Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-611: Improper Restriction of XML External Entity Reference, where the product processes an xml document that can contain xml entities with uris that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. In Mei2volpiano, 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

DDMAL MEI2Volpiano 0.8.2 is vulnerable to XML External Entity (XXE), leading to a Denial of Service. This occurs due to the usage of the unsafe 'xml.etree' library to parse untrusted XML input.
