AI-Generated

Camaleon CMS versions 2.1.1 to 2.9.1 are vulnerable to an authenticated remote code execution flaw that allows users with custom_fields manage permission to execute arbitrary Ruby code. By injecting a malicious expression into the select_eval custom field type, attackers can achieve server-side code execution with the privileges of the web server process. Organizations using affected versions should prioritize patching to mitigate the risk of exploitation.

Original NVD Description

Camaleon CMS versions 2.1.1 through 2.9.1 contains an authenticated remote code execution vulnerability that allows users with custom_fields manage permission to execute arbitrary Ruby code by supplying a malicious expression through the select_eval custom field type. Attackers can store an attacker-controlled Ruby expression in the field options command parameter, which is evaluated via instance_eval within an ERB view whenever a post edit page is rendered, achieving server-side code execution with web server process privileges.
