Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify JD Edwards EnterpriseOne Tools versionLocate the Tools installation directory and check the version. The version is typically recorded in the 'jde.ini' or 'jdelog.properties' file in the Tools installation path, or can be retrieved via Oracle Enterprise Manager. Look for a 'Release' or 'ToolsVersion' parameter.Affected if The installed version number is lower than 9.2.9.0
-
Confirm Web Runtime (HTML Server) is enabledCheck the HTML Server configuration in the JD Edwards EnterpriseOne Administration Console or review the 'jas.ini' file in the Tools web runtime directory. Verify the 'Server' or 'HTML Server' instance is in a running or configured state.Affected if The Web Runtime SEC component is installed and accessible over HTTP/HTTPS
-
Verify network accessibility of Web RuntimeAttempt to access the Web Runtime endpoint (typically on port 8000 or 8080 for the HTML Server). Use a browser or curl to hit the login page or main endpoint: http://server:port/jde/ or the equivalent path for the EnterpriseOne web client.Affected if The Web Runtime is reachable over the network on HTTP/HTTPS ports
-
Check for recent crashes or hangsReview the JD Edwards HTML Server logs (jde.log, jde_CallObject.log) and Web container logs (Oracle WebLogic or Apache) for signs of application hangs, crashes, or unexpected termination events around the time of requests.Affected if Logs show repeated crashes, hangs, or unresponsiveness in the Web Runtime SEC component
The environment is affected if JD Edwards EnterpriseOne Tools version is below 9.2.9.0 and the Web Runtime SEC component is enabled and accessible over the network.
