CVE-2020-14338  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade xerces:xercesImpl to version 2.12.0.SP03 or higher.

Overview

xerces:xercesImpl is a that is used for high performance, fully compliant XML parsers in the Apache Xerces family.

Affected versions of this package are vulnerable to Improper Input Validation due to the way the XMLSchemaValidator class in the JAXP component of Wildfly enforced the "use-grammar-pool-only" feature. This flaw allows a specially-crafted XML file to manipulate the validation process in certain cases. This issue is the same flaw as CVE-2020-14621, which affected OpenJDK, and uses a similar code.
