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 | Exploitation requires network reachability to the WebLogic T3 and/or IIOP listener of the Service Delivery Platform (Messaging Enabler component) and low-privilege authenticated access to the platform (CVSS PR:L) - it is not exploitable by a fully anonymous, unauthenticated attacker. No user interaction is required (UI:N) and attack complexity is low (AC:L). The practical limiting factors are: the attacker must already hold some valid low-privilege credential or foothold, and the T3/IIOP ports must be reachable from the attacker's position - deployments that firewall or connection-filter T3/IIOP to trusted management hosts substantially reduce exposure. Only Service Delivery Platform 12.2.1.4.0 and 14.1.2.0.0 are affected. |
| Impact | The signals point to a genuine high priority, though real-world reach is bounded by product prevalence. CVSS 3.1 is 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H): network reachable, low attack complexity, only low privileges required, no user interaction, full C/I/A impact, and a scope change that Oracle explicitly says 'may significantly impact additional products.' That scope change is what pushes it to near-maximum severity. However, exploitation is NOT fully unauthenticated - PR:L means the attacker must already hold some low-privilege access or a foothold, which is a meaningful limiting factor. EPSS is not provided in the input, so exploitation probability cannot be quantified. It is not in CISA KEV and no POC is referenced, so there is no evidence of active exploitation - this is a patch-now-on-severity case, not a fire-drill-on-active-exploitation case. Note a minor tension in the source data: the tag says 'Information Disclosure,' but the CVSS vector and description indicate full takeover (C:H/I:H/A:H), so the tag understates the actual impact - trust the vector over the tag. |
| Exploit ScenarioDerived | An attacker who has obtained low-privilege access to the environment (e.g., a limited application account or an internal foothold) sends crafted T3 or IIOP requests to the WebLogic-hosted Service Delivery Platform Messaging Enabler over the network. Because attack complexity is low and no user interaction is needed, they trigger the flaw to take over the SDP instance and, thanks to the scope change, pivot to impact additional integrated products. No public POC or exploit code is referenced in the source data at time of analysis. |

Alert meAnalysisAIv1 – Jul 22, 2026
Full system takeover in Oracle Service Delivery Platform (Fusion Middleware, Messaging Enabler component) versions 12.2.1.4.0 and 14.1.2.0.0 allows a low-privileged, network-authenticated attacker to compromise the platform via the WebLogic T3/IIOP protocols. The flaw carries a CVSS 3.1 score of 9.9 with a scope change, meaning successful exploitation impacts additional downstream products beyond the vulnerable component. Addressed in Oracle's July 2026 Critical Patch Update; no public exploit identified at time of analysis and it is not listed in CISA KEV.
RemediationAI
Apply the fixes in Oracle's July 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpujul2026.html) for Service Delivery Platform 12.2.1.4.0 and 14.1.2.0.0 - Patch available per vendor advisory, but no discrete fixed version string is published separately from the CPU bundle, so map your installed version to the corresponding CPU patch. Because the vector is WebLogic T3/IIOP, the most effective compensating control until patching is to restrict these protocols: use the WebLogic 'Connection Filter' (weblogic.security.net.ConnectionFilterImpl) to allow T3/T3S/IIOP only from known internal management hosts and deny it from general/untrusted networks, and firewall the WebLogic listen ports (default 7001/7002) so T3/IIOP is not internet-reachable - the trade-off is that legitimate remote EJB/JMS clients and inter-domain traffic using T3/IIOP must be explicitly allowlisted or they will break. Also tighten account privileges on the platform since exploitation requires only low privileges (PR:L), reducing the pool of accounts that could stage an attack. Do not rely on the workaround as a permanent fix - the CPU patch is the authoritative remediation.

Technical ContextAI · show details
Oracle Service Delivery Platform (SDP) is a telecom/communications middleware layer built on Oracle Fusion Middleware and WebLogic Server, used to expose and orchestrate messaging and network services; the affected 'Messaging Enabler' component handles message delivery integration. The exposed attack surface is WebLogic's T3 and IIOP remote protocols - proprietary RMI-style binary protocols used for remote EJB/JNDI invocation and inter-server communication, which have historically been a rich source of deserialization and remote-invocation vulnerabilities in the Oracle/WebLogic ecosystem. No CWE was assigned in the source data, so the precise root-cause class cannot be confirmed, but the combination of T3/IIOP as the vector plus a scope change is consistent with an unsafe remote-object/deserialization or authorization flaw that lets an authenticated principal escalate control of the server process and pivot to other integrated products.

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 low privileged attacker with network access via T3, IIOP to compromise Service Delivery Platform. While the vulnerability is in Service Delivery Platform, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Service Delivery Platform. CVSS 3.1 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
Executive ViewAI
A critical vulnerability in Oracle Service Delivery Platform's Messaging Enabler component (versions 12.2.1.4.0 and 14.1.2.0.0) enables complete system compromise through WebLogic protocols with low-privilege network access, affecting all systems running these versions. Organizations depending on these components for messaging and integration services face risk of service disruption, unauthorized data access, and potential impact to connected systems. Immediate identification of affected systems and implementation of containment measures are essential given the severity and broad exploitation surface.
Until vendor patch availability: restrict WebLogic T3/IIOP protocol network access through firewall rules and network segmentation; implement enhanced logging and real-time alerting for authentication attempts and privilege escalation events on affected systems; disable remote T3/IIOP access where operationally feasible; establish enhanced security monitoring for indicators of compromise including unusual database and file access patterns; maintain incident response readiness for potential active exploitation scenarios.
