CVE-2025-34028: Path Traversal Vulnerability in Commvault Command Center Innovation Release 11.38

Overview

The cybersecurity world is ever-evolving, and with each passing day, new vulnerabilities are discovered that pose a significant threat to our existing systems. One such vulnerability, identified as CVE-2025-34028, has been recently detected affecting the Commvault Command Center Innovation Release 11.38. This path traversal vulnerability carries a high severity level and warrants immediate attention as it gives an unauthenticated actor the power to execute remote code, potentially leading to system compromise or data leakage.

How the Exploit Works

This vulnerability stems from a path traversal issue in the Commvault Command Center Innovation Release. A path traversal attack allows an attacker to access directories that they should not be able to access by manipulating a URL or file request to include relative path specifiers. In this case, an unauthenticated actor can upload ZIP files. When these files are expanded by the target server, it results in Remote Code Execution (RCE).
The RCE allows the attacker to execute arbitrary code on the target server, potentially leading to unauthorized access, system compromise, and data leakage. Since no user interaction is required and no privileges are necessary for this exploit, it is highly dangerous and can easily be automated, increasing its potential for widespread damage.

Conceptual Example Code

Please note this is a hypothetical example to illustrate how an attacker might exploit this vulnerability:

POST /upload/zip HTTP/1.1
Host: target.example.com
Content-Type: application/zip
{ "malicious_zip": "payload.zip" }

In this example, the attacker sends a POST request to the upload endpoint of the target server with a malicious ZIP file (‘payload.zip’). Once the server processes this file, the attacker can execute arbitrary code remotely, leading to potential system compromise or data leakage.
It is highly recommended to apply the vendor patch immediately or use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation strategy. By staying vigilant and proactive, we can protect our systems from such high-risk vulnerabilities.
