Remote Code Execution via unrestricted file extension in Craft CMS

CVE-2023-32679

Summary

Craft CMS, an open-source content management system by Pixel & Tonic, is vulnerable to a Remote Code Execution exploit due to an unrestricted file extension issue. In specific versions, the function responsible for verifying template existence does not adequately check file extensions when the 'name' parameter is provided. This flaw allows an attacker with admin privileges in a development or misconfigured environment to execute arbitrary code on the server, potentially granting access to the host operating system. Users should upgrade to version 4.4.6 or later to mitigate this vulnerability, as there are no known workarounds.
