MITRE ATT&CK
1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | The attacker must have a low-privileged authenticated account within the Oracle E-Business Suite environment - standard employee or read-only EBS accounts satisfy this requirement. Network access to the EBS application server over HTTP is required; this is a standard condition for any EBS user. No user interaction from a victim is needed. The affected product must be running Oracle EBS version 12.2.3 through 12.2.15 with the Marketing Encyclopedia System component active. The 'Authentication Bypass' reporter tag raises the question of whether even the PR:L requirement can be circumvented - if so, the effective exploitation condition drops to unauthenticated network access, but this is not confirmed from available data. Exploitation is NOT limited to any specific OS platform or database configuration beyond the EBS version range. There is no requirement for a non-default configuration - MES Internal Operations is a standard EBS component. |
| Impact | The CVSS 3.1 score of 7.7 (High) is driven by network access vector, low attack complexity, low privilege requirement, no user interaction, scope change, and high confidentiality impact - a combination that accurately reflects the real-world severity. The scope change elevates the score meaningfully beyond what a contained confidentiality flaw would warrant. EPSS data was not provided in the source intelligence, so exploitation probability cannot be quantified. The vulnerability is not listed in the CISA KEV catalog and no POC has been identified, which moderates near-term exploitation urgency. However, Oracle E-Business Suite is widely deployed in large enterprises, and any authenticated user with a basic EBS account could potentially exploit this - meaning even a mid-sized municipal IT team in boleslawiec running an EBS deployment should treat this as an urgent patch cycle item given the low exploitation bar. The 'Authentication Bypass' tag introduces some ambiguity: if the PR:L prerequisite can itself be bypassed, the effective risk is higher than the CVSS vector reflects. This discrepancy between the tag and the vector should be verified against the full Oracle advisory. |
| Exploit ScenarioDerived | An attacker with a low-privileged Oracle EBS account - such as a standard employee user - sends crafted HTTP requests to the Internal Operations component of Oracle Marketing Encyclopedia System over the network. By exploiting the improper authorization flaw, the attacker reads sensitive business data across the MES application and potentially adjacent EBS modules due to the scope change. No public exploit code has been identified at time of analysis, but the low complexity and minimal prerequisites make independent exploitation development straightforward for a motivated attacker. |

Alert meAnalysisAIv1 – Aug 19, 2026
Unauthorized data disclosure in Oracle Marketing Encyclopedia System (E-Business Suite versions 12.2.3 through 12.2.15) allows a low-privileged, network-authenticated attacker to gain complete read access to all data accessible by the application component. The vulnerability carries a scope change, meaning successful exploitation can impact resources beyond the immediately compromised component. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog, though the tags attribute 'Authentication Bypass' suggesting the low-privilege barrier may be weaker in practice than the PR:L CVSS metric implies.
RemediationAI
Apply the Oracle Critical Patch Update (CPU) released in August 2026, available through the Oracle support portal referenced at https://www.oracle.com/security-alerts/cspuaug2026.html. The exact patched version number is not independently confirmed from the available data - administrators should consult the CPU advisory to identify the specific patch bundle applicable to their EBS release. As a compensating control while patching is scheduled, restrict network access to the Oracle MES Internal Operations endpoints using application-layer controls or network ACLs, limiting access to only users and hosts with a legitimate business need. Additionally, review and tighten EBS role assignments to minimize the number of accounts holding even low-level MES privileges, reducing the pool of potential exploiters. Note that network-layer restrictions may interfere with legitimate EBS workflows if MES is broadly used.

Technical ContextAI · show details
The affected component is the Internal Operations module of Oracle Marketing Encyclopedia System (MES), a document management and knowledge-sharing component of the Oracle E-Business Suite (EBS) platform. Oracle EBS is a large enterprise resource planning suite delivered over HTTP/HTTPS, and its internal components typically rely on Oracle's application-level authorization framework. The CWE is not specified by NVD, but the reporter tags include 'Authentication Bypass,' suggesting the root cause may involve improper authorization checks - a class of flaw (CWE-285 or CWE-863) where a low-privileged session can access resources or operations restricted to higher-privilege roles. The CVSS scope change (S:C) indicates the vulnerability crosses a security boundary, potentially allowing access to data in adjacent EBS modules or the underlying database layer beyond MES itself. Affected CPE corresponds to Oracle E-Business Suite versions 12.2.3 through 12.2.15.

DescriptionCVE.org
Vulnerability in the Oracle Marketing Encyclopedia System 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 HTTP to compromise Oracle Marketing Encyclopedia System. While the vulnerability is in Oracle Marketing Encyclopedia System, 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 Encyclopedia System 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).
Executive ViewAI
A HIGH-severity vulnerability in Oracle E-Business Suite Marketing Encyclopedia System (versions 12.2.3-12.2.15) allows authenticated users with low-privilege accounts to read all data accessible to the application, expanding access beyond intended scope. Organizations using these versions face elevated data breach risk from compromised credentials or malicious insiders. Immediate assessment and protective controls are critical to prevent unauthorized disclosure of sensitive business information.
Network segmentation limiting system connectivity to approved networks; restrictive access controls on low-privilege accounts scoped to minimum necessary data; comprehensive database audit logging and query logging with real-time alerting for access anomalies; regular access reviews and permission audits; enhanced monitoring of database activity for indicators of unauthorized data exfiltration.
