CVE-2026-71080 in Agile PLM MCAD Connector
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Agile PLM MCAD Connector product of Oracle Supply Chain (component: CAX Client). The supported version that is affected is 3.6. Difficult to exploit vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Oracle Agile PLM MCAD Connector executes to compromise Oracle Agile PLM MCAD Connector. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Agile PLM MCAD Connector accessible data as well as unauthorized read access to a subset of Oracle Agile PLM MCAD Connector accessible data. CVSS 3.1 Base Score 3.7 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N).

The vulnerability identified in the Oracle Agile PLM MCAD Connector, specifically within version 3.6 and its CAX Client component, represents a significant risk to organizations relying on this software for product lifecycle management integration with CAD systems. This flaw is classified as an attack vector that requires physical proximity to the hardware executing the connector service, categorizing it under local or adjacent network attacks rather than remote exploitation over the public internet. The core technical issue stems from insufficient authentication mechanisms within the communication protocols used by the CAX Client when interacting with connected engineering data systems. Because the component does not strictly enforce identity verification for all incoming requests on the physical communication segment, an attacker who gains access to this local network or hardware interface can interact directly with the service without providing valid credentials. This lack of authentication is a critical design flaw that undermines the integrity and confidentiality controls expected in enterprise software environments handling sensitive intellectual property data.
The operational impact of exploiting this vulnerability allows for unauthorized modifications and disclosures within the Oracle Agile PLM MCAD Connector accessible data space. Specifically, an attacker can perform unauthorized updates, inserts, or deletes against engineering records, bills of materials, and design specifications stored or processed by the connector. This directly compromises the integrity of product development workflows, potentially leading to corrupted designs, incorrect manufacturing instructions, or loss of critical project metadata. Furthermore, the vulnerability permits unauthorized read access to a subset of accessible data, which may include proprietary CAD files, revision histories, and configuration settings. While the impact on availability is not explicitly detailed in the base score, the compromise of confidentiality and integrity poses severe risks to intellectual property protection and operational continuity for manufacturing and engineering departments that depend on accurate product data.
From a classification perspective, this vulnerability aligns with CWE-287 Improper Authentication, as the system fails to adequately verify the identity of users or services before granting access to protected resources. The requirement for human interaction suggests that while technical exploitation is possible, it may be facilitated by social engineering tactics where an attacker tricks a legitimate user into performing an action on their own device or network segment, thereby bridging the gap between physical proximity and successful compromise. This aspect relates to ATT&CK technique T1078 Valid Accounts if the human interaction leads to credential misuse, although the primary flaw is the lack of authentication for unauthenticated access. The low complexity and high availability requirements indicate that while the attack path is constrained by physical access needs, the ease of exploitation once on-site makes it a notable concern for facilities with lax physical security protocols.
Mitigation strategies must focus on both technical controls and administrative policies to reduce the risk surface associated with this vulnerability. Organizations should implement strict network segmentation to isolate systems running Oracle Agile PLM MCAD Connector from general-purpose networks, ensuring that only authorized engineering workstations can communicate with the connector hardware. Physical access controls are paramount; facilities housing these servers must enforce badge access, surveillance, and restricted entry policies to prevent unauthorized individuals from connecting devices to the physical communication segments. Additionally, applying vendor-provided patches or updates is essential if available, as Oracle may have released fixes that introduce proper authentication checks for CAX Client communications. Administrators should also audit network traffic logs to detect anomalous connection attempts originating from untrusted sources and disable any unnecessary services or ports associated with the MCAD Connector on public-facing interfaces. Regular security assessments focusing on physical access controls and internal network segmentation will further harden the environment against this type of adjacent-network attack vector.
