a specially crafted URL to execute a script in a user's web browser within the
security context of the hosting web site after the URL is clicked. An attacker
might use this vulnerability to steal the user's cookie-based authentication 
credentials.

Before this fix, a user could start System Tasks or User Tasks that were not 
exposed to this user via undocumented URLs.

The new functionality is:

"With URLs it is possible,

  to start Human Services that are exposed to the logged-on user

  to start Ajax Services.

Execution of other service types is rejected, unless

  the request arrives on the Process Center and

  the request was issued by Process Designer in a playback session and

  the user that issued this request is a member of the tw_authors group and

  the user is granted Read access to the process app.

If this behaviour conflicts with existing solutions, it is possible to disable
the new checks.

To do this, add

<server merge="mergeChildren">

<web-workflow-manager merge="mergeChildren">

<enforce-correct-service-type-for-execute-service-by-name>false</enforce-correct-service-type-for-execute-service-by-name>

</web-workflow-manager>
