Summary

CVE-2026-62543 is a critical vulnerability in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology (part of Oracle Hyperion). It allows an unauthenticated, remote attacker with network access via HTTP to fully compromise and take over the affected system. Oracle rates it 9.8 (Critical) under CVSS v3.1.

Technical details

  • Root cause lies in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology.
  • Oracle describes the flaw as "easily exploitable," requiring no authentication and no user interaction.
  • Attack vector is the network, via HTTP, meaning exploitation can be attempted directly against internet-exposed Hyperion instances.
  • Successful exploitation results in takeover of Oracle Hyperion Infrastructure Technology, with high impact to confidentiality, integrity, and availability.
  • Oracle has not published a detailed technical root-cause writeup (e.g., specific injection or deserialization mechanism) beyond the advisory summary.

Affected software

  • Oracle Hyperion Infrastructure Technology, version 11.2.25.0.000 (Oracle Hyperion product family).

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: Apply the fix provided in Oracle’s August 2026 Critical Patch Update for Oracle Hyperion Infrastructure Technology 11.2.25.0.000.
  • If patching cannot be performed immediately: restrict network/HTTP access to Hyperion Infrastructure Technology components to trusted internal networks only, and place the service behind a firewall or VPN until the patch is applied, since Oracle has not published an alternative workaround.
  • Monitor Hyperion-facing systems for anomalous HTTP requests as an interim compensating control.

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.
