CVE-2024-47334: Zoho Flow SQL Injection Vulnerability

CVE-2024-47334 Overview

CVE-2024-47334 is a SQL Injection vulnerability in the Zoho Flow plugin for WordPress. The flaw stems from improper neutralization of special elements used in a SQL command [CWE-89]. Attackers with high privileges on the target site can inject crafted SQL statements through vulnerable input handling. The issue affects all versions of Zoho Flow up to and including 2.7.1. Exploitation impacts confidentiality with a scope change, allowing an authenticated attacker to access sensitive database contents beyond the plugin's intended boundary. The vulnerability was published to the National Vulnerability Database (NVD) on October 9, 2024.

Critical Impact
Authenticated attackers can extract sensitive data from the WordPress database and cause limited availability impact on adjacent components.

Affected Products

Zoho Flow plugin for WordPress versions up to and including 2.7.1
WordPress sites with the zoho-flow integration plugin installed
Any deployment relying on Zoho Flow releases prior to the patched version

Technical Details for CVE-2024-47334

Vulnerability Analysis

The vulnerability resides in the Zoho Flow WordPress plugin, which integrates WordPress sites with the Zoho Flow automation service. User-supplied input reaches SQL query construction without adequate sanitization or parameterization. An attacker holding elevated WordPress privileges can craft a request that alters the intended query structure. The scope change indicates that the injection influences resources beyond the vulnerable component itself, such as other tables or data owned by different WordPress subsystems.

Root Cause

The root cause is improper neutralization of special characters used in SQL commands [CWE-89]. Input handlers concatenate attacker-controllable values into SQL statements rather than using prepared statements or the WordPress $wpdb->prepare() API. Special characters such as quotes and semicolons pass through unchanged, permitting query manipulation.

Attack Vector

Exploitation occurs over the network against the WordPress admin surface exposed by the plugin. The attacker must already hold high privileges on the WordPress instance, and no user interaction is required. Once authenticated, the attacker submits crafted parameters to a vulnerable plugin endpoint. The injected payload executes in the database context, exposing stored records. Refer to the Patchstack SQL Injection Vulnerability advisory for technical details on the affected parameters.

Detection Methods for CVE-2024-47334

Indicators of Compromise

Unexpected SQL syntax fragments such as UNION SELECT, OR 1=1, or comment sequences in WordPress request logs targeting zoho-flow endpoints
Anomalous database queries originating from the WordPress PHP-FPM worker referencing wp_users, wp_options, or system tables
Administrator or editor sessions issuing plugin requests with unusual parameter payloads

Detection Strategies

Inspect web server access logs for requests to Zoho Flow plugin routes containing encoded SQL metacharacters
Enable MySQL general query logging or slow query logging temporarily to capture malformed queries produced by the plugin
Correlate authenticated administrator activity with subsequent database read spikes to identify data exfiltration behavior

Monitoring Recommendations

Alert on WordPress requests to plugin endpoints containing patterns like ', --, /*, UNION, or SLEEP(
Monitor privileged WordPress account activity, especially newly created administrator or editor accounts
Track outbound traffic volume from the WordPress host to detect bulk data extraction following suspicious plugin activity

How to Mitigate CVE-2024-47334

Immediate Actions Required

Update the Zoho Flow plugin to a version later than 2.7.1 as provided by the vendor
Audit WordPress accounts with administrator or editor roles and remove unused privileged users
Rotate credentials and API keys stored in the WordPress database if compromise is suspected

Patch Information

The vendor released a fixed build subsequent to 2.7.1. Site operators should upgrade the zoho-flow plugin through the WordPress admin dashboard or by replacing the plugin directory with the latest release. Confirm the installed version under Plugins → Installed Plugins after upgrade. Consult the Patchstack advisory for the specific patched release number.

Workarounds

Deactivate the Zoho Flow plugin until the patched version can be installed
Deploy a Web Application Firewall (WAF) rule that blocks SQL metacharacters in requests to /wp-admin/admin-ajax.php targeting Zoho Flow actions
Restrict WordPress administrative access to trusted IP ranges through server-level ACLs

bash

# Configuration example: disable the plugin via WP-CLI until patched
wp plugin deactivate zoho-flow
wp plugin status zoho-flow
