrusted networks.

Recommended fix High confidence

2.001.0037.001

  1. 1. Obtain the fixed firmware version 2.001.0037.001 from the official Crestron support portal (support.crestron.com)
  2. 2. Review the Crestron firmware upgrade documentation for your specific device model (TSW-1060, TSW-760, TSW-560, TSW-1060-NC, TSW-760-NC, or TSW-560-NC)
  3. 3. Backup current device configuration if applicable
  4. 4. Upload the firmware file 2.001.0037.001 to the device using the Crestron Toolbox software or device web interface
  5. 5. Verify the firmware upgrade was successful by checking the device firmware version
  6. 6. Confirm the Crestron Toolbox Protocol service is functioning normally after upgrade
Caveat Minimal expected; security patches typically maintain backward compatibility
