Python指令碼實現Web漏洞掃描工具
阿新 • • 發佈:2021-01-11
一、使用說明:
1.執行環境:
Linux命令列介面+Python2.7
2.程式原始碼:
Vim scanner//建立一個名為scanner的檔案
Chmod a+xscanner//修改檔案許可權為可執行的
3.執行程式:
Python scanner//執行檔案
若沒有攜帶目標URL資訊,介面輸出幫助資訊,提醒可以可輸入的引數。
引數包括:
--h 輸出幫助資訊
--url 掃描的URL
--data POST請求方法的引數
--cookie HTTP請求頭Cookie值
--user-agent HTTP請求頭User-Agent值
--random-agent 是否使用瀏覽器偽裝
--referer 目標URL的上一層介面
--proxy HTTP請求頭代理值
例如掃描“http://127.0.0.1/dvwa/vulnerabilities/sqli/?id=&Submit=Submit”
Python scanner--url="http://127.0.0.1/dvwa/vulnerabilities/sqli/?id=&Submit=Submit"--cookie="security=low;PHPSESSID=menntb9b2isj7qha739ihg9of1"
輸出掃描結果如下:
結果顯示:
存在XSS漏洞,漏洞匹配漏洞特徵庫“”>.XSS.<””,屬於嵌入標籤外的型別。
存在SQL注入漏洞,目標網站伺服器的資料庫型別為MySQL。
存在BLIND SQL注入漏洞。
二、原始碼:
程式碼驗證過可以執行,我個人推薦用DVWA測試吧。
