{"id":"GHSA-4f8m-7h83-9f6m","summary":"XWiki Platform vulnerable to CSRF privilege escalation/RCE via the create action","details":"### Impact\nThe 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.\n\n### Patches\nThis has been patched in XWiki 14.10.9 and 15.4RC1 by requiring a CSRF token for the actual page creation.\n\n### Workarounds\nThere are no known workarounds.\n\n### References\n* https://jira.xwiki.org/browse/XWIKI-20849\n* https://github.com/xwiki/xwiki-platform/commit/4b20528808d0c311290b0d9ab2cfc44063380ef7","aliases":["CVE-2023-40572"],"modified":"2026-09-10T03:49:57.367164345Z","published":"2023-08-23T20:37:04Z","database_specific":{"cwe_ids":["CWE-352"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2023-08-23T20:37:04Z","nvd_published_at":"2023-08-24T02:15:09Z"},"references":[{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-4f8m-7h83-9f6m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-40572"},{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform/commit/123e5d7e4ca06bf75b95aaef665aafc4fa9cae64"},{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform/commit/4b20528808d0c311290b0d9ab2cfc44063380ef7"},{"type":"PACKAGE","url":"https://github.com/xwiki/xwiki-platform"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-20849"}],"affected":[{"package":{"name":"org.xwiki.platform:xwiki-platform-oldcore","ecosystem":"Maven","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-oldcore"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.2-milestone-3"},{"fixed":"14.10.9"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/08/GHSA-4f8m-7h83-9f6m/GHSA-4f8m-7h83-9f6m.json"}},{"package":{"name":"org.xwiki.platform:xwiki-platform-oldcore","ecosystem":"Maven","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-oldcore"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"15.0-rc-1"},{"fixed":"15.4-rc-1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/08/GHSA-4f8m-7h83-9f6m/GHSA-4f8m-7h83-9f6m.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H"}]}
