CVE-2014-4256
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 10.0.2.0, 10.3.6.0, 12.1.1.0, and 12.1.2.0 allows remote attackers to affect confidentiality and integrity via vectors related to WLS - Deployment.
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.
dbcve analysis · moderate confidenceUnspecified vulnerability in Oracle WebLogic Server's deployment functionality allows remote attackers to affect confidentiality and integrity. The flaw exists in versions 10.0.2.0, 10.3.6.0, 12.1.1.0, and 12.1.2.0, likely allowing unauthorized deployment configuration manipulation or deployment file access.

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 and versionCheck for WebLogic Server by looking for the installation directory (commonly under $ORACLE_HOME or /opt/oracle/wlserver) and run: java -jar -version 2>&1 | grep -i weblogic or check the registry file (registry.xml) in the wlserver_10.3 or wlserver_12.1 directory for the version tagAffected if The installed version matches 10.0.2.0, 10.3.6.0, 12.1.1.0, or 12.1.2.0
-
Verify deployment interface accessibilityCheck if WebLogic Server console (typically ports 7001/7002) or the deployment interface is exposed to untrusted networks by reviewing firewall rules: iptables -L -n or netstat -tlnp | grep -E '700[12]'Affected if The WebLogic Server administration port is reachable from untrusted networks (not limited to localhost or trusted internal subnets)
-
Confirm WebLogic deployment functionality is enabledCheck if the WebLogic Server deployment service is active by examining the config.xml file in the domain directory (typically <domain>/config/config.xml) for <deployment> elements, or check if the Admin Server process is runningAffected if WebLogic Server is running with deployment functionality enabled (standard default configuration)
-
Inspect deployment configuration for exposureReview the WebLogic domain configuration for any deployment-related directories or staging modes: ls -la <domain>/servers/*/stage/ and check config.xml for <staging-mode> settingAffected if Staging directories exist and are readable, or staging-mode is set to 'stage' or 'nostage' without proper access controls
A user is affected if WebLogic Server version 10.0.2.0, 10.3.6.0, 12.1.1.0, or 12.1.2.0 is installed, the server is running, and the deployment interface is network-accessible.

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 addressing CVE-2014-4256, or manually patch WebLogic Server to a supported version. Restrict WLS deployment interface access to trusted networks until patched.
