CVE-2013-5391
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 · uneditedIBM Worklight Consumer and Enterprise Editions 5.0.x before 5.0.6 Fix Pack 2 and 6.0.x before 6.0.0 Fix Pack 2, and Mobile Foundation Consumer and Enterprise Editions 5.0.x before 5.0.6 Fix Pack 2 and 6.0.0 Fix Pack 2 make it easier for attackers to defeat cryptographic protection mechanisms by leveraging improper initialization of the pseudo random number generator (PRNG) in Android and use of the Java Cryptography Architecture (JCA) by a Worklight program. IBM X-Force ID: 87128.
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 · high confidenceIBM Worklight and Mobile Foundation editions have a vulnerability where the Android platform's Pseudo Random Number Generator (PRNG) is improperly initialized, and the application makes improper use of the Java Cryptography Architecture (JCA). This results in weakened cryptographic protections, potentially allowing attackers to predict or recover cryptographic keys used by the application.

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 if Android platform is in useDetermine whether your IBM Worklight or Mobile Foundation environment is being used to build, deploy, or manage Android mobile applications. Check your project configurations or application build targets for Android platform references.Affected if The environment builds or deploys Android applications using IBM Worklight or Mobile Foundation
-
Check installed IBM Worklight versionLocate the IBM Worklight installation directory and check the product version. Look for version information in the installation files, about dialog, or version metadata file. Common locations include the installation root or product-specific configuration directories.Affected if The installed version is 5.0.0.0, 5.0.5.0, 5.0.6.0, or 6.0.0.0
-
Check installed IBM Mobile Foundation versionLocate the IBM Mobile Foundation installation and verify the product version. Check the installation root directory, product metadata, or version information file for the exact version number.Affected if The installed version is 5.0.0.0, 5.0.5.0, 5.0.6.0, or 6.0.0.0
-
Inspect cryptographic configuration for AndroidIf accessible, examine the cryptographic configuration files or code within Android application modules built using the IBM product. Look for PRNG initialization settings and JCA configuration in the Android-specific application build or runtime configuration.Affected if The cryptographic implementation uses default Android PRNG without proper initialization or uses JCA incorrectly for Android platform operations
Your environment is affected if you use IBM Worklight or Mobile Foundation versions 5.0.0.0, 5.0.5.0, 5.0.6.0, or 6.0.0.0 to build or deploy Android applications with the vulnerable cryptographic implementation.

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 IBM Fix Pack 2 for version 5.0.6 or Fix Pack 2 for version 6.0.0 to address the improper PRNG initialization and JCA usage. This is a patch update that replaces the vulnerable cryptographic implementation.
