Summary

CVE-2026-62539 is a critical, easily exploitable vulnerability in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. It allows an unauthenticated attacker with network access via HTTP to fully compromise the affected system, with Oracle stating that successful exploitation "can result in takeover" of Hyperion Infrastructure Technology. The flaw carries a CVSS v3.1 base score of 9.8 (Critical) and was disclosed as part of Oracle’s August 2026 Critical Patch Update.

Technical details

  • Root cause: A flaw in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology (Oracle has not published low-level technical root-cause details beyond the component name).
  • Trigger conditions: No authentication, privileges, or user interaction are required to trigger the vulnerability.
  • Attack vector: Network-based, exploitable over HTTP against the exposed Hyperion service.
  • Impact: Complete compromise of confidentiality, integrity, and availability — Oracle describes the outcome as takeover of the affected system.

Affected software

  • Oracle Hyperion Infrastructure Technology, version 11.2.25.0.000

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 Oracle Hyperion patches released in the August 2026 Critical Patch Update (CPU) to remediate CVE-2026-62539. Oracle strongly recommends applying CPU fixes as soon as possible.
  • If immediate patching is not possible: Restrict network access to Hyperion Infrastructure Technology interfaces (e.g., via firewall rules or VPN) so they are not reachable from untrusted networks, and monitor exposed HTTP endpoints for anomalous activity until the patch can be applied.

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.
