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.

Congratulations, you've won a secret backdoor
Hackers exploiting the high-profile Citrix CVE-2019-19781 flaw to compromise VPN gateways are now patching the servers to keep others out.
Researchers at FireEye report finding a hacking group (dubbed NOTROBIN) that has been bundling mitigation code for NetScaler servers with its exploits. In effect, the hackers exploit the flaw to get access to the server, kill any existing malware, set up their own backdoor, then block off the vulnerable code from future exploit attempts by mitigation.
