Unprivileged XWiki Platform users can make arbitrary select queries using DatabaseListProperty and suggest.vm

Impact

Any user with edit right can execute arbitrary database select and access data stored in the database.

To reproduce:

• In admin, rights, remove scripting rights for {{XWikiAllGroup}}.
• Create a new user without any special privileges.
• Create a page "Private.WebHome" with {{TOKEN_42}} as content. Go to "page administration" and explicitly set all rights for "Admin" to remove them for all other users.
• Logout and login as the unprivileged user. Ensure that the previously created page cannot be viewed.
• Create a new page "ExploitClass.WebHome" and then open it in the class editor (first, make the user an advanced user).
• Add a field named {{ContentList}} of type {{Database List}}
• Enter in field "Hibernate Query" the following content: {noformat}select doc.content, doc.fullName from XWikiDocument as doc where doc.fullName = 'Private.WebHome'{noformat}
• Save the class.
• Open [http://localhost:8080/xwiki/bin/view/ExploitClass/?xpage=suggest&classname=ExploitClass.WebHome&fieldname=ContentList&firCol=doc.fullName&secCol=-]
