Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.47% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Hewlett Packard Enterprise (HPE) EdgeConnect SD-WAN Orchestrator and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 30 daysRemediation target: Within 180 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

The vendor explicitly identifies these products as affected by this CVE.

  • EdgeConnect SD-WAN Orchestrator
Summary
Self-hosted EdgeConnect SD-WAN Orchestrator instances prior to the versions resolved in this advisory were found to have shared static SSH host keys for all installations. This vulnerability could allow an attacker to spoof the SSH host signature and thereby masquerade as a legitimate Orchestrator host. Orchestrator-as-a-Service (OaaS) instances are not affected by this vulnerability.
Remediation
PLEASE NOTE - To fully patch the vulnerabilities disclosed above, including lower severity authenticated vulnerabilities that require existing administrative access, customers must upgrade to the following branch and version: - Orchestrator 9.3.x: Orchestrator 9.3.1 (all builds) and above (expected to be available end of September 2023) For those who choose to implement workarounds and other security controls documented in the details sections above, all vulnerabilities with a CVSS score of 7.0 and above are addressed by upgrading to the following branches and versions of EdgeConnect SD-WAN Orchestrator: - EdgeConnect SD-WAN Orchestrator (self-hosted, on-premises) - EdgeConnect SD-WAN Orchestrator (self-hosted, public cloud IaaS) - EdgeConnect SD-WAN Orchestrator-as-a-Service - EdgeConnect SD-WAN Orchestrator-SP Tenant Orchestrators - EdgeConnect SD-WAN Orchestrator Global Enterprise Tenant Orchestrators - Orchestrator 9.3.x: Orchestrator 9.3.1 (all builds) and above (expected to be available end of September 2023) - Orchestrator 9.2.x: Orchestrator 9.2.6 (all builds) and above - Orchestrator 9.1.x: Orchestrator 9.1.8 (all builds) and above - EdgeConnect SD-WAN Orchestrator-SP Tenant Orchestrators - Service providers must upgrade all tenants to a patched version listed above. HPE Aruba Networking does not evaluate or patch product branches that have reached their End of Maintenance (EoM) milestone. Supported branches as of the publication date of this advisory are: - EdgeConnect SD-WAN Orchestrator 9.3.x - EdgeConnect SD-WAN Orchestrator 9.2.x - EdgeConnect SD-WAN Orchestrator 9.1.x For more information about Aruba's End of Support policy visit: https://www.arubanetworks.com/support-services/end-of-life/

What, why and how

EdgeConnect SD-WAN Orchestrator instances prior to the versions resolved in this advisory were found to have shared static SSH host keys for all installations. This vulnerability could allow an attacker to spoof the SSH host signature and thereby masquerade as a legitimate Orchestrator host.

What

EdgeConnect SD-WAN Orchestrator instances prior to the versions resolved in this advisory were found to have shared static SSH host keys for all installations. This vulnerability could allow an attacker to spoof the SSH host signature and thereby masquerade as a legitimate Orchestrator host.

Why

A credential embedded in the product can be recovered or reused across installations instead of being unique to one deployment.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Use of Hard-coded Credentials → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Network
Privileges required
None: unauthenticated exploitation is possible
User interaction

Attack complexity
High: exploitation depends on specific conditions
Security boundary

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-798 ↗

CWE-798: Use of Hard-coded Credentials. The product contains hard-coded credentials, such as a password or cryptographic key.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACHighAttack complexity: Successful exploitation depends on specific conditions outside the attacker's direct control.PRNonePrivileges required: The attacker does not need an account or existing privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.ANoneAvailability impact: No direct loss is represented by this metric.
