Synopsis

The Commvault install running on the remote host is affected by multiple vulnerabilities.

Description

The version of Commvault running on the remote web server is 11 prior to 11 SP7. It is, therefore, affected by multiple vulnerabilities:

- A buffer overflow vulnerability exists in the Commvault Edge communication service (cvd). An remote, unauthenticated attacker could achieve arbitrary code execution by sending a specially crafted packet. (CVE-2017-3195)

- A command injection vulnerability exists in CVDataPipe.dll. An unauthenticated, remote attacker can exploit this, via a specially crafted message to CreateProcess, to execute arbitrary commands as SYSTEM. (CVE-2017-18044)

Solution

Upgrade to Commvault v11 SP6 and install hotfix 590, v11 SP7 or later.
