MITRE ATT&CK
1 technique across 1 tactic: Impact The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires only network access to the Service Delivery Platform Messaging Enabler HTTP interface - per the CVSS vector AV:N/AC:L/PR:N/UI:N, no authentication, no privileges, and no user interaction are needed against affected versions 12.2.1.4.0 and 14.1.2.0.0. The concrete prerequisite is HTTP reachability of the messaging endpoint; the real-world limiting factor is deployment topology, since SDP Messaging Enablers are typically fielded inside carrier/operator networks rather than on the public Internet, so an attacker must first be able to route to that HTTP service. Impact is limited to availability (complete DOS) with no confidentiality or integrity consequence. |
| Impact | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H is internally consistent and points to a genuinely low-barrier attack: network reachable, low complexity, no privileges, no user interaction, with impact confined entirely to availability (A:H, C:N/I:N). Oracle's own 'easily exploitable' language reinforces the low-complexity assessment. However, the practical priority is tempered by the absence of any confidentiality or integrity impact - this is a service-outage bug, not a breach vector - and by the product's limited deployment footprint. No EPSS probability was provided, no public exploit code has been identified, and the CVE is not listed in CISA KEV, so there is no evidence of active or widespread exploitation; risk today is theoretical but easy to realize if an attacker can reach the SDP HTTP interface. Net priority: elevated for organizations that expose SDP messaging endpoints to untrusted networks, lower where the platform sits behind carrier-internal segmentation. |
| Exploit ScenarioDerived | An attacker with network reach to the SDP Messaging Enabler sends a specially crafted or malformed HTTP message request that the messaging path fails to handle, causing the platform to hang or crash and denying service to all downstream messaging consumers. Because no authentication, privileges, or user interaction are required and complexity is low, the request can be scripted and repeated to keep the service down. No public proof-of-concept has been identified at time of analysis. |

Alert meAnalysisAIv1 – Jul 22, 2026
Denial-of-service in Oracle Fusion Middleware Service Delivery Platform (Messaging Enabler component), versions 12.2.1.4.0 and 14.1.2.0.0, lets an unauthenticated remote attacker send crafted HTTP traffic that hangs or repeatedly crashes the service, producing a complete availability outage. Oracle rates it CVSS 3.1 7.5 with availability-only impact and flags it as easily exploitable. There is no public exploit identified at time of analysis and it is not on CISA KEV; no EPSS score was provided in the source data.
RemediationAI
Apply the fixes delivered in Oracle's July 2026 Critical Patch Update; patch is available per vendor advisory at https://www.oracle.com/security-alerts/cpujul2026.html, though the source data does not specify a discrete fixed build number, so confirm the exact patch level for your 12.2.1.4.0 or 14.1.2.0.0 deployment directly from that CPU. Because Oracle bundles SDP fixes into the quarterly CPU, prioritize scheduling that patch cycle. As compensating controls until patched, restrict network reachability of the Messaging Enabler HTTP interface to trusted carrier/management networks via firewall or ACL, place the endpoint behind a reverse proxy or WAF that can rate-limit and drop malformed messaging requests, and enable automatic service restart/health-check supervision so a triggered hang or crash self-recovers - noting that restart supervision only shortens outage duration and does not stop a determined attacker from repeatedly re-triggering the crash, and that tightening network exposure may disrupt legitimate messaging peers if their source ranges are not correctly allowlisted.

Technical ContextAI · show details
Service Delivery Platform (SDP) is an Oracle Fusion Middleware telecom-oriented platform that exposes messaging and communication services; the affected component is the Messaging Enabler, which handles inbound messaging/signaling over HTTP. Because the flaw is reachable pre-authentication over the network and results in a hang or repeatable crash rather than data disclosure or code execution, the root cause is most consistent with an uncontrolled resource consumption or unhandled-input parsing defect in the HTTP-facing messaging path (CWE-400/CWE-248 class). The CWE was reported as N/A by Oracle and NVD, so the precise weakness class is inferred from the availability-only CVSS profile, not confirmed. No CPE strings were supplied; affected products are identified only by Oracle version strings 12.2.1.4.0 and 14.1.2.0.0.

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 HTTP to compromise Service Delivery Platform. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Service Delivery Platform. CVSS 3.1 Base Score 7.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
Executive ViewAI
Oracle Fusion Middleware Messaging Enabler (versions 12.2.1.4.0 and 14.1.2.0.0) is vulnerable to remote denial-of-service attacks from unauthenticated users, resulting in complete message delivery service outage. Organizations using these versions face immediate operational disruption risk, with no vendor patch currently available. Urgent compensating controls and upgrade planning are required to protect business messaging continuity.
No vendor-released patch identified at time of analysis. Interim mitigations: restrict HTTP access via firewall to trusted networks only; implement rate limiting and connection throttling; deploy Web Application Firewall (WAF) rules to filter suspicious traffic patterns; enable service monitoring and alerting for crashes; evaluate component disabling if operationally feasible; plan urgent upgrade to patched versions.
