CVE-2026-83162 in Application Object Library
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Application Object Library product of Oracle E-Business Suite (component: Core). Supported versions that are affected are 12.2.3-12.2.15. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Oracle Application Object Library. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Application Object Library accessible data as well as unauthorized access to critical data or complete access to all Oracle Application Object Library accessible data. CVSS 3.1 Base Score 7.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N).

The identified vulnerability resides within the Core component of Oracle Application Object Library, a critical module in the Oracle E-Business Suite architecture that manages fundamental application data and business logic. This security flaw affects supported software versions ranging from 12.2.3 through 12.2.15. The nature of this defect is characterized by its difficulty to exploit, which suggests that while the underlying technical mechanism may be complex or require specific conditions to trigger successfully, it does not rely on user interaction or high-privilege credentials for initial access. This classification indicates a vulnerability where an attacker must possess significant skill or utilize sophisticated techniques to leverage the flaw effectively against a properly configured system.
From a network perspective, this vulnerability is remotely exploitable without authentication. An unauthenticated attacker with network connectivity via HTTPS can target the affected service. The use of HTTPS implies that while transport encryption is present, it does not mitigate the underlying application-layer logic error or configuration weakness within the Oracle Application Object Library itself. This allows external adversaries to initiate attacks over standard web ports, bypassing traditional perimeter defenses that rely solely on authentication requirements for entry points.
The operational impact of a successful exploitation is severe, primarily affecting data confidentiality and integrity while leaving availability largely intact according to the provided metrics. A compromised system results in unauthorized creation, deletion, or modification of critical data stored within the Oracle Application Object Library. Furthermore, it grants attackers complete access to all data accessible by this component. This level of access effectively breaks the isolation boundaries between different modules of the E-Business Suite, potentially exposing sensitive financial records, customer information, and proprietary business processes to malicious actors who can alter or exfiltrate this data at will.
In terms of industry-standard classification frameworks, this vulnerability aligns with CWE-287, which covers Improper Authentication, as it allows unauthenticated access to critical functions. It also relates closely to CWE-601, URL Redirection to Untrusted Site, if the exploitation involves redirecting users or data flows, though the primary concern here is unauthorized data manipulation and access. The attack vector maps directly to MITRE ATT&CK technique T1190, Exploit Public-Facing Application, as it targets a web-accessible component of an enterprise suite. Additionally, the ability to modify critical data corresponds to T1565, Data Manipulation, where attackers alter stored information to achieve their objectives or disrupt business operations.
The CVSS 3.1 base score of 7.4 reflects these high-impact consequences on confidentiality and integrity. The vector string (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N) confirms that while the attack complexity is high, requiring skilled exploitation efforts, the lack of required privileges and user interaction makes it a significant threat to organizations relying on these specific versions of Oracle E-Business Suite. The scope remains unchanged (S:U), meaning the impact is generally confined to the affected component's data context rather than escalating to broader system compromise immediately, but within that context, the damage potential is maximal for both reading and writing sensitive information.
Mitigation strategies must prioritize immediate patching if available from Oracle through official support channels. Organizations should apply the latest security patches or updates provided by Oracle for their specific version of E-Business Suite to address this flaw in the Core component. In environments where immediate patching is not feasible due to operational constraints, network segmentation and strict access control lists (ACLs) restricting HTTPS traffic from untrusted networks to the servers hosting the affected components are essential defensive measures. Web Application Firewalls should be configured with rulesets capable of detecting anomalous request patterns associated with this specific vulnerability's exploitation method. Continuous monitoring for unusual data modification activities within the Oracle database and application logs is also recommended to detect potential compromise attempts early.
