How to detect it
Nuclei template (active check)
Commvault - Path Traversal
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.
Name and description quoted from the template, written by VEDAS.
The template sends 1 request (POST /commandcenter/deployWebpackage.do); it confirms through an out-of-band callback (interactsh), so the scanner must be able to receive it; it decides using dsl matchers. Severity in the template: critical. Marked as not yet verified against a live vulnerable target.
