Description

This module exploits a directory traversal vulnerability (CVE-2019-19781) within Citrix ADC (NetScaler). It requests the smb.conf file located in the /vpns/cfg directory by issuing the request /vpn/../vpns/cfg/smb.conf. It then checks if the server is vulnerable by looking for the presence of a "[global]" directive in smb.conf, which this file should always contain.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
