CVE-2024-55877 – XWiki allows remote code execution from account through macro descriptions and XWiki.XWikiSyntaxMacrosList

https://notcve.org/view.php?id=CVE-2024-55877

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. • https://github.com/xwiki/xwiki-platform/commit/40e1afe001d61eafdf13f3621b4b597a0e58a3e3 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-2r87-74cx-2p7c https://jira.xwiki.org/browse/XWIKI-22030 • CWE-96: Improper Neutralization of Directives in Statically Saved Code ('Static Code Injection') •
