XWiki Platform vulnerable to CSRF privilege escalation/RCE via the create action
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.xwiki.platform:xwiki-platform-oldcore | >= 3.2-milestone-3, < 14.10.9 | 14.10.9 |
| Maven | org.xwiki.platform:xwiki-platform-oldcore | >= 15.0-rc-1, < 15.4-rc-1 | 15.4-rc-1 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
The create action is vulnerable to a CSRF attack, allowing script and thus remote code execution when targeting a user with script/programming right, thus compromising the confidentiality, integrity and availability of the whole XWiki installation. To reproduce, the XWiki syntax `[[image:path:/xwiki/bin/create/Foo/WebHome?template=&parent=Main.WebHome&title=$services.logging.getLogger(%22foo%22).error(%22Script%20executed!%22)]]` can be added to any place that supports XWiki syntax like a comment. When a user with script right views this image and a log message `ERROR foo - Script executed!` appears in the log, the XWiki installation is vulnerable.
### Patches
This has been patched in XWiki 14.10.9 and 15.4RC1 by requiring a CSRF token for the actual page creation.
### Workarounds
There are no known workarounds.
