Vulnerability Details CVEID: CVE-2017-1199 DESCRIPTION: IBM InfoSphere Master Data Management Server is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. CVSS Base Score: 5.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/123674 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) Affected Products and Versions This vulnerability is known to affect the following offerings: Affected IBM InfoSphere Master Data Affected Versions Management Server IBM InfoSphere Master Data Management Server 10.1 IBM InfoSphere Master Data Management Server 11.0 IBM InfoSphere Master Data Management Server 11.3 IBM InfoSphere Master Data Management Server 11.4 IBM InfoSphere Master Data Management Server 11.5 Remediation/Fixes The recommended solution is to apply the fix as soon as practical. Please see below for information on how to apply the fix: If you have customized the UI and the source code is already available skip step #1 and #2. 1. Locate the com.ibm.mdm.sample.ds.webapp.ear.zip file from MDM sample. 2. Import the projects into RAD and follow Downloading, configuring and deploying the sample 3. Open SessionFilter.java from CommonUIModel - - In doFilter method add the below code provided code at line number 75 httpResponse.setHeader("Content-Security-Policy", "default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; connect-src 'self'; img-src 'self'; style-src 'self' 'unsafe-inline'"); //#Used by Firefox until version 23, and Internet Explorer version 10 (which partially implements Content Security Policy). httpResponse.setHeader("X-Content-Security-Policy", "default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; connect-src 'self'; img-src 'self'; style-src 'self' 'unsafe-inline'"); //Used by Chrome until version 25 httpResponse.setHeader("X-WebKit-CSP", "default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; connect-src 'self'; img-src 'self'; style-src 'self' 'unsafe-inline'"); //https://www.owasp.org/index.php/List_of_useful_HTTP_headers httpResponse.setHeader("X-Content-Type-Options","nosniff"); httpResponse.setHeader("X-XSS-Protection","1"); //one year = 31536000 httpResponse.setHeader("Strict-Transport-Security","max-age=31536000"); - - After the code changes are done build all projects 4. Export CustomerDataStewardship as EAR Then From RAD, File -> Export -> Ear File (Under Java EE) in EAR Export wizard - - select EAR Project name as 'CustomerDataStewardship' - - Then provide the destination , that earfile name 5. Deploy the this new exported EAR on server Note: Before installing EAR on server make sure ClientAuthentication.properties and mdmUIConfiguration.properties of propertiesUI.jar have valid connection properties.
