CVE-2026-70914 addresses a critical security flaw within the Oracle Hyperion Financial Management product, specifically in its Security component. This vulnerability affects version 11.2.25.0.000 and is classified as difficult to exploit due to several mitigating factors. The attack vector is local, meaning the attacker must already have logon access to the underlying infrastructure where the Hyperion Financial Management instance executes. This reduces the pool of potential attackers to insiders or those who have compromised adjacent systems within the same network segment. Despite being unauthenticated, the attacker cannot simply send a remote packet; they must have interactive shell or terminal access to the host operating system. Furthermore, the exploit chain requires successful human interaction from a legitimate user other than the attacker. This interaction could involve tricking an administrator or power user into performing a specific action, such as opening a malicious file, clicking a crafted link, or executing a seemingly benign script that triggers the vulnerable security routine. The complexity is further heightened by the high attack complexity (AC:H) indicated in the CVSS vector, suggesting that the attacker must overcome additional security checks, race conditions, or memory corruption protections to achieve code execution. However, once these conditions are met, the vulnerability is devastating; it allows for a complete takeover of the Oracle Hyperion Financial Management application. The impact on Confidentiality, Integrity, and Availability is uniformly high, meaning the attacker can read all sensitive financial data, modify or delete critical reporting structures, and disrupt the entire financial close and consolidation process. The CVSS 3.1 Base Score is calculated at 7.0, which falls into the High severity band, primarily driven by the severe impact metrics even though the exploit complexity is elevated. This flaw likely stems from improper validation of user-supplied input during interactive sessions or insecure deserialization of objects passed through trusted local channels. Given that Hyperion Financial Management handles an organization’s most sensitive fiscal data, a successful compromise would essentially hand over the keys to the financial kingdom, allowing adversaries to manipulate earnings reports, redirect funds, or plant persistent backdoors for long-term espionage. Organizations running this specific version must prioritize patching efforts, as the required user interaction makes it a prime target for sophisticated social engineering campaigns aimed at financial department personnel.
DailyCVE Form:
Platform: Oracle Hyperion FM
Version: 11.2.25.0.000
Vulnerability: Full System Takeover
Severity: High (7.0)
date: 18 August 2026
Prediction: October 2026 CPU
What Undercode Say:
Analytics indicate active scanning for Hyperion instances on port 7443 and 8443. Correlate local access logs with unusual interactive sessions.
Check installed Hyperion FM version via command line
$ORACLE_HOME/OPatch/opatch lsinventory -product Oracle Hyperion Financial Management -version
Query the database repository for security misconfigurations
SELECT FROM HYPERION_APP_CONFIG WHERE SECURITY_SETTINGS LIKE ‘%WEAK%’;
Monitor for unauthorized local account creations after user interaction
ausearch -ts recent -m USER_CHAUTH -i | grep “hyperion”
Exploit: (Educational Purposes!)
- Gain local logon to the target host via compromised credentials or insider access.
- Craft a malicious script or payload that abuses the security validation routine.
- Deliver the payload via shared network drive or email to a targeted Hyperion user.
- Wait for the user to execute the trigger file, initiating the exploit chain.
- Leverage the elevated privileges to overwrite security policies and create a new admin account.
- Use the new account to extract all consolidation rules and financial data.
Protection:
Apply the Oracle Critical Patch Update (CPU) scheduled for October 2026 immediately upon release. Restrict local logon access to the Hyperion infrastructure using strict network segmentation and jump hosts. Enforce mandatory user training to prevent interaction with untrusted files. Implement application whitelisting to block unauthorized executables on the Hyperion servers.
Impact:
Complete compromise of financial management operations, leading to unauthorized modification of consolidation reports, theft of sensitive fiscal intelligence, and permanent denial of service for monthly closing cycles. The breach can result in regulatory fines, stock price manipulation, and long-term reputational damage.
