| Impact | Critical risk (CVSS 9.3, EPSS 63.2%). Commvault manages enterprise backup infrastructure. Compromising the Command Center provides access to all backup data, restoration capabilities, and potentially credentials for backed-up systems. |
| Exploit ScenarioDerived | An attacker uploads a crafted ZIP file as an install package. The path traversal places a JSP web shell in the server's web root. The attacker accesses the web shell, executing commands and accessing all Commvault-managed backup data. |

Commvault Command Center Innovation Release allows unauthenticated remote code execution through path traversal in ZIP file upload handling, enabling malicious JSP deployment on the server.
Earlier versions of this analysis (1)
An unauthenticated path traversal in Commvault Command Center's install package (ZIP) processing allows deploying malicious JSP files for remote code execution.
RemediationAI
Update Commvault. Scan web directories for unauthorized JSP files. Restrict access to the Command Center. Review backup operations for data exfiltration.

Technical ContextAI · show details
The CWE-22 path traversal in the ZIP file expansion allows an attacker to upload a crafted ZIP containing JSP files with path traversal sequences. When the server expands the ZIP, the JSP is placed in the web-accessible directory for execution.

Lifecycle Timeline
3DescriptionCVE.org
The Commvault Command Center Innovation Release allows an unauthenticated actor to upload ZIP files that represent install packages that, when expanded by the target server, are vulnerable to path traversal vulnerability that can result in Remote Code Execution via malicious JSP.
This issue affects Command Center Innovation Release: 11.38.0 to 11.38.20. The vulnerability is fixed in 11.38.20 with SP38-CU20-433 and SP38-CU20-436 and also fixed in 11.38.25 with SP38-CU25-434 and SP38-CU25-438.
Executive ViewAI
Organizations using Commvault Command Center Innovation Release face critical risk from CVE-2025-34028, a path traversal vulnerability rated CVSS 9.3. This could allow attackers to access or modify files outside intended directories, potentially exposing sensitive configuration or credentials. This vulnerability is actively exploited in the wild (KEV-listed) and requires immediate remediation. Immediate patching is required per CISA KEV mandate.
Apply vendor patch. If immediate patching is not feasible: (1) Restrict file upload functionality via WAF; (2) Implement allowlist-based file type validation; (3) Use chroot/containerization to limit filesystem access.

Attack Technique
Path traversal exploits occur when applications use user-controlled input to construct file system paths without proper validation.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
