CVE-2021-30638 Open this link in a new tabHow to fix?
Upgrade org.apache.tapestry:tapestry-core
to version 5.6.4, 5.7.2 or higher.
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.
