Overview

org.apache.tapestry:tapestry-core is a Tapestry Core package for Apache Tapestry.

Affected versions of this package are vulnerable to Information Exposure via the context asset handling. It allows an attacker to download files inside WEB-INF if using a specially-constructed URL. This is caused because the fix for CVE-2020-13953 fails to account for the backslash character in the filtering regex, and an attacker is therefore able to list and download web app files from the WEB-INF and META-INF directory using a crafted payload.
