Common Weakness Enumeration

CWE-611

Allowed

Improper Restriction of XML External Entity Reference

Abstraction: Base · Status: Draft

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.

1712 vulnerabilities reference this CWE, most recent first.

Summary
XXE vulnerability in Jenkins Liquibase Runner Plugin
Details

Jenkins Liquibase Runner Plugin 1.4.5 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers able to provide Liquibase changesets evaluated by the plugin to have Jenkins parse a crafted XML file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Jenkins Liquibase Runner Plugin 1.4.7 no longer parses Liquibase changesets.

Details

In Eclipse Kura versions up to 4.0.0, the Web UI package and component services, the Artemis simple Mqtt component and the emulator position service (not part of the device distribution) could potentially be target of XXE attack due to an improper factory and parser initialisation.

Mitigation
Implementation System Configuration

Many XML parsers and validators can be configured to disable external entity expansion.

CAPEC-221: Data Serialization External Entities Blowup

This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
