CVE-2024-7106: Denkgroot Spina CMS CSRF Vulnerability

CVE-2024-7106 Overview

CVE-2024-7106 is a Cross-Site Request Forgery (CSRF) vulnerability in Denkgroot Spina CMS version 2.18.0. The flaw affects an unknown function within the /admin/media_folders endpoint. Attackers can trick authenticated administrators into submitting unintended requests to the affected functionality. The exploit has been publicly disclosed and may be leveraged by remote attackers without authentication or user interaction beyond visiting a crafted page. The vendor was contacted about the disclosure but did not respond. The vulnerability is tracked under VulDB identifier VDB-272431 and is classified under [CWE-352].

Critical Impact
Remote attackers can force authenticated Spina CMS administrators to perform unwanted state-changing operations on the /admin/media_folders endpoint, resulting in unauthorized modifications to media folder resources.

Affected Products

Denkgroot Spina CMS 2.18.0
Spina CMS administrative interface (/admin/media_folders)

Technical Details for CVE-2024-7106

Vulnerability Analysis

The vulnerability resides in the /admin/media_folders administrative endpoint of Spina CMS 2.18.0. The endpoint accepts state-changing requests without validating an anti-CSRF token bound to the administrator session. An attacker who can lure an authenticated administrator to a malicious page can trigger requests that the application processes as legitimate. The attack requires no authentication on the attacker's part because the browser attaches the administrator's session cookies automatically. Public exploit disclosure increases the likelihood of opportunistic abuse against exposed Spina installations.

Root Cause

The root cause is missing or improperly enforced CSRF protection on the /admin/media_folders handler, categorized under [CWE-352]. The application relies on ambient session credentials without verifying the origin or integrity of the request through synchronizer tokens, custom headers, or SameSite cookie policies. Any request the browser can issue while carrying the session cookie is honored by the server.

Attack Vector

Exploitation is remote and network-based. An attacker hosts a page containing a crafted HTML form or JavaScript that issues a POST or GET request to /admin/media_folders on the victim's Spina CMS instance. When an authenticated administrator visits the attacker-controlled page, the browser submits the request with valid session cookies. The server processes the action as if the administrator initiated it. Details are documented in the GitHub Security Collections README and VulDB entry #272431.

No verified proof-of-concept code is included here. The vulnerability mechanism is described in prose per the linked references; see the VulDB CTI record for additional technical context.

Detection Methods for CVE-2024-7106

Indicators of Compromise

Unexpected creation, modification, or deletion of media folders in Spina CMS audit logs without corresponding administrator activity.
HTTP requests to /admin/media_folders with Referer or Origin headers pointing to external, untrusted domains.
Administrator session activity originating from browser contexts where the immediately preceding page load was an unrelated third-party site.

Detection Strategies

Inspect web server and application logs for requests to /admin/media_folders where the Origin or Referer header does not match the Spina CMS host.
Correlate administrator authentication events with subsequent state-changing requests to identify sequences consistent with cross-origin submission.
Deploy a Web Application Firewall (WAF) rule that flags state-changing HTTP methods to /admin/* lacking a valid CSRF token parameter or header.

Monitoring Recommendations

Enable verbose access logging on all /admin/* routes and forward logs to a centralized analytics platform for correlation.
Alert on administrator actions occurring outside expected working hours or from anomalous user-agent strings.
Monitor for repeated 4xx responses from /admin/media_folders, which may indicate probing for CSRF preconditions.

How to Mitigate CVE-2024-7106

Immediate Actions Required

Restrict access to the Spina CMS administrative interface using network-level controls such as VPN or IP allowlisting.
Instruct administrators to log out of Spina CMS sessions when not actively using the application.
Deploy WAF rules that enforce same-origin policy on /admin/media_folders requests until a vendor patch is available.

Patch Information

No vendor patch has been published in the referenced advisories. The vendor did not respond to disclosure attempts according to the VulDB submission. Monitor the Spina project repository and VulDB record #272431 for updates. Consider migrating to a supported CMS version once a fix is released.

Workarounds

Configure session cookies with the SameSite=Strict attribute at the reverse proxy or application server to block cross-site cookie transmission.
Add a reverse-proxy rule requiring the Origin header on state-changing requests to match the Spina CMS canonical hostname.
Require administrators to use a dedicated browser profile or isolated browsing context for Spina CMS administration.
Enable multi-factor authentication on administrator accounts to raise the cost of compromise if session abuse succeeds.

bash

# Example nginx configuration enforcing Origin header validation on admin routes
location /admin/ {
    if ($request_method ~ ^(POST|PUT|DELETE|PATCH)$) {
        if ($http_origin !~* ^https://spina\.example\.com$) {
            return 403;
        }
    }
    add_header Set-Cookie "Path=/; Secure; HttpOnly; SameSite=Strict";
    proxy_pass http://spina_backend;
