Package

maven dev.hypera:Dragonfly (Maven)

Affected versions

0.3.0-SNAPSHOT

Description

Dragonfly v0.3.0-SNAPSHOT fails to properly configure the DocumentBuilderFactory to prevent XML external entity (XXE) attacks when parsing maven-metadata.xml files provided by external Maven repositories during "SNAPSHOT" version resolution.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
