Pg. 16-Pg 19

Limit communication between DataStage Windows Client and Server to be via
trusted networks (VPN, Firewall, Private Networks) only

Monitor access from DataStage Windows Client to DataStage Server

DataStage Client and Server requires a single port to be
opened (default 31538) for communication. Limit opening
any other ports between client and server as documented:

Security Bulletin: IBM InfoSphere Information Server is potentially
vulnerable to XML External Entity Injection (XXE)

Document information

More support for: InfoSphere Information Server

Software version: 9.1, 11.3, 11.5

Operating system(s): AIX, HP-UX, Linux, Solaris, Windows

Reference #: 2005803

Modified date: 31 July 2017

Security Bulletin

Summary

An XML External Entity Injection (XXE) vulnerability in IBM InfoSphere
Information Server potentially can be used by an attacker to retrieve
sensitive documents.

Importing from the DataStage Designer Client is a feature that enables
users to migrate DataStage assets from one system to another or from one
project to another in the same system.

Examples:
Migrating Jobs from a Development system to a Production system
Performing DataStage version upgrades (i.e. v11.3 to v11.5)
Sharing assets between DataStage users/teams

IBM DataStage supports three different formats to export  DataStage objects:
DSX (DataStage eXport format)
XML
ISX

There is a potential vulnerability when existing DataStage assets are
imported via XML.

Likewise, there is a potential vulnerability in XML Plugin's metadata
import operations.

Vulnerability Details

CVEID: CVE-2017-1383
DESCRIPTION: IBM InfoSphere Information Server is vulnerable to a XML
External Entity Injection (XXE) attack when processing XML data. A remote
attacker could exploit this vulnerability to expose sensitive information
or consume memory resources.
CVSS Base Score: 7.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/127155 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L)

Affected Products and Versions

The following products, running on all supported platforms, are affected:
IBM InfoSphere DataStage: versions 9.1, 11.3, and 11.5
IBM InfoSphere Information Server on Cloud: version 11.5

Remediation/Fixes

None

Workarounds and Mitigations

Mitigation Steps:

DataStage import operations

Limit import of DataStage assets to DSX (Default) or ISX formats, only.
If XML format is used for import, manually check the XML file before
importing the file to determine if there is a DTD / DOCTYPE section. DTD
sections are optional in DataStage XML files, and if present, can be safely
removed before importing.
Additionally, use the istools command line utility that supports both
export and import in ISX format.

Examples on the use of istools command line utility can be found in the
links below:
https://www.ibm.com/support/knowledgecenter/en/SSZJPZ_11.5.0/com.ibm.swg.im.iis.productization.iisinfsv.migrate.doc/topics/a_exporting_projects.html

https://www.ibm.com/support/knowledgecenter/en/SSZJPZ_11.3.0/com.ibm.swg.im.iis.iisinfsv.assetint.doc/topics/istoolimp.html
www.redbooks.ibm.com/redbooks/pdfs/sg247830.pdf  Pg. 50 - Pg. 54

XML Metadata importer operations for XML Input and XML Output plugin stages

XML Metadata Importer is used to create table definitions from XML sources
i.e. XML Schemas and XML documents. IBM recommends manually checking the
XML file content before importing the file. If there is a DTD / DOCTYPE
section, verify its contents for any vulnerabilities.
DTD sections are required in some XML files else the metadata imported
may be incomplete which could be due to missing DTD Entities data.
XML Schema Definition (XSD) language is the current standard schema
language for all XML documents and data. So, IBM recommends using XSD as
an alternative to DTD.
