WL3000 Fusion Software: Missing Encryption of Sensitive Data

Published Updated By the CyberSecBulletin desk

CVE-2024-42495 is a high-severity missing encryption of sensitive data vulnerability in WL3000 Fusion Software from Hughes Network Systems, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 2.7.0.10 as the first without the flaw, so updating WL3000 Fusion Software to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.3% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update WL3000 Fusion Software to 2.7.0.10 or a later version.
  2. Update Fusion to 2.7.0.10 or a later version.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Credentials to access device configuration were transmitted using an unencrypted protocol. These credentials would allow read-only access to network configuration information and terminal configuration data.

The underlying weakness: Missing Encryption of Sensitive Data

The product does not encrypt sensitive or critical information before storage or transmission.

How developers prevent this class of flaw

  • Clearly specify which data or resources are valuable enough that they should be protected by encryption. Require that any transmission or storage of this data/resource should use well-vetted encryption algorithms.
  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
  • When using industry-approved techniques, use them correctly. Don't cut corners by skipping resource-intensive steps (CWE-325). These steps are often essential for preventing common attacks.
