  "summary" : "XWiki allows remote code execution from account through macro descriptions and XWiki.XWikiSyntaxMacrosList",
  "details" : "### Impact\nAny user with an account can perform arbitrary remote code execution by adding instances of `XWiki.WikiMacroClass` to any page. This compromises the confidentiality, integrity and availability of the whole XWiki installation.\n\nTo reproduce on a instance, as a connected user without script nor programming rights, go to your user profile and add an object of type `XWiki.WikiMacroClass`. Set \"Macro Id\", \"Macro Name\" and \"Macro Code\" to any value, \"Macro Visibility\" to `Current User` and \"Macro Description\" to `{{async}}{{groovy}}println(\"Hello from User macro!\"){{/groovy}}{{/async}}`.\nSave the page, then go to `<host>/xwiki/bin/view/XWiki/XWikiSyntaxMacrosList`.\nIf the description of your new macro reads \"Hello from User macro!\", then your instance is vulnerable.\n\n### Patches\nThis vulnerability has been fixed in XWiki 15.10.11, 16.4.1 and 16.5.0.\n\n### Workarounds\nIt is possible to manually apply [this patch](https://github.com/xwiki/xwiki-platform/commit/40e1afe001d61eafdf13f3621b4b597a0e58a3e3#diff-92fee29683e671b8bc668e3cf4295713d6259f715e3954876049f9de77c0a9ef) to the page `XWiki.XWikiSyntaxMacrosList`.\n\n### References\n\n* https://jira.xwiki.org/browse/XWIKI-22030\n* https://github.com/xwiki/xwiki-platform/commit/40e1afe001d61eafdf13f3621b4b597a0e58a3e3",
