Description

The ERP: Complete HR, Accounting & CRM Suite Built for WooCommerce plugin for WordPress is vulnerable to Unrestricted File Type Upload in all versions up to, and including, 1.17.8 via the save_attachments() function. This is due to missing file extension validation and missing path normalization when CRM Email Connect processes inbound IMAP email attachments. This makes it possible for unauthenticated attackers to send a crafted email to the site's configured inbound mailbox with a forged References header matching the plugin's expected pattern and an attachment filename such as `../helper.php`, causing the cron-based IMAP sync job to write attacker-controlled PHP outside of the .htaccess-protected `crm-attachments` directory and into `wp-content/uploads/`. On configurations where PHP executes in uploads, this can lead to remote code execution. Exploitation requires the CRM module and IMAP Email Connect feature to be enabled and configured.
