Detailed vulnerability description
The vulnerability allows a remote user to execute arbitrary script code with elevated privileges.
The vulnerability exists due to incorrect privilege assignment in the link refactoring feature when renaming or moving the target of a link on a page. A remote user can create a page containing a link so that a later refactoring operation causes scripts contained in xobjects to be executed with elevated privileges to execute arbitrary script code with elevated privileges.
User interaction is required, as a user with more rights must perform the move or rename operation on the targeted page.
