CVE-2026-83323 in Business Intelligence Enterprise Edition
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics (component: Platform Security). The supported version that is affected is 26.01.0.0.0. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Business Intelligence Enterprise Edition executes to compromise Oracle Business Intelligence Enterprise Edition. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Business Intelligence Enterprise Edition, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Business Intelligence Enterprise Edition. CVSS 3.1 Base Score 7.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H).

Analysis

The identified vulnerability resides within the Platform Security component of Oracle Business Intelligence Enterprise Edition, specifically affecting version 26.01.0.0.0 and potentially other supported releases within the Oracle Analytics suite. This flaw represents a significant security risk due to its potential for privilege escalation and system compromise. The core technical issue involves a mechanism that allows an attacker with low privileges on the underlying infrastructure where the application executes to manipulate critical security controls or bypass authentication checks. Although the vulnerability is technically located in the Business Intelligence platform, the nature of enterprise integration means that compromising this component can lead to a broader scope change, impacting additional products and services connected to the analytics environment.
Exploitation of this vulnerability requires specific conditions that distinguish it from remote code execution flaws accessible over a network. The attacker must have low-privileged logon access to the infrastructure hosting Oracle Business Intelligence Enterprise Edition. This implies physical or local administrative access is not required, but some form of authenticated entry point into the system environment is necessary. Furthermore, successful exploitation demands human interaction from a user other than the attacker. This social engineering aspect suggests that the vulnerability may involve deceptive prompts, malicious file execution triggered by another user, or phishing-based interactions where an unsuspecting employee inadvertently triggers the exploit chain. The requirement for UI involvement significantly raises the barrier to entry for automated attacks but does not eliminate the risk in environments with poor endpoint hygiene or lax security awareness training.
The operational impact of a successful attack is severe, resulting in complete takeover of Oracle Business Intelligence Enterprise Edition. With full control over the application layer, an attacker can manipulate data integrity by altering reports and dashboards to mislead decision-makers. They can exfiltrate sensitive corporate intelligence stored within the analytics platform, leading to significant confidentiality breaches. Additionally, the ability to disrupt services impacts availability, potentially halting critical business operations that rely on real-time analytics. The CVSS 3.1 base score of 7.5 reflects these high-impact outcomes across confidentiality, integrity, and availability vectors. The vector string AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H confirms the local attack vector, high complexity, low privilege requirement, required user interaction, scope change to other components, and high impact on all security properties.
From a classification perspective, this vulnerability aligns with CWE-269 Improper Privilege Management or potentially CWE-787 Out-of-bounds Write if memory corruption is involved in the takeover mechanism. It also maps to MITRE ATT&CK techniques such as T1053 Scheduled Task/Job which may be used for persistence after initial access, and T1046 Network Service Discovery if the attacker uses the compromised BI server to map further network assets. The scope change aspect highlights the risk of lateral movement within integrated enterprise ecosystems where a compromise in one module can cascade into others due to shared credentials or trust relationships.
Mitigation strategies must address both technical controls and organizational processes. Oracle should be consulted for available patches or workarounds that restrict access to the Platform Security component. Administrators should enforce strict least-privilege principles, ensuring that users with logon access to the infrastructure do not have unnecessary permissions within the BI application layer. Network segmentation is critical; the BI servers should reside in isolated zones with restricted inbound and outbound traffic to limit the blast radius of any potential compromise. Given the requirement for human interaction, comprehensive security awareness training is essential to educate employees on recognizing social engineering attempts that could trigger this vulnerability. Regular audits of user access rights and monitoring for anomalous activities within the BI platform can help detect exploitation attempts early. Finally, maintaining up-to-date backups ensures rapid recovery in case a successful takeover occurs, minimizing downtime and data loss.
