Summary
IBM Worklight and IBM Mobile Foundation application authenticity verification
can be bypassed under certain conditions.
Vulnerability Details
CVEID: CVE-2014-0888
DESCRIPTION: The application authenticity feature in IBM Worklight and IBM
Kobile Foundation enables the Worklight server to validate that the Worklight
client application has not been tampered with. Under certain conditions, a
third party may be able to bypass the application authenticity validation and
modify the client application.

Remediation/Fixes
The application authenticity validation feature has been strengthened in IBM
Worklight Foundation Version 6.2.0.0. You can upgrade the Worklight server and
Worklight client applications to version 6.2.0.0.
Workarounds and Mitigations
The application authenticity validation feature might be bypassed more easily
if the Android versions of the Worklight client application are shipped with
debug mode enabled. The debug mode is specified in the AndroidManifest.xml
file with the android:debuggable attribute of the application element. Ensure
that this attribute is not set to true.
Utilizing only official mobile application stores for application distribution
and installation reduces the chances of client application tampering.
