Who should care

Organizations that operate or support affected New Rock Technologies cloud-connected voice and IP-telephony devices, especially OM500 IP-PBX, MX8G VoIP Gateway, and NRP1302/P Desktop IP Phone deployments.

Technical summary

The supplied CISA CSAF advisory states that the affected products' Cloud MQTT service allows wildcard topic subscription. In that configuration, an attacker may be able to observe service communications and obtain sensitive information. The supplied CVSS vector is CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, indicating a confidentiality-focused issue with no integrity or availability impact in the advisory data.

Defensive priority

Moderate. Prioritize inventorying affected devices, validating whether the Cloud MQTT service is exposed or needed, and applying compensating controls because the supplied advisory does not identify a vendor fix and says New Rock Technologies had not responded to CISA's mitigation requests.

Recommended defensive actions

  • Identify all deployments of the affected New Rock Technologies products and confirm whether they match the advisory's affected versions.
  • Review whether Cloud MQTT functionality is required; if not, disable or isolate it according to vendor guidance and internal change control.
  • Restrict network access to management and service interfaces using segmentation and least-privilege network rules.
  • Monitor service and MQTT-related traffic for unexpected subscriptions or anomalous access patterns.
  • Contact New Rock Technologies customer support for current mitigation or remediation guidance, as directed by the advisory.
  • Follow CISA ICS recommended practices and other official defense-in-depth guidance for compensating controls.

Evidence notes

The CISA CSAF advisory ICSA-25-030-02 (published 2025-01-30) is the primary source and names the affected products and vulnerability description. The advisory notes the Cloud MQTT wildcard subscription issue and includes the CVSS 3.1 vector CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N. It also states that New Rock Technologies had not responded to requests to work with CISA to mitigate the vulnerabilities.
