CWE-611: Improper Restriction of XML External Entity Reference

Overview

CWE-611 (Improper Restriction of XML External Entity Reference) documents a weakness type used across vulnerability databases and security assessments. Use the sections below for definition, context, and mapped CVEs.

Security impact
Security impact: Depends on product and context; use CVE records, severity scores, and MITRE guidance to prioritize.

Description

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.

Background details

Extended context from the CWE catalog (rendered from MITRE XHTML).

XML documents optionally contain a Document Type Definition (DTD), which, among other features, enables the definition of XML entities. It is possible to define an entity by providing a substitution string in the form of a URI. The XML parser can access the contents of this URI and embed these contents back into the XML document for further processing.

Applicable platforms

Kind Name Class Prevalence OS / CPE
language Not Language-Specific Undetermined
language XML Undetermined
