A malicious WebDAV/DavEx server, or an attacker able to intercept the connection, can cause the client to instantiate arbitrary classes from its classpath, which can lead to arbitrary file creation or truncation.
Only applications that use jackrabbit-spi2dav (directly or through jackrabbit-jcr2dav) to connect to a remote repository are affected. Jackrabbit servers are not affected.
Category: unsafe reflection on wire data (HIGH).
This issue affects Apache Jackrabbit: from 2.23.0 through 2.23.5, from 2.22.0 through 2.22.4, from 2.20.0 through 2.20.17.
Users are recommended to upgrade to versions 2.23.6, 2.22.5, or 2.20.18 which fix the issue.
