CVE-2022-23620Network attack vector

Arbitrary file write via SSX reference traversal

Published Feb 9, 2022 · Updated Apr 23, 2025

Path traversal in XWiki Platform 6.2-rc-1 through 13.5 allows remote authenticated users to write files outside the HTML export directory. AbstractSxExportURLFactoryActionHandler.processSx builds a filesystem path from unescaped SSX or JSX document names, allowing ../ segments to escape the export directory. Exploitation requires script or subwiki-administrator rights and a user-triggered HTML or PDF export; resulting writes can overwrite files accessible to the server process.
