Oracle JD Edwards EnterpriseOne Tools: Unauthorized data access via JDENET
Summary
Oracle JD Edwards EnterpriseOne Tools versions 9.2.0.0 to 9.2.26.5 contain a flaw in the Interoperability SEC component that is reachable via the JDENET network protocol. An authenticated attacker with low privileges and network access to JDENET can read, create, modify or delete data accessible to the JD Edwards EnterpriseOne Tools. No user interaction is required, and availability is not affected. The NVD record is still awaiting analysis, and the CVSS score and CWE differ between sources.
Affected
- Oracle JD Edwards EnterpriseOne Tools 9.2.0.0 to 9.2.26.5 (supported versions)
- Component: Interoperability SEC, protocol JDENET
- CVSS 3.1: 8.1 (NVD/CNA, CWE-200); VulDB lists 6.3 (CWE-269)
Fixed in
Unknown. The fix is expected in the Oracle Critical Patch Update of October 2026, but the patched release number was not verified. Check the advisory's patch availability table or My Oracle Support.
Workaround
Unknown. No vendor workaround was found. Restricting network access to JDENET with firewalls or VPN rules to trusted hosts only reduces exposure.
Exploitation
- No evidence of exploitation in the wild found; no CISA KEV entry found at time of research (recheck recommended).
- No public proof-of-concept found.
- CISA SSVC: exploitation none, automatable no, technical impact total.
Our recommendation
- If JD Edwards EnterpriseOne Tools is in use, treat this as high priority in the October 2026 patch cycle.
- Obtain the fixed release from the Oracle advisory or My Oracle Support and apply it.
- Make sure JDENET is not reachable from the internet and limit access to trusted hosts.
- Review which accounts can reach JDENET and remove unneeded access.
- Monitor JDENET traffic and JDE access logs for unusual data changes.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
