Remediation/Fixes

If you are not installing a fixed level of the CDC code, then the installation package is vulnerable to this security issue and you must use the workaround provided below to prevent being exposed to the vulnerability.

The fixed level of the CDC code can be obtained for the version 11.3.3 builds at the following location

http://www.ibm.com/support/fixcentral/swg/quickorder?parent=ibm~Information%2BManagement&product=ibm/Information+Management/IBM+InfoSphere+Data+Replication&release=11.3.3&platform=Windows&function=all&source=fc

The fix is available as of the following build numbers

IBM InfoSphere Data Replication Management Console for Windows 11.3.3.3 Build 5467, or greater
IBM InfoSphere Data Replication Access Server for Windows 11.3.3.3 Build 5467, or greater
IBM InfoSphere Data Replication CDC for all Windows agents 11.3.3.3 Build 43, or greater

Workarounds and Mitigations

Install the product or refresh pack by running the installation wizard or by running a silent installation:

To avoid an untrusted search path vulnerability where users could gain increased privileges, perform the following additional steps:

1. Clear all contents (files, sub-directories and etc.,) of your default download directory/location, if any.
2. Create a new secure directory in temporary location (such that elevated privileges are required to access this directory).
3. Copy/extract the setup.exe executable to the secure directory created in Step 2.
4. Launch the executable from the secure directory and wait until it completes.
