CVE-2025-54139: haxcms-php — Exploit & Fix

Description

HAX CMS allows users to manage their microsite universe with a NodeJS or PHP backend. In haxcms-nodejs versions 11.0.12 and below and in haxcms-php versions 11.0.7 and below, all pages within the HAX CMS application do not contain headers to prevent other websites from loading the site within an iframe. This applies to both the CMS and generated sites. An unauthenticated attacker can load the standalone login page or other sensitive functionality within an iframe, performing a UI redressing attack (clickjacking). This can be used to perform social engineering attacks to attempt to coerce users into performing unintended actions within the HAX CMS application. This is fixed in haxcms-nodejs version 11.0.13 and haxcms-php 11.0.8.
