Curl Usage with Google Dev Tools – First steps
To copy Curl Syntax for bash Shell do the following
- Load your inital WebSite a first time
- Press F12 to attach/open Google Dev Tools
- Reload your Page
- Navigate to Network Tab
- Right click the desired API call
- Select “Copy” -> “Copy as cURL (bash)”
| Retrieve the cURL bash Command using Google Dev Tools |
 “;[/insert_php] |
Run our first cURL command
- Paste the cURL command to a bash Shell
- Add -v switch to get HTTP header dumped
- redirect stderr by adding: 2>&1

HTTP Status of our first cURL request
- The Website gets loaded sucessfuly -> HTTP/1.1 200 OK
- The Website Content-Length is: 8471
- The Website uses cookies: JSESSIONID
- The Website uses https protocol
Use the Google Dev to understand the Login Logic

index.action loads 2 javascript files
Processing and Validation of Login Form
var verifyResult;
$("#login").click(function() {
if (!allowLogin) {
jAlert(browserMessage, Message.alarm_info, '{"' + Message.sur + '":"OK"}');
clearPassword();
return;
}
var userName = $.trim($("#userName").val());
var password = $("#password").val();
if (!loginValidate(userName, password)) {
clearPassword();
return;
}
var showVerifyCode = document.getElementById("verifyCode_tr").style.display;
comitLogin(userName, password);
});
- For our cURL tutorials we can skip this Step as we already know username / password
- Let’s review the JS function comitLogin()
Login Code implemented via sync. AJAX POST resquest
function comitLogin(userName, password) {
if ($("#veryCode").is(":visible")) {
if (!validateVCodeLength()) {
clearPassword();
return;
}
}
var code = $("#veryCode").attr("value");
$.ajax({
url : basePath + "security!login.action",
type : "POST",
async : false,
dataType : "json",
data : {
"userName" : userName,
"password" : password,
dateTime : new Date().getTime(),
"veryCode" : code
},
cache : false,
beforeSend:function (XMLHttpRequest)
{
//let go
},
success : function(res) {
clearPassword();
$("#pass1").val("");
$("#pass2").val("");
$("#loginErrorMsg").html("")
$("#loginErrorMsg2").html("");
if (res.retMsg == "op.successfully") {
window.location.href = newPath + "securitys!tologin.action";
return;
} else if (res.retMsg == "op.update") {
$("#loginView").hide();
....
- For sending username,password,date and verificationCode a POST request is used
- The remote function to be called is security!login.action
- A successfull login should return: “op.successfully”
- After successfull login a page redirection is triggered to: securitys!tologin.action
Step 1: Implement the Website JavaScript Login with bash/cURL
| Set breakpoint in AJAX POTS when returning from AJAX POST request |
| “;[/insert_php] |
| Login the Page – Login process is paused |
| “;[/insert_php] |
| Verify Response and Request Headers |
| “;[/insert_php] |
- For further processing we need to use the JSESSIONID returned by the Response header
Paste above Output to a Bash Shell

What we learned in Step 1
- A sucessful login returns message {"retMsg":"op.successfully"} and a new JSESSIONID
- This JSESSIONID need to be used for subsequent HTTP/AJAX request
- Note: At this stage we are able to attack this page using a brute FORCE methode
Step 2: Implement the Login Redirect using bash/cURL
- After as succesfull login the page is redirectet to securitys!tologin.action
- For the complete JS Code review Step 1
if (res.retMsg == "op.successfully") {
window.location.href = newPath + "securitys!tologin.action";
return;
Use Google Dev tools to extract cURL bash Code
- Login to the WebSite
- Navigate to Network Tab
- Locate the securitys!tologin.action Request
- Select “Copy” -> “Copy as cURL (bash)”

Test script WRLogin2.sh to simulate the Page redirect
- WRlogin2.sh extracts the X-CSRF-TOKEN from HTML Meta Tags
- Together with JSESSIONID return from WRLogin.sh this Info is used to access our target WEBSite
$ ./WRlogin2.sh
--------------------------------------------------------------------------------------------------------
-> URL : https://52.58.164.53:8443/securitys!tologin.action

Run: $ export csrf_token="X-CSRF-TOKEN: 218df123-fa18-44ba-8f3f-2dbc378e987c"
--------------------------------------------------------------------------------------------------------
Step 3: Finally Implement the Page Access using bash/cURL
- For this script we need: JSESSIONID returned from WRlogin.sh
- X-CSRF-TOKEN retuned from WRlogin2,sh
Follow the steps from above to extract the cURL bash command
