A significant security vulnerability (CVE-2025-34028) has been discovered in Commvault Command Center Innovation Release, allowing unauthenticated attackers to execute arbitrary code remotely. The vulnerability carries a high CVSS score of 9.0 and impacts version 11.38 of the Command Center installation, potentially leading to complete system compromise if exploited.

Researchers identified a path traversal vulnerability in Commvault Command Center that permits unauthenticated actors to upload malicious ZIP files. When these files are expanded by the target server, it can result in Remote Code Execution (RCE). This flaw allows attackers to manipulate file paths, compromising system integrity and leading to unauthorized access and execution of malicious commands. Security experts noted this vulnerability's severity, emphasizing its potential risks.

The vulnerability impacts Commvault deployments on both Linux and Windows platforms, specifically versions 11.38.0 through 11.38.19. Organizations using these versions are advised to update immediately. Commvault has resolved this issue in version 11.38.20, released on April 10, 2025. For organizations unable to update right away, it is recommended to isolate Command Center installations from external network access until patches can be applied.

Other Commvault Vulnerabilities

In addition to the RCE vulnerability, Commvault has faced other security issues earlier this year, including a Critical Webserver Vulnerability (CV_2025_03_1) and SQL Injection Vulnerability (CV_2025_04_2). These incidents highlight the importance of maintaining updated security patches for data protection platforms.

The Critical Webserver Vulnerability allows remote attackers to execute arbitrary commands, with a high CVSS score of 7.5. Organizations using Commvault products are urged to monitor the updates and apply necessary patches as soon as they are released. For further details, refer to Tenable.

Remote Code Execution (RCE)

Remote code execution (RCE) is a vulnerability that allows attackers to execute arbitrary code from a different location than the system running the application. Known also as code injection and remote code evaluation, RCE can lead to severe consequences such as full system compromise.

RCE vulnerabilities may appear in any software type, regardless of programming language or platform. Commonly exploited vulnerabilities include buffer overflow, deserialization vulnerabilities, SQL injection, and cross-site scripting (XSS). Attackers may use stored RCE to execute code after a delay, storing the payload in a configuration file for later execution.

Mitigation strategies involve eliminating evaluation functions that process user-controlled input, maintaining updated software, and leveraging dynamic application security testing (DAST) tools like Invicti and Acunetix.

For more about detecting RCE vulnerabilities, refer to the software composition analysis (SCA) tools available.
