Description

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=-]

Patches

The problem has been patched on XWiki 13.10.11, 14.4.7, and 14.10.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-web, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.xwiki.platform:xwiki-platform-web to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-26473 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
