Enabling URL redirect filtering

When you enable URL redirect filtering, HCL Commerce rejects any requests that try to redirect to an unauthorized site. This feature is used to prevent phishing attacks where a link in an HCL Commerce site sends the shopper to another site.

Examples of URL redirection include:
  • URL parameter in a URL command
  • reLogonURL in Logon URL command
  • URLs defined as click actions in the Marketing Tool. For example, select * from collateral where URL like 'http%'

Procedure

  1. Open the HCL Commerce configuration file.
    • For a local store (migrated from IBM Websphere Commerce Version 7 or IBM Websphere Commerce Version 8), this is located within the Transaction server Docker container (ts-app).
    • For a remote store, this is located within the Store server Docker container (crs-app).
  2. Locate the web module where you want to enable this feature.
    For example, if you want to enable this feature for the Stores web module, modify the following section:
    <Module contextPath="/webapp/wcs/stores"
    	fileServletEnabled="false" name="Stores"
    	urlMappingPath="/servlet" webAlias="/wcsstore">
    	<InitParameters adapters="XML/HTTP, BrowserAdapter" 
    	contextSetName="Store" handleDoubleClick="true"/>
    </Module>
    
    Note: If you want to enable this feature for store preview, you must modify the module context path as followed: Module contextPath="/webapp/wcs/preview".
  3. Add a URLRedirectFilter element in the Module element as shown in the following example:
    <Module contextPath="/webapp/wcs/stores" 
    	fileServletEnabled="false" name="Stores"
    	urlMappingPath="/servlet" webAlias="/wcsstore">
    	<InitParameters adapters="XML/HTTP, BrowserAdapter" 
    	contextSetName="Store" handleDoubleClick="true"/>
    	<URLRedirectFilter enable="true">
    	<AllowedHost name="www.mycompany1.com"/>
    	<AllowedHost name="www.mycompany2.com"/>
    	<AllowedDomain name="mycompany3.com"/>
    	</URLRedirectFilter>
    </Module>
    

    The usage of these elements is described in the following list:

    URLRedirectFilter enable="true"
    Specifies whether cross-site scripting protection is enabled. Possible values are true or false.
    AllowedHost hostname="www.mycompany1.com"
    Specifies a hostname that HCL Commerce allows redirection to. By default, if this feature is enabled, the Web server hostname that is configured for the HCL Commerce instance is added to the allowed host list.
    AllowedDomain name="mycompany3.com"
    Specifies an entire domain that HCL Commerce allows redirection to. Use this element if you want to allow redirection to all hosts in a domain.

Example

In the preceding example URL redirection from the Stores web module is enabled. HCL Commerce allows redirection from the Stores web module to any of the following hosts:
  • www.mycompany1.com
  • www.mycompany2.com
  • www.mycompany3.com
  • myhost.mycompany3.com
  • myhost2.mycompany3.com

The following hosts would be blocked by HCL Commerce:

  • www.mycompany4.com
  • myhost.mycompany1.com

What to do next

Package your changes to the HCL Commerce configuration file for deployment.
