CVE-2023-2564
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 · uneditedOS Command Injection in GitHub repository sbs20/scanservjs prior to v2.27.0.
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 confidenceOS Command Injection vulnerability in scanservjs versions prior to v2.27.0 allows remote attackers to execute arbitrary operating system commands on the host server. The CVSS 10 score indicates this is remotely exploitable with no authentication required, likely through unsanitized user input being passed to system shell calls.

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 if scanservjs is installedLook for scanservjs application directories, Docker containers, or running processes on the server. Check common deployment locations or your container orchestration system if running as a container.Affected if scanservjs is found running on the system
-
Determine the installed scanservjs versionCheck the version of scanservjs by inspecting package.json, a VERSION file, Docker image tag, or the /about/version endpoint if the web interface is accessible. Compare your version to the affected range of versions prior to v2.27.0.Affected if The installed version is lower than v2.27.0
-
Verify the web interface is accessibleCheck if the scanservjs web interface is exposed on a network. Attempt to access the HTTP/HTTPS endpoint if known. Since this vulnerability is remotely exploitable with no authentication, network accessibility is required for exploitation.Affected if The scanservjs web interface is reachable from a network where attackers could send malicious requests
You are affected if scanservjs is running and its version is below v2.27.0 with the web interface network-accessible.

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 · scoped2.27.0
Upgrade to scanservjs v2.27.0 or later. If immediate patching is not possible, disable or restrict any functionality that passes user input to system commands and implement strict input validation.
v2.27.0
- 1. Check current scanservjs version by running `npm list scanservjs` or checking package.json
- 2. Update scanservjs to version 2.27.0 or later using `npm install scanservjs@^2.27.0` or your package manager's upgrade command
- 3. If using a packaged version (e.g., Docker), pull the image tag corresponding to v2.27.0 or later
- 4. Restart the scanservjs service to apply the update
- 5. Verify the upgrade was successful by checking the version again
