CVE-2026-83304 in Business Intelligence Enterprise Edition
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics (component: Analytics Web General). Supported versions that are affected are 8.2.0.0.0, 12.2.1.4.0 and 26.01.0.0.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Business Intelligence Enterprise Edition. 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 unauthorized creation, deletion or modification access to critical data or all Oracle Business Intelligence Enterprise Edition accessible data as well as unauthorized access to critical data or complete access to all Oracle Business Intelligence Enterprise Edition accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Business Intelligence Enterprise Edition. CVSS 3.1 Base Score 8.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:L).

The identified vulnerability resides within the Analytics Web General component of Oracle Business Intelligence Enterprise Edition, a core part of the Oracle Analytics suite. This security flaw affects multiple supported versions including 8.2.0.0.0, 12.2.1.4.0, and 26.01.0.0.0. The nature of this vulnerability is characterized by its difficulty to exploit, which suggests that while it does not allow for trivial automated exploitation via simple script kiddie tools, it remains a significant threat due to the high privilege level granted upon successful compromise. An unauthenticated attacker with network access via HTTP can leverage this flaw to gain unauthorized control over the system. The presence of an attack vector through HTTP indicates that the vulnerability is accessible over standard web protocols, potentially allowing remote exploitation without requiring user interaction or prior authentication credentials.
The technical impact of exploiting this vulnerability extends beyond the immediate boundaries of Oracle Business Intelligence Enterprise Edition due to a scope change in the security assessment. This means that while the flaw originates within the BI platform, successful exploitation can lead to lateral movement or compromise of additional connected products and underlying infrastructure components. The primary consequences involve unauthorized creation, deletion, or modification of critical data stored within the system. Furthermore, an attacker gains complete access to all Oracle Business Intelligence Enterprise Edition accessible data, effectively breaking confidentiality guarantees for sensitive organizational information. This level of access allows adversaries to exfiltrate proprietary business intelligence reports, customer datasets, and strategic analytics that are central to enterprise decision-making processes.
In addition to compromising data integrity and confidentiality, the vulnerability also impacts system availability by enabling unauthorized ability to cause a partial denial of service against Oracle Business Intelligence Enterprise Edition. While this does not result in a complete shutdown of services, it can degrade performance or render specific analytical functions unavailable to legitimate users, thereby disrupting business operations that rely on real-time or scheduled reporting capabilities. The combination of these impacts results in a CVSS 3.1 Base Score of 8.9, classified as High severity. This score reflects the high impact on confidentiality and integrity alongside a lower but present impact on availability. The specific vector string (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:L) highlights that although the attack complexity is high and requires no user interface interaction, the lack of required privileges for the attacker combined with the scope change significantly elevates the risk profile.
From a classification perspective, this vulnerability aligns with CWE-287 Improper Authentication as it allows unauthenticated access to sensitive resources. The ability to modify data corresponds to CWE-362 Concurrent Execution using Shared Resource with Improper Synchronization or more broadly CWE-94 Code Injection if the mechanism involves injecting commands through web inputs. The potential for denial of service relates to CWE-787 Out-of-bounds Write or resource exhaustion techniques found in CWE-400. In terms of offensive security frameworks, this vulnerability facilitates actions consistent with MITRE ATT&CK technique T1190 Exploit Public-Facing Application and potentially T1530 Data from Cloud Storage if the BI system integrates with external data lakes. The scope change aspect suggests potential for lateral movement techniques such as T1210 Exploitation of Remote Services to pivot into adjacent systems within the enterprise network.
Mitigation strategies must prioritize immediate patching by applying the latest security updates provided by Oracle for all affected versions listed, specifically 8.2.0.0.0, 12.2.1.4.0, and 26.01.0.0.0. Organizations should verify their deployment configurations to ensure that no unnecessary HTTP exposure exists if HTTPS is available and properly configured with strong cipher suites. Implementing strict network segmentation can help isolate the Oracle Business Intelligence servers from less trusted networks, reducing the attack surface for unauthenticated remote attackers. Additionally, deploying Web Application Firewalls with rules tailored to detect exploitation attempts against known BI vulnerabilities can provide an additional layer of defense. Continuous monitoring of access logs for anomalous patterns indicative of data exfiltration or unauthorized modifications is essential for early detection and response in environments where patching might be delayed due to operational constraints.
