CVE-2026-71078 Oracle Corporation CVE debrief

Who should care

System administrators and security professionals responsible for Oracle Agile PLM MCAD Connector installations should be aware of this vulnerability and take necessary actions to mitigate it.

Technical summary

The vulnerability exists in the CAX Client component of Oracle Agile PLM MCAD Connector version 3.6. It has a CVSS 3.1 Base Score of 4.2, indicating Medium severity. The vulnerability is difficult to exploit and requires human interaction from a person other than the attacker. Successful exploitation could lead to 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 and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Agile PLM MCAD Connector. System administrators should focus on applying vendor patches and ensuring proper access controls are in place to mitigate this vulnerability. The CVSS Vector is (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L). This vulnerability allows a low-privileged attacker with logon to the infrastructure where Oracle Agile PLM MCAD Connector executes to compromise Oracle Agile PLM MCAD Connector. The affected component and version increase the attack surface, emphasizing the need for prompt patching and access control reviews. The vulnerability's Medium severity highlights the importance of applying security patches and maintaining strict access controls to protect against potential exploitation. The vulnerability's impact on confidentiality, integrity, and availability underscores the need for swift mitigation efforts. The CVSS score and vector provide a quantitative measure of the vulnerability's severity, aiding in prioritization of mitigation efforts. The vulnerability's exploitation requires human interaction, which may limit its immediate impact but does not diminish the need for thorough mitigation strategies. The potential for unauthorized data access and partial DOS necessitates a comprehensive response, including patching, monitoring, and compensating controls. The Oracle Agile PLM MCAD Connector's functionality and the vulnerability's characteristics suggest that defenders should prioritize patching and access control measures to minimize potential damage. The vulnerability's details and impact emphasize the importance of maintaining up-to-
