Summary

CVE-2026-70741 is a critical vulnerability in the Server component of Oracle Hyperion Financial Reporting. It allows an unauthenticated attacker with network access via RMI to compromise the application, gaining unauthorized creation, deletion, or modification access to critical data and complete access to all data accessible within Hyperion Financial Reporting. Oracle rates this as CRITICAL with a CVSS 3.1 base score of 9.1.

Technical details

  • Root cause: an exploitable flaw in the Hyperion Financial Reporting Server component reachable over the RMI protocol.
  • Trigger conditions: no authentication or user interaction is required; the attacker only needs network access to the RMI service exposed by the affected component.
  • Attack vector: network-based (AV:N), low attack complexity (AC:L).
  • Impact: high confidentiality impact and high integrity impact — unauthorized creation, deletion, or modification of data and full read access to data accessible through the application. No availability impact reported.

Affected software

  • Oracle Hyperion Financial Reporting, version 11.2.25.0.000

Severity

  • CVSS 3.1 Base Score: 9.1 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Mitigation and recommended actions

  • Immediate: Apply the Oracle Critical Patch Update that addresses this vulnerability for Oracle Hyperion Financial Reporting 11.2.25.0.000. Consult Oracle’s published security advisory for the specific patch identifier and apply it as soon as possible.
  • If immediate patching is not possible: Restrict network access to the RMI service used by Hyperion Financial Reporting (e.g., via firewall rules or network segmentation) so it is not reachable from untrusted networks, and monitor for unexpected RMI connections 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.
