Technical summary

CVE-2024-42418 affects Avtec Outpost 0810 and Outpost Uploader Utility versions prior to 5.0.0. The products ship with a default cryptographic key that enables decryption of sensitive information by unauthenticated network attackers. The vulnerability has network attack vector, low attack complexity, and requires no privileges or user interaction. Confidentiality impact is rated HIGH with no integrity or availability impact. Remediation requires updating to Outpost v5.0.0 or later, with additional steps to reset user authentication when upgrading the Uploader Utility component.

Defensive priority

HIGH

Recommended defensive actions

  • Upgrade Avtec Outpost to version 5.0.0 or later to resolve the default cryptographic key vulnerability
  • When upgrading Outpost Uploader Utility to version 5.0.0 or later, reset the user list to default per Avtec's Outpost Uploader Utility User Guide
  • Restrict network access to port 80 or disable the web interface if not required
  • Check for coupled Scout firmware versions prior to 5.8.1 and update to latest firmware if present
  • Review and apply CISA ICS recommended practices for defense-in-depth security controls

Evidence notes

CISA ICS Advisory ICSA-24-235-04 documents this vulnerability affecting Avtec Outpost 0810 and Outpost Uploader Utility versions below 5.0.0. The advisory confirms the default cryptographic key weakness and provides vendor remediation guidance.
