CVE-2014-4255
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnspecified vulnerability in the Oracle WebLogic Server component in Oracle Fusion Middleware 10.3.6.0, 12.1.1.0, and 12.1.2.0 allows remote attackers to affect confidentiality, integrity, and availability via vectors related to WLS - Security and Policy.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

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 WebLogic Server installation versionCheck the WebLogic installation by inspecting the registry file (registry.xml in the Oracle home directory) or the manifest file (weblogic.jar META-INF/MANIFEST.MF). On Windows, check HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\WebLogic in the registry. On Linux/Unix, check the installation log files or run 'java -jar wlserver_*.jar -mode=inspect'Affected if The installed version matches 10.3.6.0, 12.1.1.x, or 12.1.2.0.0
-
Confirm the WLS Security and Policy component is in useVerify that the WebLogic Server domain uses the default security framework. Check the domain configuration file (config.xml) for the presence of the <security> element and verify the Security and Policy realm is configured. This is typically present by default in standard WebLogic installations.Affected if The domain is configured with the default Security and Policy realm, which is the default configuration in affected versions
-
Check WebLogic Administration Console version displayLog into the WebLogic Administration Console and navigate to the 'About WebLogic Server' page or check the home page which displays the version number. Alternatively, check the startup logs or the DOMAIN_NAME/servers/AdminServer/logs/AdminServer.log for the version string at startup.Affected if The displayed version corresponds to any of the affected versions listed (10.3.6.0, 12.1.1.x, 12.1.2.0.0)
If the installed WebLogic Server version is 10.3.6.0, 12.1.1.x, or 12.1.2.0.0 and the Security and Policy subsystem is active (default configuration), the environment is affected by this CVE.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the Oracle Critical Patch Update (CPU) that addresses CVE-2014-4255. Prior to production deployment, test the patch in a non-production environment to ensure compatibility with existing WebLogic applications and configurations.
