Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Dweeves/magmi, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

All versions of MAGMI up to and including version 0.7.24 are vulnerable to CSRF due to the lack of CSRF tokens. RCE (via phpcli command) is possible in the event that a CSRF is leveraged against an existing admin session for MAGMI.
