CVE-2023-45144Public exploitNetwork attack vector

Unauthenticated code execution via unescaped identityOAuth parameter

Published Oct 16, 2023 · Updated Sep 16, 2024

OAuth Identity XWiki App before 1.6 allows remote attackers to execute code through identityOAuth GET parameters on the login page. LoginUIExtension.vm embeds request.identityOAuth unescaped in an HTML comment, allowing XWiki syntax to invoke the Groovy macro. No authentication or user interaction is required; successful exploitation runs code in the XWiki installation and can read or alter data or interrupt service.
