Overview:
A Cross Site Scripting (XSS) vulnerability has been discovered in Badaso, a widely used web application platform. This vulnerability, dubbed CVE-2023-38971, exists in Badaso versions ..1 through 2.9.7 and has the potential to be exploited by a remote attacker who can execute arbitrary code by sending a crafted payload through the "rack number" parameter in the add new rack function. This post will delve into the details of this vulnerability and provide related information, including code snippets, links to original references, and exploit details.
Exploit Details
The vulnerability in question occurs due to improper validation of user-supplied input in the "rack number" parameter of the add new rack function. This can be exploited by an attacker by injecting malicious XSS payloads through the vulnerable parameter, enabling them to execute arbitrary code, redirect users to malicious sites, and potentially gain unauthorized access to sensitive data within the web application.
An example of an injected payload within the "rack number" parameter might look like this
<script>alert(document.cookie)</script>
When submitted, this payload would display an alert pop-up containing the victim's cookies, potentially leading to sensitive data exposure.
