{"cve":"CVE-2023-37913","nvd":{"published":"2023-10-25T18:17:28.687","modified":"2026-06-17T06:08:53.447","status":"Modified","description":"XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Starting in version 3.5-milestone-1 and prior to versions 14.10.8 and 15.3-rc-1, triggering the office converter with a specially crafted file name allows writing the attachment's content to an attacker-controlled location on the server as long as the Java process has write access to that location. In particular in the combination with attachment moving, a feature introduced in XWiki 14.0, this is easy to reproduce but it also possible to reproduce in versions as old as XWiki 3.5 by uploading the attachment through the REST API which doesn't remove `/` or `\\` from the filename. As the mime type of the attachment doesn't matter for the exploitation, this could e.g., be used to replace the `jar`-file of an extension which would allow executing arbitrary Java code and thus impact the confidentiality, integrity and availability of the XWiki installation. This vulnerability has been patched in XWiki 14.10.8 and 15.3RC1. There are no known workarounds apart from disabling the office converter.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-22","CWE-23"],"references":["https://github.com/xwiki/xwiki-platform/commit/45d182a4141ff22f3ff289cf71e4669bdc714544","https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vcvr-v426-3m3m","https://jira.xwiki.org/browse/XWIKI-20715","https://github.com/xwiki/xwiki-platform/commit/45d182a4141ff22f3ff289cf71e4669bdc714544","https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vcvr-v426-3m3m"],"products":["xwiki:xwiki"],"source":"nvd","synced_at":"2026-10-19T21:40:11.519948003+00:00"},"epss":{"cve":"CVE-2023-37913","score":0.01357,"percentile":0.7166,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-vcvr-v426-3m3m","url":"https://osv.dev/vulnerability/GHSA-vcvr-v426-3m3m","summary":"org.xwiki.platform:xwiki-platform-office-importer vulnerable to arbitrary server side file writing from account through office converter","modified":"2026-09-10T03:50:08.698067309Z","packages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-office-importer","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-office-importer","ranges":[">=3.5-milestone-1 <14.10.8"],"fixed":["14.10.8"]},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-office-importer","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-office-importer","ranges":[">=15.0-rc-1 <15.3-rc-1"],"fixed":["15.3-rc-1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
