CVE-2026-83083 in Marketing
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Marketing product of Oracle E-Business Suite (component: Audience). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Marketing. While the vulnerability is in Oracle Marketing, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Marketing accessible data as well as unauthorized update, insert or delete access to some of Oracle Marketing accessible data. CVSS 3.1 Base Score 8.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N).

The identified vulnerability resides within the Audience component of Oracle Marketing, a module integrated into Oracle E-Business Suite versions ranging from 12.2.3 through 12.2.15. This security flaw represents a significant risk to organizations relying on these specific releases for their customer relationship management and marketing automation operations. The core issue stems from an improper access control mechanism that fails to adequately restrict data retrieval and modification permissions based on user roles or privileges. Consequently, the vulnerability allows any authenticated attacker with low-level privileges to interact directly with sensitive backend systems via standard HTTP protocols without requiring complex exploitation techniques or social engineering vectors such as user interaction.
From a technical perspective, this flaw is classified under CWE-269, which denotes Improper Privilege Management, and aligns with MITRE ATT&CK technique T1078, Valid Accounts, specifically the use of default accounts or low-privileged legitimate credentials to gain unauthorized access. The attacker leverages network connectivity over HTTP to send crafted requests that bypass intended authorization checks. Because the vulnerability is embedded within a widely used enterprise suite, the scope change associated with this flaw means that compromising Oracle Marketing can lead to lateral movement and impact other interconnected products within the E-Business Suite environment. This expands the blast radius of an initial compromise far beyond the marketing module itself, potentially exposing financial records, human resources data, or supply chain information stored in adjacent modules.
The operational impact of exploiting this vulnerability is severe, characterized by high confidentiality loss and moderate integrity violation as reflected in a CVSS 3.1 Base Score of 8.5. Successful exploitation enables an attacker to perform unauthorized access to critical business data, effectively stripping the organization of its ability to maintain privacy compliance with regulations such as GDPR or CCPA. Furthermore, the vulnerability grants the ability to update, insert, or delete accessible data within Oracle Marketing. This integrity impact allows malicious actors to alter customer profiles, manipulate campaign metrics, or inject fraudulent transactions, which can lead to significant financial loss and reputational damage. The absence of availability impact indicates that while data is compromised, system uptime may remain unaffected initially, but the long-term operational disruption from remediation efforts will be substantial.
To mitigate this risk, organizations must prioritize applying the latest security patches provided by Oracle for all supported versions within the 12.2.x range. Immediate implementation of these updates is critical to close the privilege escalation gap. In environments where patching cannot occur immediately due to operational constraints, network segmentation strategies should be employed to restrict HTTP access to the affected components from untrusted networks or low-privileged user segments. Additionally, implementing strict Web Application Firewall rules can help detect and block anomalous request patterns associated with this exploitation vector. Regular auditing of user privileges within Oracle E-Business Suite is also recommended to ensure that no accounts possess excessive permissions beyond their required job functions, thereby reducing the attack surface available to potential intruders who have obtained low-level credentials.
