CVE-2024-12583: Dynamics 365 Integration RCE Vulnerability

CVE-2024-12583 Overview

CVE-2024-12583 is a Server-Side Template Injection (SSTI) vulnerability in the Dynamics 365 Integration plugin for WordPress. The flaw affects all plugin versions up to and including 1.3.23. The vulnerability resides in the Twig template rendering function, which fails to validate and sanitize user-supplied input. Authenticated attackers with Contributor-level access or above can inject Twig template syntax to execute arbitrary code on the server and read arbitrary files. The issue is tracked under [CWE-1336] (Improper Neutralization of Special Elements Used in a Template Engine).

Critical Impact

Contributor-level attackers can achieve Remote Code Execution and Arbitrary File Read on WordPress sites running the Dynamics 365 Integration plugin, leading to full site compromise.

Affected Products

• WordPress Dynamics 365 Integration plugin versions 1.0 through 1.3.23
• WordPress installations with the integration-dynamics plugin enabled
• Sites granting Contributor-level or higher access to untrusted users

Technical Details for CVE-2024-12583

Vulnerability Analysis

The Dynamics 365 Integration plugin exposes a Twig shortcode handler that renders user-controlled content through the Twig templating engine. The plugin passes shortcode input directly to the Twig render function without escaping template syntax or restricting available template functions. Twig SSTI vulnerabilities allow attackers to break out of the template context and invoke PHP functions, including those that execute shell commands or read filesystem contents.

Because the rendering occurs server-side within the WordPress PHP runtime, successful exploitation grants code execution under the web server account. Attackers can write web shells, exfiltrate database credentials from wp-config.php, or pivot to other systems. The plugin code path is documented in the WordPress Plugin Code Review.

Root Cause

The root cause is missing input validation and sanitization on the Twig render function within src/Shortcode/Twig.php. The plugin instantiates a Twig environment that does not enforce a sandbox policy, so any user with shortcode authoring privileges can submit raw Twig syntax. Contributors in WordPress can create draft posts containing shortcodes, which triggers the unsafe rendering pipeline.

Attack Vector

An attacker authenticates as a Contributor or higher and creates or edits a post containing a malicious Twig shortcode. When the shortcode is rendered through preview or publication, the Twig engine evaluates the injected template expression. Typical payloads abuse Twig filters and PHP function bindings to reach system, exec, or file_get_contents, achieving code execution or arbitrary file disclosure. The EPSS score of 11.92% places this CVE in the 93rd percentile for exploitation likelihood. Refer to the Wordfence Vulnerability Report for additional exploitation context.

Detection Methods for CVE-2024-12583

Indicators of Compromise

• Posts or drafts containing Twig syntax such as {{, }}, {%, or %} authored by Contributor accounts
• Unexpected PHP processes spawned by the WordPress web server user following post preview events
• New or modified files in wp-content/uploads/ or plugin directories that resemble web shells
• Outbound network connections from the WordPress host to unfamiliar IP addresses

Detection Strategies

• Audit post and draft content for shortcodes containing Twig expressions, particularly from non-administrator accounts
• Monitor WordPress audit logs for Contributor-level account creation and post edit activity preceding suspicious server behavior
• Inspect web server access logs for POST requests to wp-admin/post.php followed by GETs returning unexpected response sizes

Monitoring Recommendations

• Enable file integrity monitoring on the WordPress webroot and plugin directories to flag unauthorized file writes
• Correlate WordPress authentication events with process execution telemetry on the underlying host
• Alert on PHP child processes invoking sh, bash, curl, wget, or python from the web server context

How to Mitigate CVE-2024-12583

Immediate Actions Required

• Update the Dynamics 365 Integration plugin to the version released in WordPress Changeset 3210927 or later
• Audit all Contributor, Author, and Editor accounts and remove unused or untrusted users
• Review recently published or drafted posts for Twig syntax and remove malicious content
• Rotate WordPress secret keys, database credentials, and API tokens stored in wp-config.php if compromise is suspected

Patch Information

The vendor addressed the vulnerability in the plugin update referenced by WordPress Changeset 3210927. The fix introduces input sanitization on the Twig render path. Site administrators should apply the patch through the WordPress plugin management dashboard or by deploying the updated package directly.

Workarounds

• Deactivate the Dynamics 365 Integration plugin until the patched version is installed
• Restrict Contributor and higher roles to trusted users only, removing shortcode authoring from untrusted accounts
• Deploy a Web Application Firewall (WAF) rule to block requests containing Twig template syntax in post body parameters

# Update the plugin via WP-CLI
wp plugin update integration-dynamics

# Verify installed version is later than 1.3.23
wp plugin get integration-dynamics --field=version
