A critical security vulnerability has been identified in the Commvault Command Center, tracked as CVE-2025-34028, which poses a significant risk due to its potential for arbitrary code execution. This flaw, with a CVSS score of 9.0, allows remote attackers to execute code without authentication, potentially leading to a complete compromise of the affected systems. The vulnerability affects versions 11.38.0 through 11.38.19 of the 11.38 Innovation Release and has been addressed in versions 11.38.20 and 11.38.25.
The vulnerability is rooted in an endpoint called "deployWebpackage.do," which can be exploited through a pre-authenticated Server-Side Request Forgery (SSRF). This SSRF can be escalated to execute code by leveraging a ZIP archive containing a malicious .JSP file. The attack sequence involves sending an HTTP request to retrieve and unzip a malicious file, ultimately allowing code execution on the server.
Given the active exploitation of similar vulnerabilities in backup and replication software, it is crucial for organizations using Commvault Command Center to apply the necessary updates and mitigations promptly. The discovery of this flaw highlights the ongoing trend of targeting backup solutions, emphasizing the need for robust security measures in these critical systems.
The primary threat posed by CVE-2025-34028 is the potential for remote code execution without authentication, which could lead to a full system compromise. The vulnerability exploits an SSRF flaw in the "deployWebpackage.do" endpoint, allowing attackers to manipulate server requests and execute arbitrary code. This type of attack can have severe consequences, including unauthorized access to sensitive data and disruption of services.
The vulnerability specifically impacts Commvault Command Center versions 11.38.0 through 11.38.19, with the issue resolved in later versions. The exploit involves a multi-step process where an attacker sends a crafted HTTP request to retrieve a malicious ZIP file, which is then unzipped and executed on the server. This method highlights the sophistication of modern attack vectors targeting backup solutions.
Clients using affected versions of Commvault Command Center may face significant risks, including operational disruptions due to unauthorized code execution and potential data breaches if sensitive information is accessed or exfiltrated. Financial consequences could arise from both direct losses and regulatory fines if compliance requirements are not met.
From a compliance perspective, organizations must be aware that failing to address this vulnerability could lead to audits or penalties under data protection regulations. Ensuring that systems are updated to secure versions is essential to maintaining compliance and protecting organizational reputation.
