CRITICAL

Apache Commons Jelly < 1.0.1 - XML External Entity Injection via Custom Doctype Entity

Title source: llm
STIX 2.1

Description

During Jelly (xml) file parsing with Apache Xerces, if a custom doctype entity is declared with a "SYSTEM" entity with a URL and that entity is used in the body of the Jelly file, during parser instantiation the parser will attempt to connect to said URL. This could lead to XML External Entity (XXE) attacks in Apache Commons Jelly before 1.0.1.
