Vulnerability AssessmentAI
| Exploitation | The prerequisite is HTTP network access to an exposed Oracle Hyperion Infrastructure Technology 11.2.25.0.000 instance with the Common Events component reachable - no authentication, no privileges, and no user interaction are required (AV:N/AC:L/PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All CVSS signals point to maximum severity: AV:N (network), AC:L (low complexity), PR:N (unauthenticated), UI:N (no interaction), and C:H/I:H/A:H produce a 9.8 base score, indicating a reliable, low-effort path to full compromise. … 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 fixes delivered in the Oracle August 2026 Critical Patch Update (Patch available per vendor advisory) referenced at https://www.oracle.com/security-alerts/cspuaug2026.html; Oracle does not publish a separate fixed build string in this data, so consult the CPU matrix for the exact patch corresponding to 11.2.25.0.000. … Detailed patch versions, workarounds, and compensating controls in full report. |
