CVE-2021-40690 - Information Exposure vulnerability

Abstract

All versions of Apache Santuario - XML Security for Java prior to 2.2.3 and 2.1.7 are vulnerable to an issue where the secureValidation property is not passed correctly when creating a KeyInfo from a KeyInfoReference element. This allows an attacker to abuse an XPath Transform to extract any local .xml files in a RetrievalMethod element.

The Apache Santuario - XML Security package is vulnerable to Information Exposure. A remote attacker can exploit this behavior to extract any local .xml files during an XPath transform using the RetrievalMethod element. This would result in the attacker gaining access to otherwise restricted information on an application using this package to implement XML security standards.

The Oxygen XML products incorporates the Apache Santuario - XML Security as a third-party library. This advisory was opened to address the potential impact of this third-party library vulnerability.
