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 | No special conditions - remote unauthenticated exploitation against supported configurations of Oracle Coherence, requiring only HTTP network reachability to a Coherence node's Core component (CVSS AV:N/AC:L/PR:N/UI:N). The exploitation is limited by network exposure: the attacker must be able to reach the Coherence HTTP/cluster interface, so instances confined to trusted internal segments or firewalled off are correspondingly harder to reach. Affected scope is bounded to Coherence versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0; no specific non-default feature toggle is named as a precondition in the vendor description. |
| Impact | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, 9.8 Critical) signals the worst realistic profile: network-reachable, low complexity, no privileges, no user interaction, and total impact to confidentiality, integrity, and availability. Oracle's own language ('easily exploitable', 'unauthenticated attacker', 'takeover') reinforces the vector rather than conflicting with it. No EPSS score, SSVC decision, POC, or KEV entry was supplied, so exploitation probability cannot be quantified from the data - this is currently a severity-driven priority rather than a confirmed in-the-wild threat. Note a minor inconsistency: the vendor tag labels this 'Information Disclosure' while the CVSS and description indicate full takeover; treat the CVSS/description as authoritative and the tag as understated. Given unauthenticated network exploitability of an enterprise middleware component, defenders should treat this as high priority regardless of the missing EPSS/KEV signals. |
| Exploit ScenarioDerived | An attacker who can reach a Coherence node's HTTP-facing interface sends a crafted request to the Core component and, without any credentials or user interaction, gains full control over the Coherence instance. Because the vulnerability is easily exploitable and unauthenticated, an internet-exposed or lateral-network-reachable Coherence deployment could be taken over in a single automated request. No public proof-of-concept has been identified at time of analysis, but the low attack complexity makes reliable exploitation likely once details or tooling emerge. |

Alert meAnalysisAIv1 – Jul 21, 2026
Remote unauthenticated takeover in Oracle Coherence (Oracle Fusion Middleware, Core component) allows an attacker with only HTTP network access to fully compromise the product across supported versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0. Oracle rates this 9.8 (Critical) with full confidentiality, integrity, and availability impact and describes it as easily exploitable, meaning no authentication, credentials, or user interaction are needed. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the combination of unauthenticated network reach and complete compromise makes this a high-priority patch item.
RemediationAI
Apply the fixes from Oracle's July 2026 Critical Patch Update as the primary remediation; consult https://www.oracle.com/security-alerts/cpujul2026.html for the exact patch bundle mapped to each affected release (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, 15.1.1.0.0), as Oracle CPU patches are cumulative and version-specific - Patch available per vendor advisory, with no standalone fixed build number provided in this input. Until patched, restrict network reachability of Coherence's HTTP/cluster interfaces by placing them behind firewalls or internal-only segments and blocking untrusted access to Coherence management and cluster ports, accepting that overly aggressive port restrictions can disrupt legitimate cluster communication and must be validated in a test environment. Where Coherence exposes HTTP/REST management endpoints that are not required, disable them or bind them to loopback/internal interfaces to shrink the unauthenticated attack surface. Ensure Coherence is never directly internet-exposed and monitor for anomalous HTTP requests to Coherence endpoints as a detective control.

Technical ContextAI · show details
Oracle Coherence is an in-memory data grid and distributed caching/clustering platform bundled within Oracle Fusion Middleware, commonly used to scale Java (WebLogic) application state across a cluster. The flaw resides in the Core component and is reachable over HTTP, indicating exposure through Coherence's networked clustering/management or REST/HTTP-facing interfaces rather than a local console. Oracle did not assign a CWE (listed as N/A), so the precise root-cause class is unconfirmed; the 'takeover' outcome combined with Coherence's history of Java-based deserialization/injection issues is consistent with an unsafe-deserialization or remote-code-execution style weakness, but this specific mechanism is not stated in the provided data. The affected CPE is cpe:2.3:a:oracle_corporation:oracle_coherence, and the vendor tag references 'Information Disclosure' though the CVSS reflects far broader impact than disclosure alone.

DescriptionCVE.org
Vulnerability in the Oracle Coherence product of Oracle Fusion Middleware (component: Core). Supported versions that are affected are 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Coherence. Successful attacks of this vulnerability can result in takeover of Oracle Coherence. 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).
Executive ViewAI
Oracle Coherence, a foundational component of Oracle Fusion Middleware used throughout enterprise infrastructure, is vulnerable to unauthenticated remote takeover that grants complete system compromise through HTTP network access alone. Organizations running any of the four affected versions (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, 15.1.1.0.0) face immediate risk of data exfiltration, operational disruption, and loss of control without requiring any user credentials or interaction. With no vendor patch available, rapid containment and monitoring are the only interim defenses.
No vendor-released patch identified at time of analysis. Implement immediate network segmentation to restrict HTTP access to Coherence instances to essential systems only and deploy authentication wrappers or reverse proxies where possible. Activate continuous network monitoring and intrusion detection signatures to identify exploitation attempts. Establish a formal patch readiness program and expedited change management process for urgent Oracle Coherence updates when released.
