How do I fix CVE-2024-37898?

Update org.xwiki.platform:xwiki-platform-oldcore to 14.10.21 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-37898 is resolved across your whole dependency graph.

How do I detect CVE-2024-37898 in my Maven dependencies?

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

How do I mitigate CVE-2024-37898 if there is no patch (or I can't update yet)?

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.

Is CVE-2024-37898 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-37898 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

Impact

When a user has edit but not view right on a page in XWiki, that user can delete the page and replace it by a page with new content without having delete right. The previous version of the page is moved into the recycle bin and can be restored from there by an admin. As the user is recorded as deleter, the user would in theory also be able to view the deleted content, but this is not directly possible as rights of the previous version are transferred to the new page and thus the user still doesn't have view right on the page. From all we examined, it therefore doesn't seem to be possible to exploit this to gain any rights.

To reproduce, just replace view by edit in the URL of a page that you cannot view but edit and save. This should send the page to the recycle bin and replace it by an empty one if the XWiki installation is vulnerable. After the fix, an error is displayed when saving.

Patches

This has been patched in XWiki 14.10.21, 15.5.5 and 15.10.6 by cancelling save operations by users when a new document shall be saved despite the document's existing already.

Workarounds

We're not aware of any workarounds.
