CVE-2025-25968
📋 TL;DR
This vulnerability allows editor-privileged users in DDSN Interactive cm3 Acora CMS version 10.1.1 to access sensitive information like administrator credentials by force browsing endpoints and exploiting the 'file' parameter. Attackers can bypass access controls to read files like cm3.xml, leading to account takeover and privilege escalation. Only systems running the affected CMS version are impacted.
