Information Exposure

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.

How to fix Information Exposure?

Upgrade org.apache.tapestry:tapestry-core to version 5.6.4, 5.7.2 or higher.

[5.4.0,5.6.4) [5.7.0,5.7.2)
