Analysis
by VulDB Data Team • 08/19/2026
The identified vulnerability resides within the Access and security component of Oracle Hyperion Data Relationship Management version 11.2.25.0.000, representing a critical flaw in the application's authentication or authorization logic. This defect allows for an easily exploitable attack vector that requires high-privileged access to execute effectively. The attacker must possess network connectivity via HTTPS, indicating that the vulnerability is remotely accessible over standard web protocols without requiring user interaction. Despite the requirement for initial high privileges, the ease of exploitation and the resulting impact classify this as a severe security risk within enterprise environments where such administrative credentials may be compromised through other means or social engineering tactics.
The technical nature of this flaw leads to a complete compromise of the Oracle Hyperion Data Relationship Management system upon successful exploitation. The primary consequence is full takeover of the application, which grants the attacker unrestricted control over the platform's functionalities and data stores. This level of access enables malicious actors to read, modify, or delete sensitive financial data managed by the DRM module. Furthermore, because Oracle Hyperion products are often integrated into broader enterprise resource planning ecosystems, this vulnerability exhibits a scope change characteristic where compromising one product significantly impacts additional connected systems. The attacker can leverage the compromised instance as a pivot point to launch further attacks against adjacent services and databases within the organization's infrastructure.
From an impact perspective, the vulnerability affects all three pillars of information security: confidentiality, integrity, and availability, resulting in a CVSS 3.1 Base Score of 9.1. The high score reflects the critical nature of losing control over financial data management tools. Unauthorized access compromises confidentiality by exposing proprietary financial models and reports. Integrity is undermined as attackers can alter transactional records or configuration settings without detection. Availability is impacted if the attacker chooses to disrupt service, lock out legitimate users, or deploy ransomware via the elevated privileges obtained through this flaw. The vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H confirms that while privilege requirements are high, the attack complexity is low and scope changes to other products amplify the overall risk profile significantly.
This vulnerability aligns with Common Weakness Enumeration categories such as CWE-269 Improper Privilege Management or CWE-732 Incorrect Permission Assignment for Critical Resource, depending on whether the flaw involves privilege escalation during authentication or improper access control checks post-authentication. In terms of MITRE ATT&CK mapping, this scenario corresponds to techniques involving Initial Access via valid accounts and subsequent Lateral Movement due to the scope change affecting additional products. The ability to take over an administrative interface facilitates Persistence through backdoor creation and Credential Dumping if underlying database credentials are accessible from within the compromised application context.
Mitigation strategies must prioritize immediate patching of Oracle Hyperion Data Relationship Management to version 11.2.25.0.001 or later, where this specific access control flaw has been addressed by the vendor. Organizations should also implement strict network segmentation to isolate critical financial applications from general corporate networks, thereby limiting the attack surface available via HTTPS. Enforcing multi-factor authentication for all administrative accounts adds a layer of defense that can prevent attackers who have obtained high-privileged credentials from exploiting this vulnerability. Additionally, deploying Web Application Firewalls with rules tailored to detect anomalous behavior in the access and security modules can help identify and block exploitation attempts before they result in system takeover. Regular audits of user permissions and review of administrative logs are essential for detecting any unauthorized changes or suspicious activities that may indicate a successful compromise prior to patching.
