CVE-2023-24721 has been assigned to this vulnerability, emphasizing its significance and potential impact on affected setups.

This in-depth post will guide you through the vulnerability details, code snippets, and exploit techniques. We'll also provide links to original references and suggest mitigation steps to safeguard your systems from potential breaches.

Vulnerability Details

CVE-2023-24721 is a cross-site scripting (XSS) vulnerability that resides in LiveAction LiveSP v21.1.2. This particular flaw allows hackers to inject malicious code into the app, manipulating its behavior and leading to various attack scenarios such as account takeover, session hijacking, or phishing attempts.

The vulnerability appears in the vulnerable parameter of the web application, allowing attackers to inject malicious payload and execute potentially dangerous actions. Upon successful exploitation, arbitrary web scripts or HTML are executed, causing potentially disastrous consequences.

Code Snippet

A sample of the code snippet revealing the vulnerability is provided below. Note that the actual implementation in your environment may differ, so take this as a reference rather than a copy-paste solution.

<script>
var vulnerableParam = 'PARAM'; // Replace PARAM with the vulnerable parameter in your setup.
var payload = '<script>alert("XSS Attack!")</script>';
var exploit = vulnerableParam + payload;
document.write(exploit);
</script>

In this code snippet, the vulnerableParam variable is assigned the value of the affected parameter. The payload variable contains a simple XSS attack (an alert displaying "XSS Attack!") as an example. The malicious script is then concatenated with the vulnerableParam variable, producing the exploit variable. The exploit variable is then written to the document, resulting in the execution of the malicious code.
