Affecting org.apache.tapestry:tapestry-core artifact, versions [5.4.0,5.6.4) || [5.7.0,5.7.2)Report new vulnerabilities
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
META-INF directory using a crafted payload.
org.apache.tapestry:tapestry-core to version 5.6.4, 5.7.2 or higher.
