Hidden pages' content can be viewed without permission using diffpages.action

XMLWordPrintable

      If the id of a page is known by a user, that user can view the content of the page without having permissions to the space it is in. They need only construct the right URL.
      EG:
      Two spaces A and B
      Page with id 1 is in Space A
      Page with id 2 is in Space B
      User cannot see Space A
      User can see Space B

      The following URL will allow the user to view a diff of the two pages, thus easily deriving the content of the page in the hidden space.

      http://confluence.example.com/pages/diffpages.action?pageId=2&originalId=1

            I attached patched class files for versions 2.8.2 and 2.7.3 of Confluence. Please refer to the installation instructions.

            The subdirectories for the class file are com/atlassian/confluence/pages/actions/. You need to remove the "-<version>" from the class file before copying it.
