APAR status

  • Closed as program error.

Error description

  • When a user provides input via a Coach, any special characters
    contained within that data are escaped (special characters are
    converted to their XML entity equivalents?for example, the <
    symbol is converted to &lt;). This is done as a security measure
     to guard against cross-site scripting attacks.
    This might pose a problem for the customer's application,
    depending on how that user input is used.
    
    PRODUCTS AFFECTED :
    IBM Business Process Manager (BPM) Advanced
    IBM BPM Standard
    IBM BPM Express
    

Local fix

  • The workaround would be for the customer to code their own
    function to convert the XML entities back to their equivalent
    special characters.
    

Problem summary

  • User input received via a coach might contain escaped special
    characters.
    

Problem conclusion

  • A fix is available for IBM BPM V8.0.1.2 that introduces a new
    api unescapeHtml(String str) which returns a string not
    containing any escaped special characters.  This API is part of
    the tw.system namespace. The input is the string to unescape or
    null.
    
    This fix also introduces another api escapeHtml(String str)
    which returns a string with escaped special characters (if any).
    This API is also part of the tw.system namespace. The input is
    the string to escape of null.
