Security readout for executives and security teams

Plain-English summary

Avaya Aura Orchestration Designer 7.x before 7.2.3 has an XML parsing flaw in its web UI. A logged-in remote attacker could make the application read information stored on the affected system. The issue is high severity because confidentiality impact is high and no user interaction is required.

Executive priority

Prioritize remediation for internet-reachable or broadly accessible deployments. This is not marked as known exploited in the provided sources, but the high CVSS score and potential system information exposure justify scheduled remediation.

Technical view

CVE-2020-7035 is a CWE-611 XML External Entity vulnerability in the web-based UI of Avaya Aura Orchestration Designer. CVSS 3.1 is 8.1 with network access, low complexity, low privileges, no user interaction, high confidentiality impact, no integrity impact, and high availability impact.

Likely exposure

Exposure is likely limited to organizations running Avaya Aura Orchestration Designer 7.x earlier than 7.2.3, especially where the web UI is reachable by authenticated users over the network.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires authenticated remote access, which lowers exposure compared with unauthenticated bugs but still matters if low-privilege accounts exist.

Researcher notes

Evidence identifies XXE in the web UI and affected 7.x versions before 7.2.3. The bundle does not provide exploit details, indicators of compromise, or detailed vendor workaround text, so validation should stay version- and exposure-focused.

Mitigation direction

  • Upgrade Avaya Aura Orchestration Designer to 7.2.3 or later per vendor guidance.
  • Restrict web UI access to trusted administrative networks and users.
  • Review accounts with access to the Orchestration Designer web UI.
  • Monitor Avaya guidance for any additional hardening or remediation notes.

Validation and detection

  • Inventory Avaya Aura Orchestration Designer deployments and record exact versions.
  • Flag any 7.x deployment earlier than 7.2.3 as affected.
  • Confirm whether the web UI is reachable from untrusted networks.
  • Review authentication logs for unusual access to the web UI.
