AI-analyzed exploit summary This is a functional proof-of-concept exploit for CVE-2017-18044, a command injection vulnerability in Commvault v11 SP5 and older. It crafts a malicious network packet to execute arbitrary commands on the target system via a TCP connection to port 8400.
Description
A Command Injection issue was discovered in ContentStore/Base/CVDataPipe.dll in Commvault before v11 SP6. A certain message parsing function inside the Commvault service does not properly validate the input of an incoming string before passing it to CreateProcess. As a result, a specially crafted message can inject commands that will be executed on the target operating system. Exploitation of this vulnerability does not require authentication and can lead to SYSTEM level privilege on any system running the cvd daemon. This is a different vulnerability than CVE-2017-3195.

This is a functional proof-of-concept exploit for CVE-2017-18044, a command injection vulnerability in Commvault v11 SP5 and older. It crafts a malicious network packet to execute arbitrary commands on the target system via a TCP connection to port 8400.
This Metasploit module exploits a command injection vulnerability in Commvault Communications Service (cvd.exe) by sending a crafted packet to TCP port 8400, allowing arbitrary command execution as SYSTEM. The exploit leverages PowerShell payload encoding and a malformed message structure to bypass authentication.
