XWiki Platform is a generic wiki platform. Starting in version 9.7-rc-1 and prior to versions 15.10.11, 16.4.1, and 16.5.0, any 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. This vulnerability has been fixed in XWiki 15.10.11, 16.4.1 and 16.5.0. It is possible to manually apply the patch to the page `XWiki.XWikiSyntaxMacrosList` as a workaround.

### Impact Any 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. To 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}}`. Save the page, then go to `<host>/xwiki/bin/view/XWiki/XWikiSyntaxMacrosList`. If the description of your new macro reads "Hello from User macro!", then your instance is vulnerable. ### Patches This vulnerability has been fixed in XWiki 15.10.11, 16.4.1 and 16.5.0. ### Workarounds It is possible to manually apply [this patch](https://github.com/xwiki/xwiki-platform/commit/40e1afe001d61eafdf13f3621b4b597a0e58a3e3#diff-92fee29683e671b8bc668e3cf4295713d6259f715e3954876049f9de77c0a9ef) to the page `XWiki.XWikiSyntaxMacrosList`. ### References * https://jira.xwiki.org/browse/XWIKI-22030 * https://github.com/xwiki/xwiki-platform/commit/40e1afe001d61eafdf13f3621b4b597a0e58a3e3
