Craft CMS is an open source content management system. In affected versions of Craft CMS an unrestricted file extension may lead to Remote Code Execution. If the name parameter value is not empty string('') in the View.php's doesTemplateExist() -> resolveTemplate() -> _resolveTemplateInternal() -> _resolveTemplate() function, it returns directly without extension verification, so that arbitrary extension files are rendered as twig templates. When attacker with admin privileges on a DEV or an improperly configured STG or PROD environment, they can exploit this vulnerability to remote code execution. Code execution may grant the attacker access to the host operating system. This issue has been addressed in version 4.4.6. Users are advised to upgrade. There are no known workarounds for this vulnerability.

GHSA-vqxf-r9ph-cc9c — Craft CMS vulnerable to Remote Code Execution via unrestricted file extension

Affected: Packagist: craftcms/cms

### Summary Unrestricted file extension lead to a potential Remote Code Execution (Authenticated, ALLOW_ADMIN_CHANGES=true)

### Details #### Vulnerability Cause : If the name parameter value is not empty string('') in the View.php's doesTemplateExist() -> resolveTemplate() -> _resolveTemplateInternal() -> _resolveTemplate() function, it returns directly without extension verification, so that arbitrary extension files are rendered as twig templates (even if they are not extensions set in defaultTemplateExtensions = ['html', 'twig']) ```php /** * Searches for a template files, and returns the first match if there is one. * * @param string $basePath The base path to be looking in. * @param string $name The name of the template to be looking for. * @param bool $publicOnly Whether to only look for public templates (template paths that don’t start with the private template trigger). * @return string|null The matching file path, or `null`. */ private function _resolveTemplate(string $basePath, string $name, bool $publicOnly): ?string { // Normalize the path and name $basePath = FileHelper::normalizePath($basePath); $name = trim(FileHelper::normalizePath($name), '/');

// $name could be an empty string (e.g. to load the homepage template) if ($name !== '') { if ($publicOnly && preg_match(sprintf('/(^|\/)%s/', preg_quote($this->_privateTemplateTrigger, '/')), $name)) {…
