DescriptionCVE.org

Vulnerability in the Service Delivery Platform product of Oracle Fusion Middleware (component: Messaging Enabler). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via SOAP to compromise Service Delivery Platform. Successful attacks of this vulnerability can result in takeover of Service Delivery Platform. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

AnalysisAI

Unauthenticated attackers with network access to the SOAP interface of Oracle Service Delivery Platform (SDP) versions 12.2.1.4.0 and 14.1.2.0.0 can bypass authentication and achieve full takeover of the product, per CWE-287 and a CVSS 3.1 base score of 9.8. The flaw is remotely exploitable without privileges or user interaction (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), and no public exploit code or active exploitation (CISA KEV) has been identified at time of analysis. …

Vulnerability AssessmentAI

Exploitation No special conditions - remote unauthenticated exploitation is possible against the SOAP interface of Oracle Service Delivery Platform (Messaging Enabler) versions 12.2.1.4.0 and 14.1.2.0.0, per AV:N/AC:L/PR:N/UI:N. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuinely high-priority vulnerability by base-severity signals: the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, 9.8) describes a remote, unauthenticated, low-complexity SOAP attack yielding full compromise (complete confidentiality, integrity and availability impact), consistent with CWE-287 (authentication bypass) and the vendor's own 'takeover' wording. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Apply the patch from Oracle when released; the available data does not specify an exact fix version, so monitor the Oracle security advisory at https://www.oracle.com/security-alerts/cspusep2026.html for patch availability and version details. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Because no public exploit identified at time of analysis, within 24 hours inventory all Oracle Service Delivery Platform deployments and confirm whether versions 12.2.1.4.0 or 14.1.2.0.0 are running, then restrict network access to the SOAP interface via firewall rules, security groups, or access control lists to trusted management networks only; disable SOAP endpoints if not business-essential and enable verbose logging for authentication and SOAP traffic. …
