CVE-2025-34028 is a critical vulnerability affecting the Commvault Command Center Innovation Release. With a CVSS score of 9.3, this vulnerability allows an unauthenticated actor to upload ZIP files that, when extracted by the target server, can be exploited through a path traversal vulnerability leading to remote code execution via malicious JSP. This flaw impacts versions 11.38.0 to 11.38.20 and has been addressed in version 11.38.20 with specific updates and also in version 11.38.25.
The urgency of addressing this vulnerability cannot be overstated due to its potential for severe impacts. Organizations are strongly advised to prioritize patching immediately to mitigate risks associated with this critical flaw, which has already been recognized in the Known Exploited Vulnerabilities (KEV) catalog.
Commvault's Command Center is widely used for data management, making this vulnerability particularly concerning for organizations relying on its functionality. Attackers may leverage this vulnerability to execute arbitrary code, which could lead to unauthorized access and potentially catastrophic ramifications for data integrity and availability.
In light of the critical nature of this vulnerability, organizations should not only patch the affected systems but also review their security posture to prevent similar vulnerabilities in the future.
Vulnerability Details
The official CVE description states that the Commvault Command Center Innovation Release is vulnerable due to its handling of ZIP file uploads that can lead to path traversal vulnerabilities. This occurs when an attacker exploits the application’s file upload process to gain access to restricted areas of the file system.
The CVSS score of 9.3 reflects a critical severity level, indicating a high potential for exploitability. Organizations must assess their deployment of Commvault, particularly those using versions prior to the patches implemented in 11.38.20 and 11.38.25.
Technical Analysis
The root cause of CVE-2025-34028 stems from improper validation of user inputs during the file upload process, specifically allowing ZIP files to include paths that can be traversed. The attack vector is classified as network-based, with a low attack complexity since no special privileges or user interaction is required to exploit the vulnerability.
The vulnerability impacts confidentiality, integrity, and availability, with high severity for both integrity and availability impacts, as attackers could execute arbitrary code and manipulate the server environment.
Risk & Impact Analysis
Risk to organizations includes unauthorized remote code execution, which could lead to data breaches, service disruptions, and significant reputational damage. The blast radius is extensive, as the vulnerability can affect any organization using the vulnerable versions of Commvault, potentially allowing attackers to manipulate sensitive data or disrupt operations.
Given the critical nature of this vulnerability and its high profile status, organizations should prioritize patching immediately. Failure to address this vulnerability could result in severe consequences, including legal ramifications and loss of customer trust.

Affected Versions
The affected versions of Commvault Command Center range from 11.38.0 to 11.38.20. Organizations should ensure they upgrade to version 11.38.20 or later, specifically with updates SP38-CU20-433 and SP38-CU20-436, or to 11.38.25 with SP38-CU25-434 and SP38-CU25-438 to mitigate this vulnerability effectively.
Mitigation & Remediation
Organizations should apply the latest patches provided by Commvault to remediate this vulnerability. It is critical to upgrade to the fixed versions as outlined. Additionally, organizations may also consider implementing network controls to prevent unauthorized access and monitor for anomalous activities that could indicate exploitation attempts. For detailed guidance, organizations can refer to penetration testing services to evaluate their security posture against such vulnerabilities.
Detection Guidance
To detect potential exploitation attempts, organizations should implement logging of file uploads, particularly monitoring for ZIP files being uploaded to the Command Center. Behavioral anomalies should be analyzed, and network signatures should be established to identify unauthorized access patterns. Additionally, monitoring for changes in the system that could indicate exploitation is crucial.
AppSecure Threat Intelligence Insight
This vulnerability highlights the ongoing challenges with file upload mechanisms and their security. As organizations increasingly rely on web applications for critical functions, ensuring robust security controls in such areas is paramount. Security teams should learn from this incident to bolster their application security practices, particularly around input validation and file handling. For additional insights into improving security practices, organizations may refer to vulnerability management program design, penetration testing methodology, and continuous security testing strategies to enhance overall security posture.
