Vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion (component: Installation and Configuration). The supported version that is affected is 11.2.25.0.000. Difficult to exploit vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Oracle Hyperion Infrastructure Technology executes to compromise Oracle Hyperion Infrastructure Technology. Successful attacks of this vulnerability can result in takeover of Oracle Hyperion Infrastructure Technology. CVSS 3.1 Base Score 7.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
AnalysisAI
Full system takeover of Oracle Hyperion Infrastructure Technology 11.2.25.0.000 is achievable by an unauthenticated attacker positioned on the same physical network segment as the affected host, exploiting a flaw in the Installation and Configuration component. The CVSS vector confirms adjacent-network vector (AV:A) with high attack complexity (AC:H), meaning exploitation requires specific conditions but no credentials. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be physically or logically positioned on the same network segment (broadcast domain) as the hardware running Oracle Hyperion Infrastructure Technology version 11.2.25.0.000 - this is the AV:A constraint and is the primary limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.5 with vector AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H reflects a balanced but meaningful risk profile. … 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 Oracle's Critical Security Patch Update for August 2026, available at https://www.oracle.com/security-alerts/cspuaug2026.html, which addresses this vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all systems running Oracle Hyperion Infrastructure Technology 11.2.25.0.000 and document their network segment and access controls; simultaneously escalate to Oracle support with CVE-2026-62545 for patch timeline confirmation. …
