How to Fix CVE-2025-34028: Critical Path Traversal Vulnerability in Commvault Command Center with Remote Code Execution Risk?
Commvault Command Center is facing a critical security flaw. This article aims to equip security professionals with the knowledge and steps necessary to mitigate CVE-2025-34028, a path traversal vulnerability that could lead to remote code execution. Understanding the vulnerability, its impact, and the remediation strategies is crucial for maintaining the security and integrity of your Commvault environment. We will delve into the specifics of the vulnerability and offer actionable guidance to safeguard your systems.
A Short Introduction to Commvault Command Center
Commvault Command Center is a comprehensive data management platform that provides backup, recovery, archiving, and eDiscovery capabilities. It offers a centralized management console for administering data across various environments, including on-premises, cloud, and hybrid infrastructures. The Command Center is designed to streamline data protection operations and ensure data availability and compliance. Its web-based interface allows administrators to configure and monitor data management tasks from a single pane of glass.
Summary of CVE-2025-34028
CVE ID: CVE-2025-34028
Description: An unauthenticated path traversal vulnerability that allows attackers to upload malicious ZIP files, leading to remote code execution.
CVSS Score: 10.0 (Critical)
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:H/A:H
This critical vulnerability stems from the Commvault Command Center's improper handling of pathname restrictions. An unauthenticated attacker can exploit this by uploading specially crafted ZIP files. When the server expands these files, a path traversal vulnerability is triggered, potentially allowing the execution of arbitrary code through malicious JSP files. The highest level of severity is attributed to the risk of remote, unauthorized access to the system due to the flaw.
Impact of CVE-2025-34028
The impact of CVE-2025-34028 is significant due to its high CVSS score and ease of exploitation. Attackers can remotely exploit this vulnerability without any authentication, meaning no valid user credentials are required. The vulnerability requires no user interaction, making it easier to exploit. A successful exploit can lead to a complete compromise of the Commvault Command Center, enabling unauthorized file manipulation, system takeover, and potential compromise of system integrity, availability, and partial confidentiality. This can disrupt operations, lead to data breaches, and damage an organization's reputation.

How to Check Your Product is Vulnerable?
To determine if your Commvault Command Center installation is vulnerable, follow these steps:
Check the Version: Log in to the Commvault Command Center and navigate to the "About" section or the system information page to identify the installed version.
Compare with Affected Versions: If the version falls within the range of 11.38.0 to 11.38.19, your installation is vulnerable.
Verify Installed Updates: If running version 11.38.20 or 11.38.25, check the Server listing page and select each Command Center installation to verify that the additional updates (SP38-CU20-433, SP38-CU20-436, SP38-CU25-434, SP38-CU25-438) are listed under Additional Updates.
How to Fix CVE-2025-34028?
The primary remediation strategy is to update the Commvault Command Center to a patched version. Follow these steps to mitigate the vulnerability:
Upgrade to a Fixed Version: Upgrade to version 11.38.20 or 11.38.25 (or later) along with the specified additional updates (SP38-CU20-433, SP38-CU20-436, SP38-CU25-434, SP38-CU25-438). You can download the latest updates from the Downloading Software On Demand page.
Workaround (If Patching is Not Immediately Feasible): If updating is not immediately possible, isolate the Command Center installation from external network access.
Additional Security Measures:
Implement strict file upload validation to prevent the upload of malicious ZIP files.
Monitor and restrict unauthorized file uploads.
Validate and sanitize all file upload mechanisms.
By applying these fixes and implementing the recommended security measures, you can effectively mitigate the risk posed by CVE-2025-34028 and protect your Commvault Command Center environment from potential exploitation.
