Commvault Command Center Path Traversal Vulnerability
Commvault · Command Center
Commvault Command Center contains a path traversal flaw in its handling of uploaded ZIP install packages, which the server expands without restricting where files are written. An unauthenticated remote attacker who can reach the Command Center service can upload a crafted ZIP archive, and no user interaction or prior authentication is required, so the attacker can write a malicious JSP file to a location the server will execute, achieving remote code execution.
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.
