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 · unedited
IBM Runtime Environment, Java Technology Edition IBMJCEPlus and JSSE 8.0.7.0 through 8.0.7.11 components could expose sensitive information using a combination of flaws and configurations. IBM X-Force ID: 253188.

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 confidence

IBM Runtime Environment Java components IBMJCEPlus (cryptographic provider) and JSSE (SSL/TLS) versions 8.0.7.0 through 8.0.7.11 contain a combination of implementation flaws and insecure configuration options that can lead to exposure of sensitive information, likely cryptographic keys or plaintext data.

MitigationUpgrade IBM Runtime Environment Java to version 8.0.7.12 or later; review and harden IBMJCEPlus and JSSE configurations per IBM security guidance.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed IBM Java version
    Run 'java -version' or check the version file in the IBM Java installation directory (e.g., $JAVA_HOME/release or $JAVA_HOME/jre/release). Look for the version string (e.g., 8.0.7.x).
    Affected if The version is 8.0.7.0 through 8.0.7.11 (or 8.0.7.14 and below for IBM Java, since the fix is in 8.0.7.15+)
  2. Determine if IBMJCEPlus cryptographic provider is enabled
    Inspect the Java security properties file (java.security) in the JRE/lib/security directory. Look for a line configuring 'ibmJCEPlus' as a security provider, typically numbered like 'security.provider.N=com.ibm.crypto.ibmJCEPlus.IBMJCEPlusProvider'.
    Affected if IBMJCEPlus provider is listed and enabled in the security provider configuration
  3. Check for IBM JSSE (SSL/TLS) usage
    Review application server or Java application configuration files for SSL/TLS settings that reference IBM JSSE classes (com.ibm.jsse2.* or com.ibm.net.ssl.*). In WebSphere, check the SSL configuration panel or the security.xml file.
    Affected if IBM JSSE is configured or used for SSL/TLS connections in the application or application server
  4. Identify IBM WebSphere Application Server version
    If using WebSphere, check the version via the installation directory (e.g., aboutWebSphere.html) or the Installation Verification Tool (IVT). For traditional WAS, check the 'product.installroot' or version info file.
    Affected if WebSphere version is 8.5.0.0 through 8.5.5.22, any version 9.0.x prior to fixes, or bundled with vulnerable IBM Java versions in the 8.0.7.0-8.0.7.11 range
  5. Check for IBM InfoSphere Information Server version
    Verify if IBM InfoSphere Information Server version 11.7 is installed and check its bundled Java components. Review installation directories for IBM Java runtimes.
    Affected if InfoSphere Information Server 11.7 is deployed with bundled IBM Java in the vulnerable version range

You are affected if your environment uses IBM Java 8.0.7.0-8.0.7.11 (or WebSphere/InfoSphere with bundled vulnerable IBM Java) AND has IBMJCEPlus cryptographic provider or IBM JSSE SSL/TLS enabled for handling sensitive data.

Upgrade available Upgrade to 8.0.7.15 / 8.5.5.23 or later
Fixed in 8.0.7.158.5.5.23
Interim mitigation

Upgrade IBM Runtime Environment Java to version 8.0.7.12 or later; review and harden IBMJCEPlus and JSSE configurations per IBM security guidance.

Recommended fix High confidence

IBM Java 8.0.7.15+ or WebSphere Application Server 8.5.5.23+/9.0.0.5+

  1. Identify the affected IBM product in your environment (Java 8.0.7.x, WebSphere Application Server 8.5.x/9.0.x, or Infosphere Information Server 11.7)
  2. For IBM Java: upgrade to Java 8.0.7.15 or later (8.0.7.15 contains the fix for the IBMJCEPlus and JSSE vulnerabilities)
  3. For WebSphere Application Server: upgrade to version 8.5.5.23 or later, or migrate to WebSphere 9.0.0.5 or later which contains the fix
  4. After upgrading, verify that the IBMJCEPlus and JSSE providers are properly configured in the java.security file
  5. Restart all Java/WebSphere services to load the updated runtime
  6. Validate that applications function correctly with the updated cryptographic providers
Caveat Upgrading Java runtime may require regression testing of cryptographic operations; ensure custom cipher suites and key configurations are compatible with the updated JSSE provider
