This vulnerability in AncoraThemes Dentalux arises from improper validation or control of filenames used in PHP include or require statements, leading to PHP Local File Inclusion. This can allow an attacker to include arbitrary local files, potentially resulting in code execution or disclosure of sensitive information. The affected versions include all versions up to and including 3.3. The CVSS 3.1 vector indicates network attack vector, high attack complexity, no privileges required, no user interaction, and impacts on confidentiality, integrity, and availability.

Successful exploitation could lead to the attacker executing arbitrary code or accessing sensitive files on the affected server, compromising confidentiality, integrity, and availability of the system. This could result in full system compromise depending on the server configuration and the files accessible via the inclusion.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should restrict access to vulnerable versions of Dentalux and consider disabling or restricting PHP include/require functionality if possible. Monitor vendor channels for updates and apply patches promptly once released.
