Error description

  • The IIB v10 and ACE v11 administration web user interfaces send
    the X-Frame-Origin header with a value of "SAMEORIGIN" with
    every request to provide protection against click jacking
    attacks.
    
    This header prevents the web user interface from
    being embedded in another website. While this is generally the
    preferred default for most users, some users wish to embed the
    web user interface within their own administrative dashboards
    which requires that the X-Frame-Options header not be
    set.
    
    This APAR introduces new configuration options that allow
    the X-Frame-Options header value to be changed or to prevent
    the header from being sent at all.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users IBM Integration Bus v10 and IBM App Connect Enterprise

    PROBLEM DESCRIPTION:
    The IIB v10 and ACE v11 administration web user interfaces send
    the X-Frame-Origin header with a value of "SAMEORIGIN" with
    every request to provide protection against click jacking
    attacks.
    
    This header prevents the web user interface from being embedded
    in another website. While this is generally the preferred
    default for most users, some users wish to embed the web user
    interface within their own administrative dashboards which
    requires that the X-Frame-Options header not be set.
    

Problem conclusion

  • A new setting has been added to v10 and v11 called
    "antiClickJackingOption".
    
    At v10 this setting is on the webadmin server component and can
    take one of the following values:
    
    * "SAMEORIGIN" - sets the X-Frame-Origin header to "SAMEORIGIN"
    * "DENY" - sets the X-Frame-Origin header to "DENY"
    * "disabled" - disables sending the X-Frame-Origin header. This
    disables anti clickjacking protection.
    
    This value can be changed by running mqsichangeproperties BROKER
    -b webadmin -o server -n antiClickJackingOption -v <VALUE>
    
    At v11 this setting is the RestAdminListener section of the
    node.conf.yaml or server.conf.yaml and can take one of the
    following values:
    
    * "SAMEORIGIN" - sets the X-Frame-Origin header to "SAMEORIGIN"
    * "DENY" - sets the X-Frame-Origin header to "DENY"
    * "" (the empty string) - disables sending the X-Frame-Origin
    header. This disables anti clickjacking protection.
