CVE-2024-2284 Overview
CVE-2024-2284 is a stored cross-site scripting (XSS) vulnerability in boyiddha Automated-Mess-Management-System version 1.0. The flaw resides in the /member/chat.php file within the Chat Book component. Attackers manipulate the msg parameter to inject arbitrary script content that executes in the browsers of other users viewing the chat. The attack is remotely exploitable over the network and requires user interaction to trigger the payload. The exploit has been publicly disclosed, increasing the likelihood of opportunistic abuse. The vendor was contacted prior to disclosure but did not respond, and no official patch is available.
Critical Impact
Authenticated attackers can inject persistent JavaScript payloads into chat messages, enabling session hijacking, credential theft, and unauthorized actions in victim browser contexts.

Technical Details for CVE-2024-2284
Vulnerability Analysis
The vulnerability is a stored cross-site scripting flaw classified under [CWE-79], Improper Neutralization of Input During Web Page Generation. The /member/chat.php endpoint accepts user-supplied content through the msg parameter without sanitizing or encoding HTML and JavaScript metacharacters. The submitted message is persisted in backend storage and later rendered to any member viewing the Chat Book. When rendered, the browser interprets injected <script> tags or event handler attributes as executable code within the application origin.
Because the payload is stored, every subsequent viewer of the affected chat thread is impacted without needing to click a crafted link. The attack requires only standard member-level access to the chat interface, lowering the barrier for exploitation.
Root Cause
The root cause is missing output encoding and input validation in the chat message handler. The application concatenates the raw msg value directly into the HTML response, allowing arbitrary markup to break out of the intended text context. There is no Content Security Policy enforcement to restrict inline script execution as a defense-in-depth measure.
Attack Vector
An attacker authenticates to the Automated-Mess-Management-System as a member and submits a chat message containing an XSS payload through the msg parameter of /member/chat.php. The payload is stored and rendered to all members viewing the chat. When a victim loads the page, the script executes in their session context, enabling cookie theft, forced actions through the member portal, or redirection to attacker-controlled infrastructure. A public proof of concept is available in the GitHub PoC for XSS repository, and additional context is documented in the VulDB entry #256051.
Detection Methods for CVE-2024-2284
Indicators of Compromise
- Chat records in the msg field containing <script>, onerror=, onload=, javascript:, or encoded variants such as <script>.
- Outbound HTTP requests from member browsers to unexpected domains shortly after loading /member/chat.php.
- Unusual session activity or account changes immediately following chat views by administrators.
Detection Strategies
- Review web server access logs for POST requests to /member/chat.php containing HTML or JavaScript metacharacters in the msg parameter.
- Deploy a web application firewall rule to flag payloads matching common XSS signatures targeting the chat endpoint.
- Audit the chat database table for stored messages containing script tags, event handlers, or data URIs.
Monitoring Recommendations
- Enable browser-side Content Security Policy violation reporting to capture inline script execution attempts.
- Correlate authentication events with chat submission activity to identify accounts posting repeated suspicious payloads.
- Monitor administrator and privileged member session activity for anomalous requests originating from chat page contexts.
How to Mitigate CVE-2024-2284
Immediate Actions Required
- Restrict or disable the Chat Book component until the application code is remediated.
- Purge any stored chat messages containing script tags or JavaScript event handlers from the database.
- Rotate session cookies and credentials for members who viewed potentially malicious chat threads.
- Place the application behind a web application firewall configured with XSS filtering rules.
Patch Information
No official vendor patch is available. The maintainer did not respond to disclosure attempts according to the VulDB record. Organizations running Automated-Mess-Management-System 1.0 should treat the application as unsupported and consider migrating to a maintained alternative. If the deployment must remain in use, apply source-level fixes by HTML-encoding the msg parameter output using a function such as htmlspecialchars($msg, ENT_QUOTES, 'UTF-8') before rendering, and validate input length and character set on the server side.
Workarounds
- Implement a reverse proxy that strips or encodes HTML metacharacters in requests to /member/chat.php.
- Enforce a strict Content Security Policy header disallowing inline scripts and restricting script sources.
- Limit chat access to a minimum set of trusted users and audit messages manually until remediation is complete.
- Isolate the application on a dedicated host and segment it from administrative networks to limit blast radius.
