AnalysisAIv1 – Sep 15, 2026

Unauthenticated denial of service combined with unauthorized data modification in the Oracle Mobile Application Server (MWA Terminal Server) component of Oracle E-Business Suite 12.2.3 through 12.2.15. A remote attacker with HTTP access can send crafted requests that hang or repeatedly crash the MWA service while also inserting, updating, or deleting some MWA-accessible data, but the attack requires a victim — not the attacker — to perform some interaction (UI:R), and Oracle's scope-change rating indicates effects can spill over to related products. Oracle rates this 8.2 High; no public exploit code and no CISA KEV listing were identified in the supplied intelligence, and no EPSS score was provided.

DescriptionCVE.org

Vulnerability in the Oracle Mobile Application Server product of Oracle E-Business Suite (component: MWA Terminal Server). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Mobile Application Server. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Mobile Application Server, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Mobile Application Server as well as unauthorized update, insert or delete access to some of Oracle Mobile Application Server accessible data. CVSS 3.1 Base Score 8.2 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:H).

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
