Overview

CVE-2016-9182 is a high-severity vulnerability. It was published on November 4, 2016 and has a CVSS 3.0 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.0 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Exponent CMS 2.4 uses PHP reflection to call a method of a controller class, and then uses the method name to check user permission. But, the method name in PHP reflection is case insensitive, and Exponent CMS permits undefined actions to execute by default, so an attacker can use a capitalized method name to bypass the permission check, e.g., controller=expHTMLEditor&action=preview&editor=ckeditor and controller=expHTMLEditor&action=Preview&editor=ckeditor. An anonymous user will be rejected for the former but can access the latter.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
