Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied XML input when using the tool XSSFExportToXml to convert user-provided Microsoft Excel documents. A remote attacker can pass a specially crafted XML code to the affected application and read files from the local filesystem or from internal network resources on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
