{"id":"GHSA-cmvg-w72j-7phx","summary":"org.xwiki.platform:xwiki-platform-skin-skinx vulnerable to basic Cross-site Scripting by exploiting JSX or SSX plugins","details":"### Impact\n\nThere was no check in the author of a JavaScript xobject or StyleSheet xobject added in a XWiki document, so until now it was possible for a user having only Edit Right to create such object and to craft a script allowing to perform some operations when executing by a user with appropriate rights. \n\n### Patches\n\nThis has been patched in XWiki 14.9-rc-1 by only executing the script if the author of it has Script right. \n\n### Workarounds\n\nThe only known workaround consists in applying [the following patch](https://github.com/xwiki/xwiki-platform/commit/fe65bc35d5672dd2505b7ac4ec42aec57d500fbb) and rebuilding and redeploying `xwiki-platform-skin-skinx`.\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [Jira](http://jira.xwiki.org)\n* Email us at [Security ML](mailto:security@xwiki.org)\n","aliases":["CVE-2023-29206"],"modified":"2023-11-08T04:12:17.637436Z","published":"2023-04-12T20:38:47Z","database_specific":{"github_reviewed_at":"2023-04-12T20:38:47Z","nvd_published_at":"2023-04-15T16:15:00Z","cwe_ids":["CWE-79"],"severity":"CRITICAL","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-cmvg-w72j-7phx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-29206"},{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform/commit/fe65bc35d5672dd2505b7ac4ec42aec57d500fbb"},{"type":"PACKAGE","url":"https://github.com/xwiki/xwiki-platform"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-19514"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-19583"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-9119"}],"affected":[{"package":{"name":"org.xwiki.platform:xwiki-platform-skin-skinx","ecosystem":"Maven","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-skin-skinx"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0-milestone-1"},{"fixed":"14.9-rc-1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/04/GHSA-cmvg-w72j-7phx/GHSA-cmvg-w72j-7phx.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H"}]}
