CVE-2026-62575: Oracle Hyperion Information Disclosure

CVE-2026-62575 Overview

CVE-2026-62575 is an information disclosure vulnerability in the Oracle Hyperion Infrastructure Technology product, within the Installation and Configuration component. The affected supported version is 11.2.25.0.000. A low-privileged attacker with local logon access to the infrastructure where Oracle Hyperion Infrastructure Technology executes can exploit this flaw. Successful exploitation results in unauthorized access to critical data or complete access to all Oracle Hyperion Infrastructure Technology accessible data. The vulnerability is difficult to exploit and requires local access with valid credentials.

Critical Impact
Successful exploitation grants unauthorized read access to sensitive data managed by Oracle Hyperion Infrastructure Technology, exposing enterprise financial and planning information.

Technical Details for CVE-2026-62575

Vulnerability Analysis

The vulnerability resides in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. An attacker with valid local credentials on the host running the product can leverage flaws in how the component handles sensitive artifacts during installation and configuration operations. The impact scope covers confidentiality only, with no integrity or availability effects. Attack complexity is high, meaning the attacker must satisfy specific conditions outside their control to succeed. The exploit does not require user interaction, and the scope remains unchanged after compromise.

Root Cause

The root cause relates to improper handling of sensitive configuration data within the Installation and Configuration component. Local low-privileged users can access data that should remain restricted to administrative accounts. Oracle has not published detailed technical information about the specific weakness, and no CWE identifier has been assigned in the NVD entry.

Attack Vector

Exploitation requires local access (AV:L) to the server hosting Oracle Hyperion Infrastructure Technology. The attacker must hold a valid low-privileged account (PR:L) on the underlying operating system. No user interaction is required. The vulnerability cannot be exploited remotely over the network, which limits its reach to insiders or attackers who have already gained a foothold on the host. Refer to the Oracle Security Alert for vendor-published details.

Detection Methods for CVE-2026-62575

Indicators of Compromise

Unexpected access to Oracle Hyperion configuration files or installation directories by non-administrative accounts
Local logon events on Hyperion servers from accounts that do not typically interact with the platform
Anomalous read operations against Hyperion data stores or configuration repositories

Detection Strategies

Audit file access on Hyperion installation directories and configuration paths for reads by low-privileged users
Correlate local logon events with subsequent access to Hyperion binaries and data files
Monitor privileged process activity for unusual child processes spawned by low-privileged users

Monitoring Recommendations

Enable OS-level audit policies for file and object access on the Hyperion host
Forward Hyperion application and OS security logs to a centralized SIEM for correlation
Establish baselines for typical account behavior on Hyperion servers and alert on deviations

How to Mitigate CVE-2026-62575

Immediate Actions Required

Apply the Oracle Critical Patch Update from the August 2026 advisory to affected Hyperion Infrastructure Technology deployments
Restrict local logon rights on Hyperion servers to administrative personnel only
Review and reduce the number of accounts with any access to the Hyperion host operating system

Patch Information

Oracle addressed CVE-2026-62575 in its August 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert for patch identifiers, download instructions, and installation prerequisites specific to Hyperion Infrastructure Technology version 11.2.25.0.000.

Workarounds

Enforce least privilege on the Hyperion host by removing interactive logon rights for non-essential accounts
Segment Hyperion servers into restricted network zones with strict jump host controls
Apply file system permissions to configuration and installation directories that deny read access to non-administrative users

bash

# Configuration example: restrict interactive logon on Windows Hyperion host
# Use Local Security Policy or Group Policy
# Computer Configuration > Windows Settings > Security Settings >
#   Local Policies > User Rights Assignment > "Allow log on locally"
# Remove all non-administrative groups and add only:
#   - Administrators
#   - HyperionServiceAccounts (dedicated service group)
