Which versions of Service Delivery Platform are affected by EUVD-2026-46837?

Oracle Communications Service Delivery Platform (Messaging Enabler) in Oracle Fusion Middleware versions 12.2.1.4.0 and 14.1.2.0.0 contains a critical flaw allowing remote unauthenticated attackers…

How to fix or mitigate EUVD-2026-46837?

Within 24 hours: Conduct a definitive inventory of all systems running affected Oracle Fusion Middleware versions (12.2.1.4.0 and 14.1.2.0.0) with the Messaging Enabler component, and assess network accessibility of T3 and IIOP protocol ports. Within 7 days: Implement mandatory network segmentation to restrict T3 and IIOP protocol access to only authorized internal networks; disable these protocols at the perimeter if business operations permit; deploy enhanced logging on all Messaging Enabler instances for attack surface monitoring. Within 30 days: Establish a formal upgrade path to versions beyond 14.1.2.0.0 (per Oracle guidance on remediated versions) and develop an expedited migration timeline; maintain continuous monitoring of Oracle security advisories for patch availability and coordinate with Oracle support on interim fixes if available.

CRITICAL 9.8

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 T3, IIOP 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

Full compromise of Oracle Communications Service Delivery Platform (Messaging Enabler component) in Oracle Fusion Middleware is achievable by a remote unauthenticated attacker over the T3 and IIOP protocols. Affecting versions 12.2.1.4.0 and 14.1.2.0.0, successful exploitation results in complete takeover of the platform with high confidentiality, integrity, and availability impact (CVSS 9.8). No public exploit has been identified at time of analysis, and it is not listed in CISA KEV, but the network-reachable, no-privilege attack profile makes it a high-priority patch.

Technical ContextAI

Service Delivery Platform is an Oracle Communications middleware product built on the Oracle WebLogic Server stack, and the affected surface is the T3 (WebLogic's proprietary RMI transport) and IIOP (CORBA-based) remote invocation protocols. These protocols carry serialized Java objects, and the WebLogic ecosystem has a long history of unsafe deserialization gadget chains reachable pre-authentication over exactly these ports (default 7001). The Messaging Enabler component is the affected module. No CWE was assigned in the input, but the T3/IIOP attack vector combined with unauthenticated remote code-level compromise is consistent with the Java deserialization (CWE-502) class that historically drives WebLogic 'takeover' advisories; this classification is inferred, not vendor-confirmed.

RemediationAI

Apply the fixes from the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html); no discrete fixed version string was published in the input beyond the CPU bundle, so treat this as 'Patch available per vendor advisory' and apply the CPU patch corresponding to your 12.2.1.4.0 or 14.1.2.0.0 deployment. Because the attack traverses T3 and IIOP, the primary compensating control until patching is to restrict those protocols: configure WebLogic connection filters (weblogic.security.net.ConnectionFilterImpl) to allow T3/T3s/IIOP only from trusted management hosts, or disable IIOP on managed servers where it is not required - note this can break legacy RMI/CORBA clients and inter-domain calls that rely on those transports. Additionally, firewall the administrative listen port (default 7001) so it is not exposed to untrusted networks. These controls reduce reachability but are not a substitute for the CPU patch.
