Severity:
CVSS 4.0: 6.9 (medium)
CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/S:N
Affected versions:
- Apache Jackrabbit 2.23.0 through 2.23.5
- Apache Jackrabbit 2.22.0 through 2.22.4
- Apache Jackrabbit 2.20.0 through 2.20.17
Description:
— Use of Externally-Controlled Input to Select Classes or Code vulnerability in
Apache Jackrabbit's WebDAV/Davex client.
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.
