Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
