CVE-2024-42495 Hughes Network Systems CVE debrief

CVE-2024-42495 (CVSS 6.5, Medium) describes a cleartext credential transmission vulnerability in Hughes Network Systems WL3000 Fusion Software, published 2024-09-05. Device configuration credentials were transmitted via an unencrypted protocol, enabling read-only access to network and terminal configuration data for attackers with adjacent network access. The attack vector is adjacent (AV:A), requires no privileges or user interaction (PR:N/UI:N), and results in high confidentiality impact (C:H) with no integrity or availability impact. Hughes Network Systems has patched this vulnerability; no user action is required. Organizations should contact Hughes customer support with any questions.

Recommended defensive actions

  • Contact Hughes Network Systems customer support if questions remain about patch deployment status for WL3000 Fusion Software.
  • Verify WL3000 Fusion Software is running version 2.7.0.10 or later.
  • Segment satellite terminal management networks from untrusted or guest networks to limit adjacent attack vectors.
  • Monitor network traffic for unencrypted credential exchanges on management interfaces.
  • Apply CISA ICS recommended practices for defense-in-depth strategies in satellite/SCADA environments.

Evidence notes

CISA ICS Advisory ICSA-24-249-01 confirms Hughes Network Systems patched the vulnerability with no user action required. CVSS 3.1 vector AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N indicates adjacent network access is required.
