Detailsinfo

A vulnerability was found in Printcart Web to Print Product Designer for WooCommerce Plugin up to 2.5.2 on WordPress and classified as critical. Affected by this issue is the function store_design_data of the component Path Validation Handler. The manipulation of the argument nbd_item_key with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The Printcart Web to Print Product Designer for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 2.5.2 This is due to insufficient path validation in the store_design_data() function, which constructs a filesystem path from the user-supplied 'nbd_item_key' POST parameter sanitized only with sanitize_text_field() — which does not strip path traversal sequences — and then passes that path directly to Nbdesigner_IO::delete_folder() and PHP's rename(). The nonce protecting the nbd_save_customer_design AJAX action is freely obtainable by unauthenticated users via the nbd_check_use_logged_in endpoint. This makes it possible for unauthenticated attackers to delete arbitrary files on the affected site's server which may make remote code execution possible.
