Summary

CVE-2026-63455 is a critical authentication bypass affecting the REST API interface of HPE Networking (EdgeConnect) SD-WAN Orchestrator. Multiple flaws allow an unauthenticated remote attacker to bypass web authentication mechanisms and access system functions. HPE rates the issue CVSS 9.8 (Critical).

Technical details

  • Root cause: Missing authentication for critical function (CWE-306) in the Orchestrator REST API interface, permitting authentication to be bypassed via spoofed HTTP headers.
  • Trigger conditions: An attacker sends crafted requests to the network-reachable REST API; no valid credentials, prior authentication, or user interaction is required.
  • Attack vector: Network (remote), low complexity, unauthenticated.
  • Impact: Bypass of web authentication and access to protected system functions, with high impact to confidentiality, integrity, and availability of the Orchestrator.

Affected software

  • HPE EdgeConnect SD-WAN Orchestrator 9.6.2.00000 up to and including 9.6.2.40208
  • HPE EdgeConnect SD-WAN Orchestrator 9.6.3.00000 up to and including 9.6.3.40137

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade to a fixed release above the affected ranges as identified in HPE security bulletin HPESBNW05100 — a build later than 9.6.2.40208 for the 9.6.2 branch, and later than 9.6.3.40137 for the 9.6.3 branch.
  • If no patch can be applied yet: Restrict network access to the Orchestrator management and REST API interface, limiting reachability to trusted management networks and removing exposure to the public internet until the update is deployed.

How IONIX identifies potentially affected assets

IONIX matches the following signals against data already collected when it crawled the asset; identifying the technology sends no request beyond that crawl.

  • Content-Security-Policy response header: silverpeaksystems.net, portal.silverpeak.cloud
  • Raw response body: Welcome to SD-WAN Orchestrator

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
