CVE-2020-2076
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 · uneditedSICK Package Analytics software up to and including version V04.0.0 are vulnerable to an authentication bypass by directly interfacing with the REST API. An attacker can send unauthorized requests, bypass current authentication controls presented by the application and could potentially write files without authentication.
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 confidenceSICK Package Analytics software versions up to V04.0.0 contain an authentication bypass vulnerability in the REST API. Attackers can directly interface with the REST API endpoint without proper authentication, bypassing existing authentication controls and potentially writing files to the system without credentials.

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.
-
Identify SICK Package Analytics versionLocate the installation directory or check the software's built-in about/version information. Common locations include the program files folder or the application's main interface under Help > About. Record the exact version number displayed.Affected if The installed version is V04.0.0 or any version lower (e.g., V03.x.x, V02.x.x)
-
Confirm REST API component is presentExamine the application installation for REST API components, typically found in subdirectories named 'api', 'rest', 'webapi', or similar. Check configuration files for REST API service definitions or endpoint listings.Affected if REST API components exist and are installed as part of the SICK Package Analytics deployment
-
Verify REST API network accessibilityIdentify the network port used by the REST API (commonly ports 8080, 8443, or application-specific ports). Use 'netstat -an' or similar network tools to determine if the REST API service is listening on network interfaces. Check if it binds to 0.0.0.0 (all interfaces) rather than localhost only.Affected if The REST API is listening on accessible network interfaces, especially on non-localhost addresses
-
Test unauthenticated REST API accessSend an HTTP request to the REST API endpoint without providing any authentication credentials. For example, use curl or a browser to access common REST paths such as /api/status, /api/config, or /api/data. Observe whether the request succeeds and returns data without authentication tokens or credentials.Affected if The REST API returns successful responses (HTTP 200 or similar) without requiring authentication, indicating the authentication bypass is present
If SICK Package Analytics version is V04.0.0 or lower AND the REST API is network-accessible AND it accepts unauthenticated requests, the environment is vulnerable to CVE-2020-2076.

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 dataUpgrade to a version newer than V04.0.0 that contains the security patch. Until then, restrict network access to the REST API interface and implement additional access controls at the network layer.
