CVE-2026-83123 in Report Manager
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Report Manager product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTPS to compromise Oracle Report Manager. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Report Manager accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Report Manager. CVSS 3.1 Base Score 7.1 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L).

The identified vulnerability resides within the Oracle Report Manager component of Oracle E-Business Suite, specifically affecting internal operations across supported versions ranging from 12.2.3 to 12.2.15. This security flaw is classified as an Internal Operations weakness, indicating that the defect lies in how the application handles its own administrative or backend processes rather than a direct external interface failure. The vulnerability allows for unauthorized access and disruption by leveraging flaws in the internal logic of the Report Manager service. Because this component is integral to generating and delivering reports within the enterprise suite, compromising it can have significant repercussions on data integrity and system availability.
The technical nature of this flaw permits exploitation by an attacker with low privileges who possesses network access via HTTPS. This means that a user account with minimal initial permissions can leverage specific inputs or requests directed at the Report Manager interface to trigger the vulnerability. The attack vector is remote, requiring no physical proximity or local shell access, and does not rely on social engineering as it requires no user interaction beyond the initial authenticated connection. The low complexity of exploitation suggests that standard automated tools could potentially be used to exploit this weakness once valid credentials are obtained through other means such as credential stuffing or phishing attacks against lower-level accounts.
Successful exploitation results in two primary impacts: unauthorized access to critical data and a partial denial of service condition. In terms of confidentiality, the attacker gains the ability to read sensitive information stored within Oracle Report Manager that they would not normally be permitted to view. This could include financial reports, customer records, or proprietary business intelligence data depending on what is configured in the E-Business Suite environment. The availability impact manifests as a partial denial of service, where the functionality of Oracle Report Manager is degraded or halted for legitimate users. While it may not cause a complete system crash, the inability to generate or retrieve reports can disrupt critical business workflows that rely on timely data delivery.
From an industry standards perspective, this vulnerability aligns with CWE-269 Improper Privilege Management and potentially CWE-400 Uncontrolled Resource Consumption if the denial of service is caused by resource exhaustion. In terms of offensive security frameworks, the attack pattern corresponds to MITRE ATT&CK techniques related to Initial Access via Valid Accounts and Impact via Service Disruption or Data Exfiltration. The CVSS 3.1 base score of 7.1 reflects a High severity rating due to the combination of network accessibility, low privilege requirements, and significant impacts on both confidentiality and availability.
Mitigation strategies should prioritize immediate patching by applying the latest Oracle E-Business Suite release update that addresses this specific vulnerability in the Report Manager component. Organizations must ensure their systems are updated from version 12.2.3 through 12.2.15 to a patched version where these internal operation flaws have been resolved. In addition to patching, implementing strict network segmentation can limit exposure by ensuring that only authorized application servers and management consoles can communicate with the Report Manager service over HTTPS. Access control policies should also be reviewed to enforce the principle of least privilege, minimizing the number of users who hold even low-level access rights to E-Business Suite components. Continuous monitoring for anomalous activity within the report generation logs can help detect potential exploitation attempts early before significant data loss or operational disruption occurs.
