Vulnerability AssessmentAI
| Exploitation | The only prerequisite is network HTTP access to the Oracle Hyperion Data Relationship Management web tier of version 11.2.25.0.000 - no authentication, no privileges, and no user interaction are required (AV:N/AC:L/PR:N/UI:N), consistent with the vendor's 'easily exploitable' and 'Authentication Bypass' characterization. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All signals point to a genuine high priority rather than an inflated high-CVSS-but-low-risk issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the fix from Oracle's Critical Patch Update of August 2026 (https://www.oracle.com/security-alerts/cspuaug2026.html); the input data does not specify an exact patched build number, so patch available per vendor advisory - consult that CPU page for the precise patch level for Hyperion DRM 11.2.25.0.000 and do not deploy an invented version number. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: identify and inventory all systems running Oracle Hyperion DRM 11.2.25.0.000; isolate them from untrusted networks or shut down non-critical instances immediately. …
