CVE-2024-39410: Adobe Commerce CSRF Vulnerability

CVE-2024-39410 Overview

CVE-2024-39410 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting Adobe Commerce and Magento Open Source. The flaw impacts versions 2.4.7-p1, 2.4.6-p6, 2.4.5-p8, 2.4.4-p9, and earlier. An attacker can trick an authenticated user into loading a crafted page or clicking a malicious link that submits an unauthorized request to the Commerce application. Successful exploitation allows the attacker to bypass CSRF protections and perform minor integrity changes on behalf of the victim user. Adobe addressed the issue in security bulletin APSB24-61.

Critical Impact
Attackers can issue unauthorized state-changing requests through an authenticated victim's browser, modifying data without the user's knowledge.

Affected Products

Adobe Commerce 2.4.7-p1 and earlier (including 2.4.7, 2.4.7-b1, 2.4.7-b2)
Adobe Commerce 2.4.6-p6, 2.4.5-p8, 2.4.4-p9 and all prior patch releases in those branches
Magento Open Source matching the same version ranges

Technical Details for CVE-2024-39410

Vulnerability Analysis

The vulnerability stems from insufficient CSRF protection on one or more Adobe Commerce request handlers. Adobe Commerce typically enforces form key validation on state-changing endpoints, but affected handlers in these builds accept requests without properly validating the anti-CSRF token. An attacker who can lure an authenticated Commerce user to a controlled web page can issue cross-origin requests that the browser automatically authenticates with the victim's session cookies.

The advisory notes that exploitation does not require additional user interaction beyond visiting the attacker-controlled resource. The impact is limited to minor integrity changes performed under the victim's identity. Confidentiality and availability are not affected, and no privileges are required by the attacker on the target application.

Root Cause

The root cause is a missing or improperly enforced CSRF token check on a request handler within the Commerce application. When the server fails to validate the form_key parameter or an equivalent anti-forgery token, it cannot distinguish a legitimate user-initiated request from one forged by a third-party site.

Attack Vector

The attack is network-based and requires user interaction in the form of visiting a malicious page or clicking a crafted link while authenticated to the Commerce storefront or admin interface. The attacker hosts HTML or JavaScript that triggers an automatic POST or GET request to the vulnerable Commerce endpoint. Because the victim's browser attaches the active session cookie, the server processes the request as if the user had initiated it. See the Adobe Security Advisory APSB24-61 for Adobe's technical summary.

Detection Methods for CVE-2024-39410

Indicators of Compromise

Requests to state-changing Commerce endpoints with Referer or Origin headers pointing to untrusted third-party domains.
HTTP POST requests to Commerce actions that lack a valid form_key parameter but return success responses.
Unexpected profile, cart, or configuration changes attributed to legitimate user sessions without corresponding user activity.

Detection Strategies

Enable verbose web server and application logging on Commerce controllers and review for cross-origin referers on sensitive endpoints.
Correlate authentication session identifiers with request origin metadata to identify requests likely sourced from external pages.
Monitor web application firewall (WAF) telemetry for POST requests to Commerce endpoints missing expected anti-CSRF tokens.

Monitoring Recommendations

Alert on anomalous rates of profile updates, address changes, or minor configuration edits originating from the same session within short windows.
Baseline normal Referer and Origin values for authenticated Commerce traffic and flag deviations.
Review Adobe Commerce admin and customer activity logs regularly for actions that users do not recognize.

How to Mitigate CVE-2024-39410

Immediate Actions Required

Apply the Adobe security update referenced in APSB24-61 to all Commerce and Magento Open Source deployments.
Inventory all Commerce instances to confirm patch level and prioritize internet-facing storefronts and admin panels.
Rotate admin and customer session secrets after patching to invalidate any sessions potentially abused prior to remediation.

Patch Information

Adobe released fixed builds for Commerce and Magento Open Source branches 2.4.7, 2.4.6, 2.4.5, and 2.4.4. Administrators should upgrade to the patched release aligned with their current branch as listed in Adobe Security Bulletin APSB24-61. Hosted Adobe Commerce Cloud customers should confirm their environment reflects the updated image.

Workarounds

Restrict access to the Commerce admin interface by IP allowlist or VPN to reduce exposure of authenticated admin sessions to arbitrary web content.
Configure the application and reverse proxy to set SameSite=Lax or SameSite=Strict on session cookies to limit cross-site request inclusion.
Deploy WAF rules that enforce presence of a valid form_key on state-changing Commerce endpoints until patches are applied.

bash

# Configuration example: enforce SameSite on session cookies via Nginx
proxy_cookie_path / "/; HTTPOnly; Secure; SameSite=Lax";
