dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if CF7 Reply Manager plugin is installedNavigate to WordPress admin dashboard > Plugins > Installed Plugins. Look for 'CF7 Reply Manager' or 'Contact Form 7 Reply Manager' in the list. Note the installed version displayed next to the plugin name.Affected if The plugin is installed and active on the WordPress site
-
Verify the installed plugin versionIf the plugin is installed, locate its main PHP file in wp-content/plugins/cf7-reply-manager/ (or similar path). Open the main plugin file and search for a 'Version:' comment or $version variable to confirm the exact version number.Affected if The installed version falls within an unpatched version range and has not been updated to the latest secure release
-
Confirm file upload functionality is enabledCheck WordPress media library settings at wp-admin/options.php (search for 'upload_filetypes' and 'upload_path') and inspect the CF7 Reply Manager settings panel for any file upload or attachment handling configuration.Affected if File uploads are permitted and the plugin's upload handler is active without additional validation controls
-
Inspect upload directories for suspicious filesExamine the wp-content/uploads/ directory (or custom upload path) for newly created files with dangerous extensions such as .php, .phtml, .php5, .php7, .js, .exe, or .sh. Check file creation timestamps corresponding to potential attack periods.Affected if Unexpected executable script files (.php, .phtml, etc.) exist in upload directories that were not intentionally uploaded through legitimate WordPress media functionality
-
Review server-level upload directory protectionsCheck if .htaccess (Apache) or server configuration (Nginx) files in upload directories contain restrictions to prevent execution of uploaded files. Look for 'SetHandler' directives or 'deny from all' rules that block script execution.Affected if Upload directories lack proper restrictions to prevent execution of uploaded files, allowing PHP or other scripts to run if uploaded
The environment is affected if CF7 Reply Manager is installed with an unpatched version and file upload functionality is active without proper server-side execution restrictions on upload directories.
