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
OliveTin gives access to predefined shell commands from a web interface. From 3000.2.0 until 3000.17.0, the service/internal/executor/arguments.go checkShellArgumentSafety function does not treat regex: custom argument types as unsafe for Shell mode actions, allowing values that pass typeSafetyCheckRegex to be interpolated by wrapCommandInShell into an sh -c command string and enabling OS command injection. This issue is fixed in version 3000.17.0.

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.

How this class of weakness works · CWE-78

User input reaches a shell or system command without being fully separated from the command itself, so an attacker can append their own instructions. Because these run with the application's privileges, it often means full control of the host. The lasting fix is to avoid the shell entirely — call APIs directly and pass arguments as data, never as concatenated strings.

Recommended fix High confidence

OliveTin version 3000.17.0

  1. Identify the currently running OliveTin version using 'docker ps' or checking the container/service configuration
  2. Stop or scale down the current OliveTin container/service
  3. Pull the updated OliveTin image tagged 3000.17.0 (e.g., 'docker pull olivetin/olivetin:3000.17.0' or update the docker-compose/k8s manifest to reference 3000.17.0)
  4. Update the deployment configuration to use version 3000.17.0
  5. Start the OliveTin container/service with the new version
  6. Verify the service is running correctly and that the web interface is accessible
  7. Test that the previously vulnerable regex: argument type configurations now properly reject shell metacharacters
