CVE-2024-2354 Overview
CVE-2024-2354 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] in Dreamer CMS version 4.1.3. The flaw resides in the /admin/menu/toEdit endpoint, where the id parameter is processed without adequate anti-CSRF protection. An unauthenticated remote attacker can craft a malicious web page that, when visited by an authenticated administrator, triggers unintended state-changing actions in the CMS. The vendor, iteachyou, was reportedly contacted about the disclosure but did not respond. Public exploit documentation is available through third-party repositories.
Critical Impact
Successful exploitation allows attackers to modify administrative menu entries in Dreamer CMS by tricking an authenticated administrator into visiting a malicious page, resulting in unauthorized data integrity impact.

Technical Details for CVE-2024-2354
Vulnerability Analysis
The vulnerability affects the administrative menu editing function exposed at /admin/menu/toEdit in Dreamer CMS 4.1.3. The endpoint accepts an id parameter but lacks a per-request CSRF token or equivalent origin validation. An attacker who lures an authenticated administrator to a hostile page can cause the browser to submit forged requests using the victim's active session. This produces integrity impact on stored administrative menu data without requiring credential theft.
Root Cause
The root cause is missing CSRF protection on a state-changing administrative endpoint. Dreamer CMS does not validate that requests to /admin/menu/toEdit originate from a legitimate first-party form submission. There is no synchronizer token, no SameSite cookie enforcement documented, and no verification of the Origin or Referer headers on this route.
Attack Vector
Exploitation requires user interaction: an authenticated administrator must visit an attacker-controlled page or click a malicious link while logged into Dreamer CMS. The attacker page issues a cross-origin request to /admin/menu/toEdit containing a chosen id value. The victim's browser automatically attaches the administrator session cookie, and the server processes the forged action. No prior authentication is required by the attacker, and the attack can be launched remotely over the network.
A proof-of-concept has been publicly disclosed. See the GitHub BugHub CSRF Document and the VulDB Entry #256314 for reference material.
Detection Methods for CVE-2024-2354
Indicators of Compromise
- Unexpected modifications to administrative menu records within Dreamer CMS.
- HTTP requests to /admin/menu/toEdit originating with third-party Referer headers or missing Origin headers.
- Administrator-session requests that immediately follow navigation to unfamiliar external domains.
Detection Strategies
- Inspect web server and application logs for POST or GET requests to /admin/menu/toEdit where the Referer or Origin header does not match the CMS host.
- Correlate administrator authentication events with subsequent menu edit actions to identify anomalous edit sequences.
- Deploy a Web Application Firewall (WAF) rule that flags administrative endpoints receiving requests without a valid CSRF token.
Monitoring Recommendations
- Enable audit logging for all /admin/* routes and forward events to a central SIEM for correlation.
- Alert on menu configuration changes that occur outside of documented change windows.
- Track browser session cookies and administrator IP address consistency to spot session-riding activity.
How to Mitigate CVE-2024-2354
Immediate Actions Required
- Restrict access to the Dreamer CMS administrative interface using IP allow-listing or a VPN.
- Instruct administrators not to browse untrusted sites while authenticated to the CMS.
- Terminate active administrator sessions after use and avoid persistent logins.
- Review recent changes to administrative menus for unauthorized modifications.
Patch Information
No vendor advisory or official patch is referenced in the NVD entry for CVE-2024-2354. The disclosure notes that the vendor did not respond to outreach. Organizations running Dreamer CMS 4.1.3 should monitor the VulDB CTI #256314 entry and the vendor's official channels for any future update, or consider migrating away from the affected version.
Workarounds
- Configure session cookies with the SameSite=Strict attribute at the reverse proxy to block cross-site cookie transmission.
- Deploy a WAF rule that rejects requests to /admin/menu/toEdit lacking a valid same-origin Referer header.
- Isolate the CMS admin panel on an internal network segment not reachable from user browsing environments.
- Require administrators to use a dedicated browser or browser profile solely for CMS administration.
