Who should care

Administrators of SendQuick Entera and Avera SMS gateway appliances, security operations teams, and organizations that store sensitive or regulated communications in SMS logs should pay attention, especially if the devices are reachable from untrusted networks.

Technical summary

The supplied NVD record describes unauthenticated access to SMS logs on SendQuick Entera and Avera firmware before 2HF16. NVD maps the issue to CWE-532. The recorded CVSS score is 6.2 (Medium), with confidentiality impact as the primary concern and no integrity or availability impact noted. The source CVSS vector is provided as CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N; this debrief preserves the source data as supplied.

Defensive priority

Medium-high. This is not code execution, but it can expose sensitive SMS contents and operational metadata without authentication. Prioritize if the appliances are internet-facing, contain customer or compliance-sensitive messages, or are used in regulated environments.

Recommended defensive actions

  • Upgrade affected SendQuick Entera and Avera devices to 2HF16 or later, or otherwise apply the vendor-fixed version identified for the appliance in use.
  • Restrict or eliminate unauthenticated access paths to any SMS log retrieval function.
  • Verify that access controls, authentication, and authorization are enforced on all administrative and log-download interfaces.
  • Review whether SMS logs were exposed historically and assess whether any sensitive data, credentials, or tokens were recorded there.
  • Check for suspicious or unexpected log-download activity and preserve audit records for investigation.
  • Inventory deployed firmware versions and confirm which devices match the affected CPEs in the NVD record.
  • Purge or rotate any sensitive material that may have been exposed through logs, and consider retention minimization for future logs.
