CVE-2019-6804: Rundeck Community Edition Cross-site Scripting Vulnerability

Background

Rundeck Community Edition is an open-source automation tool that helps with job scheduling and execution. It provides a web-based interface for managing workflows and executing tasks. The package 'org.rundeck:rundeck' is a Maven package that includes the Rundeck software. This vulnerability affects versions before 3.0.13 of Rundeck Community Edition.

Vulnerability Detail

The vulnerability identified as CVE-2019-6804 is a Cross-site Scripting (XSS) issue in Rundeck Community Edition. It specifically occurs on the Job Edit page and is related to the 'assets/javascripts/workflowStepEditorKO.js' and 'views/execution/_wfitemEdit.gsp' files. This vulnerability allows an attacker to inject malicious scripts into the web application, which can then be executed by unsuspecting users. The impact of this vulnerability can range from unauthorized access to sensitive information to complete compromise of the affected system.

Workaround

As a temporary workaround, users can implement input validation and output encoding to prevent the execution of malicious scripts. This can be done by sanitizing user input and encoding output to ensure that any potentially dangerous characters are properly escaped. Here is an example of input validation and output encoding in Java:

// Input validation

String userInput =

request.getParameter("input");

if (userInput != null) {
    userInput = userInput.replaceAll("<", "&lt;").replaceAll(">", "&gt;");
}

// Output encoding

String output = "<script>

alert('Hello');

</script>";

output = output.replaceAll("<", "&lt;").replaceAll(">", "&gt;");
response.getWriter().write(output);

Conclusion

In conclusion, the Rundeck Community Edition before version 3.0.13 is vulnerable to a Cross-site Scripting (XSS) issue. This vulnerability can have serious consequences, including unauthorized access and compromise of the affected system. It is crucial to upgrade to version 3.0.13 or later to mitigate this vulnerability. If you need further assistance or support in addressing this vulnerability, please contact DevNack.com.
