Vulnerability Details CVEID: CVE-2016-4560 DESCRIPTION: Flexera InstallAnywhere could allow a local attacker to gain elevated privileges on the system, caused by an untrusted search path. An attacker could exploit this vulnerability using a Trojan horse DLL in the current working directory of a setup-launcher executable file to gain elevated privileges on the system. CVSS Base Score: 7.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113016 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) Affected Products and Versions Affected CDC components include: Management Console Access Server (Windows-based version only) Replication engines (agents) for the following databases (Windows-based versions only) . DB2 for Linux, Unix and Windows . Datastage . Event Server . Hadoop . Informix . FlexRep . Microsoft SQL Server . Netezza . Oracle . PureScale Data System for Analytics . Sybase . Teradata The following product levels are affected: IBM InfoSphere Data Replication 11.3.3, 11.3.0, 10.2.1, 10.2.0, 10.1.3, 10.1.2, 10.1.1, 10.1.0 IBM InfoSphere Data Replication for Apache Hadoop 11.3.3 IBM InfoSphere Data Replication for Database Migration 11.3.3, 10.2.1, 10.1.3 IBM InfoSphere Data Replication for Netezza 11.3.0, 10.2.1, 10.2.0, 10.1.3, 10.1.2 IBM InfoSphere Data Replication for Non-Production Environments 10.2.1, 10.1.3 IBM InfoSphere Change Data Delivery 11.3.3, 11.3.0, 10.2.1, 10.2.0 IBM InfoSphere Change Data Delivery for Information Server 11.3.3, 11.3.0, 10.2.1, 10.2.0 IBM InfoSphere Change Data Delivery for Netezza 11.3.0, 10.2.1, 10.2.0 IBM InfoSphere Change Data Delivery for PureData System for Analytics 11.3.3, 11.3.0 IBM InfoSphere Change Data Delivery for Information Server for PureData System for Analytics 11.3.3 IBM InfoSphere Change Data Delivery for Information Server for Netezza 11.3.0, 10.2.1, 10.2.0 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.
