CVE-2023-3270
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 · uneditedExposure of Sensitive Information to an Unauthorized Actor in the SICK ICR890-4 could allow an unauthenticated remote attacker to retrieve sensitive information about the system.
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 SICK ICR890-4 industrial scanner contains an information disclosure vulnerability allowing unauthenticated remote attackers to retrieve sensitive system information. This appears to be a classic sensitive information exposure flaw in the device's web interface, API, or network service that fails to properly restrict access to system data.

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 the installed firmware versionAccess the device's web interface or management console and navigate to System Information or About page to view the firmware version. Alternatively, use the device's API endpoint for system info if available.Affected if The firmware version displayed is lower than 2.5.0 (e.g., 2.4.x, 2.3.x, etc.)
-
Verify web interface accessibilityAttempt to access the device's web interface from an untrusted network location using a browser or HTTP client (e.g., http://[device-ip]/). Check if the login page or any system information loads without requiring credentials.Affected if The web interface is reachable from networks outside the trusted management VLAN without authentication being enforced first.
-
Test for unauthenticated information disclosureSend HTTP requests to common API endpoints on the device (such as /api/system, /api/status, or /api/info) using a tool like curl or a browser. Observe if sensitive system data (device configuration, network settings, or diagnostic information) is returned without authentication tokens or login.Affected if The device returns sensitive system information or configuration data in response to unauthenticated API requests.
-
Review network exposure of the deviceScan the network to confirm which IP addresses and ports the device is listening on. Check if ports for the web interface (typically HTTP/HTTPS ports 80/443 or custom ports) are exposed to untrusted networks.Affected if The device's management web interface ports are listening on IP addresses accessible from untrusted network segments.
You are affected if the device firmware version is below 2.5.0 AND the web interface or API is accessible from an untrusted network, allowing unauthenticated retrieval of sensitive system information.

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 · scoped2.5.0
SICK has released firmware updates for the ICR890-4; organizations should apply the latest patches immediately. Additionally, network segmentation and firewall rules should restrict access to the device to trusted networks only as a defense-in-depth measure.
ICR890-4 Firmware 2.5.0 or later
- Upgrade the ICR890-4 device firmware to version 2.5.0 or later.
- After upgrading, verify that the device is functioning correctly and that the vulnerability is remediated.
- Consult SICK's official firmware release notes for the ICR890-4 to confirm the fix for CVE-2023-3270 is included in the target version.
