CVE-2024-7717: WP Events Manager SQL Injection Vulnerability

CVE-2024-7717 Overview

CVE-2024-7717 is a time-based SQL injection vulnerability in the WP Events Manager plugin for WordPress, developed by Thimpress. The flaw affects all versions up to and including 2.1.11 and stems from insufficient escaping of the order parameter combined with inadequate query preparation. Authenticated attackers holding Subscriber-level access or higher can append arbitrary SQL statements to existing queries. Successful exploitation allows extraction of sensitive database contents, including credentials and personally identifiable information.

Critical Impact
Authenticated attackers with minimal privileges can exfiltrate arbitrary data from the WordPress database, including password hashes and session tokens.

Affected Products

Thimpress WP Events Manager plugin for WordPress, versions up to and including 2.1.11
WordPress installations with the vulnerable plugin activated
Sites permitting Subscriber-level or higher user registration

Technical Details for CVE-2024-7717

Vulnerability Analysis

The vulnerability resides in the class-wpems-post-types.php file of the WP Events Manager plugin. The plugin accepts a user-supplied order parameter and concatenates it directly into a SQL query without sufficient escaping or use of parameterized statements. This classifies the flaw under CWE-89, Improper Neutralization of Special Elements used in an SQL Command.

Because direct output of the query results is not returned to the attacker, exploitation relies on time-based inference. Attackers inject payloads that use SQL functions such as SLEEP() or BENCHMARK() to induce measurable delays. By observing response times, an attacker reconstructs database contents one bit at a time.

Root Cause

The plugin builds an ORDER BY clause using unsanitized input from the order HTTP parameter. WordPress's $wpdb->prepare() function is not applied correctly to this segment of the query. Values passed to ORDER BY cannot be parameterized as bound values, so developers must allowlist accepted keywords. The plugin fails to enforce such an allowlist, permitting injection of arbitrary SQL fragments.

Attack Vector

Exploitation requires an authenticated account with Subscriber-level access, which many WordPress sites grant through open registration. The attacker submits a crafted HTTP request containing malicious SQL syntax in the order parameter to an endpoint that invokes the vulnerable query. Time-based blind injection payloads then enumerate database schema and extract row data through response timing analysis.

No verified public proof-of-concept code has been released. For source-level details, review the WordPress Events Manager plugin code and the Wordfence vulnerability analysis.

Detection Methods for CVE-2024-7717

Indicators of Compromise

HTTP requests to WordPress endpoints containing SQL keywords such as SLEEP, BENCHMARK, UNION, or SELECT inside the order parameter.
Repeated authenticated requests from a single Subscriber account with unusually long or varied server response times.
Web server access logs showing systematic parameter fuzzing patterns against event listing URLs.
Unexpected database read activity from the wp_users or wp_usermeta tables originating from the plugin's query paths.

Detection Strategies

Deploy a web application firewall rule that inspects the order query parameter for SQL syntax and time-delay functions.
Enable WordPress query logging or a plugin-level audit trail to capture SQL statements executed on behalf of low-privilege accounts.
Correlate authentication events with anomalous query latency to identify blind injection attempts.

Monitoring Recommendations

Track HTTP response time distributions for authenticated requests to WP Events Manager endpoints and alert on statistical outliers.
Monitor Subscriber-level accounts for behavior inconsistent with normal user activity, such as rapid or scripted request patterns.
Review WordPress debug.log and database slow-query logs for statements containing ORDER BY fragments that include function calls.

How to Mitigate CVE-2024-7717

Immediate Actions Required

Upgrade the WP Events Manager plugin to version 2.2.0 or later, which addresses the injection flaw.
Audit all WordPress user accounts and remove or disable unused Subscriber-level accounts.
Rotate WordPress administrator credentials, secret keys, and any API tokens stored in the database if exploitation is suspected.
Restrict new user registration until the plugin is patched.

Patch Information

Thimpress released a fix in WP Events Manager version 2.2.0. Review the patched source file and the Wordfence vulnerability analysis for remediation details. Administrators should apply the update through the WordPress plugin manager and verify the installed version reports 2.2.0 or higher.

Workarounds

Deactivate the WP Events Manager plugin until the upgrade to version 2.2.0 or later is completed.
Apply WAF rules that block requests containing SQL keywords in the order parameter targeting WordPress endpoints.
Disable open user registration under Settings > General to reduce the pool of authenticated attackers.
Enforce strong password policies and multi-factor authentication for all WordPress accounts, including Subscribers.

bash

# Configuration example: disable open registration and update the plugin via WP-CLI
wp option update users_can_register 0
wp plugin update wp-events-manager --version=2.2.0
wp plugin status wp-events-manager
