CVE-2024-29184

Summary

CVE-2024-29184 is a Stored Cross-Site Scripting (XSS) vulnerability affecting FreeScout, a self-hosted help desk and shared mailbox application. The issue lies in the Signature Input Field prior to version 1.8.128, where user input was not properly sanitized, allowing malicious scripts to be stored and executed when other users access the affected page. The attacker can exploit this by uploading a JavaScript (JS) file to the server via a POST request to the /conversation/upload endpoint, subsequently bypassing the Content Security Policy (CSP) and executing XSS attacks. The impact is severe, enabling attackers to compromise the application, steal sensitive information, or elevate privileges, leading to potential data breaches or unauthorized access. Version 1.8.128 includes a patch for this vulnerability.
