# Oracle JD Edwards EnterpriseOne Tools: installation security flaw allows data changes

Oracle JD Edwards EnterpriseOne Tools versions 9.2.0.0 through 9.2.26.5 contain an Installation Security flaw. A local attacker who can log on to the host can modify or delete data, read a subset of data, and crash the tools, but only if a person other than the attacker takes an action.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed EnterpriseOne Tools release against the affected range 9.2.0.0-9.2.26.5 (version check method unknown)
- Confirm which hosts run JD Edwards EnterpriseOne Tools and who has logon access to them (unknown from sources)

## Fix

- Move JD Edwards EnterpriseOne Tools to a release outside 9.2.0.0-9.2.26.5 per Oracle's July 2026 Critical Patch Update guidance (exact fixed version unknown)
- Restrict local logon access to the infrastructure that runs EnterpriseOne Tools until patched

## From the sources

Vulnerability in the JD Edwards EnterpriseOne Tools product of Oracle JD Edwards (component: Installation Security).  Supported versions that are affected are 9.2.0.0-9.2.26.5. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where JD Edwards EnterpriseOne Tools executes to compromise JD Edwards EnterpriseOne Tools.  Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in  unauthorized creation, deletion or modification access to critical data or all JD Edwards EnterpriseOne Tools accessible data as well as  unauthorized read access to a subset of JD Edwards EnterpriseOne Tools accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of JD Edwards EnterpriseOne Tools. CVSS 3.1 Base Score 6.5 (Confidentiality, Integrity and Availability impacts).  CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:H/A:H).
