CVE-2023-40572
CVSS v2.0
10
Critical
| Vector | AV:N/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
XWiki Platform versions prior to 14.10.9
XWiki Platform versions prior to 15.4RC1
Description
The create action in XWiki Platform is vulnerable to a CSRF attack, allowing script and thus remote code execution when targeting a user with script/programming right. This compromises the confidentiality, integrity, and availability of the whole XWiki installation. When a user with script right views a malicious image and a log message
ERROR foo - Script executed! appears in the log, the XWiki installation is vulnerable. The issue can be exploited by adding the XWiki syntax [[image:path:/xwiki/bin/create/Foo/WebHome?template=&parent=Main.WebHome&title=$services.logging.getLogger("foo").error("Script executed!")]] to any place that supports XWiki syntax.Recommendations
For XWiki Platform versions prior to 14.10.9, update to version 14.10.9 or later to patch the vulnerability by requiring a CSRF token for the actual page creation.
For XWiki Platform versions prior to 15.4RC1, update to version 15.4RC1 or later to patch the vulnerability by requiring a CSRF token for the actual page creation.
As a temporary workaround, consider restricting access to the create action to minimize the risk of exploitation.
