CVE-2026-83084 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. CVSS 3.1 Base Score 7.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/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 authorization bypass or insufficient access control mechanism within the HTTP interface of the Audience module, which fails to properly validate user privileges before processing requests. Consequently, individuals possessing only low-level privileged accounts can exploit this weakness to escalate their effective permissions beyond what is intended by system administrators. This type of flaw is commonly categorized under CWE-269, Improper Privilege Management, and aligns with the ATT&CK technique T1078, Valid Accounts, as it allows an attacker to leverage legitimate but insufficient credentials to gain unauthorized access to sensitive resources.
The operational impact of this vulnerability extends beyond the immediate boundaries of the Oracle Marketing application due to a scope change in how the compromise is evaluated. While the technical flaw is localized within the Audience component, successful exploitation can lead to lateral movement or data exfiltration that affects additional products within the broader E-Business Suite ecosystem. This interconnectedness means that a breach in one module can serve as an entry point for compromising other critical business functions hosted on the same infrastructure. The primary consequence of this exploit is a high-impact loss of confidentiality, with attackers able to access and extract unauthorized data from the system. In severe cases, particularly if combined with other vulnerabilities or misconfigurations, it may lead to complete access to all Oracle Marketing accessible data, exposing sensitive customer information, marketing strategies, and proprietary business intelligence to malicious actors.
From a technical perspective, the exploitability of this vulnerability is heightened by its network accessibility via HTTP and the low barrier to entry for attackers. The CVSS 3.1 base score of 7.7 reflects these factors, indicating that an attacker with local or network access who holds basic user privileges can achieve significant impact without requiring any user interaction such as clicking a malicious link. This ease of exploitation makes it particularly dangerous in environments where internal networks are not strictly segmented or where default credentials and weak password policies persist among lower-level users. The attack vector is classified as Network (AV:N) with Low Complexity (AC:L), meaning that automated tools can readily identify and exploit this weakness across the internet or within compromised local networks, provided the attacker has valid low-privileged accounts on the target system.
To mitigate this risk, organizations running affected versions of Oracle E-Business Suite must prioritize applying the latest security patches released by Oracle for the Audience component. It is critical to verify that all systems are updated beyond version 12.2.3 up to at least the most recent supported release where this specific flaw has been remediated. In addition to patching, implementing strict network segmentation can help limit the blast radius of a potential compromise, ensuring that even if an attacker gains access through HTTP, they cannot easily pivot to other critical systems within the E-Business Suite environment. Furthermore, enforcing multi-factor authentication and regularly auditing user privileges will reduce the likelihood of low-privileged accounts being used as footholds for such attacks. Security teams should also monitor logs for unusual data retrieval patterns or unauthorized API calls originating from standard user accounts, which may indicate an active exploitation attempt against this vulnerability.
