CVE-2025-24767: TicketBAI Facturas WooCommerce SQL Vuln

CVE-2025-24767 Overview

CVE-2025-24767 is a critical Blind SQL Injection vulnerability affecting the TicketBAI Facturas para WooCommerce WordPress plugin developed by facturaone. The vulnerability exists due to improper neutralization of special elements used in SQL commands (CWE-89), allowing attackers to execute arbitrary SQL queries against the underlying database without requiring authentication.

This plugin is designed for Spanish businesses to comply with TicketBAI invoicing requirements in WooCommerce environments. The SQL injection flaw can be exploited remotely over the network, potentially exposing sensitive business and customer data stored in WordPress databases.

Critical Impact

Unauthenticated attackers can exploit this blind SQL injection to extract sensitive database contents including customer information, order details, financial records, and WordPress credentials without user interaction.

Affected Products

• TicketBAI Facturas para WooCommerce plugin versions through 3.19
• WordPress installations running the vulnerable wp-ticketbai plugin
• WooCommerce stores utilizing TicketBAI invoicing functionality

Technical Details for CVE-2025-24767

Vulnerability Analysis

This vulnerability is classified as a Blind SQL Injection (CWE-89), which occurs when user-supplied input is incorporated into SQL queries without proper sanitization or parameterization. The "blind" nature of this injection means that the application does not display database errors or query results directly to the attacker. Instead, attackers must infer information through application behavior differences, time delays, or boolean-based responses.

The attack can be executed remotely over the network without requiring any authentication or user interaction, and the vulnerability has a scope change impact, meaning it can affect resources beyond the vulnerable component itself. Successful exploitation primarily impacts confidentiality by enabling unauthorized access to sensitive database contents, with limited availability impact possible through resource-intensive queries.

Root Cause

The root cause of this vulnerability lies in the plugin's failure to properly sanitize or parameterize user-supplied input before incorporating it into SQL queries. WordPress plugins that directly concatenate user input into database queries without using prepared statements (via $wpdb->prepare()) are susceptible to SQL injection attacks.

The TicketBAI Facturas para WooCommerce plugin processes invoicing-related data that likely includes order IDs, customer identifiers, or date parameters. When these inputs are passed directly to SQL queries without proper escaping or validation, attackers can manipulate the query logic to extract unauthorized data.

Attack Vector

The attack vector for CVE-2025-24767 involves crafting malicious HTTP requests that inject SQL syntax into vulnerable parameters processed by the plugin. Since this is a blind SQL injection, attackers typically employ one of two techniques:

Boolean-Based Blind Injection: The attacker sends requests with SQL conditions that evaluate to true or false, observing differences in application responses to infer database contents character by character.

Time-Based Blind Injection: The attacker injects SQL commands that introduce deliberate delays (such as SLEEP() in MySQL), measuring response times to determine if injected conditions are true.

Because no authentication is required and the attack can be performed over the network, any WordPress site running the vulnerable plugin version is potentially at risk from internet-based attackers.

Detection Methods for CVE-2025-24767

Indicators of Compromise

• Unusual or malformed requests to WordPress endpoints associated with the wp-ticketbai plugin containing SQL syntax characters such as single quotes, UNION, SELECT, SLEEP(), or BENCHMARK()
• Database query logs showing unexpected or malformed SQL statements originating from plugin-related functions
• Abnormally slow response times for specific plugin endpoints indicating potential time-based injection attempts
• Web application firewall logs showing blocked SQL injection attempts targeting WooCommerce or invoicing-related URLs

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block common SQL injection patterns in HTTP requests
• Enable WordPress database query logging and monitor for anomalous or unauthorized queries
• Implement runtime application self-protection (RASP) solutions to detect SQL injection attempts at the application layer
• Review access logs for repeated requests to plugin endpoints with unusual parameter values or encoding

Monitoring Recommendations

• Configure alerting for SQL injection signatures in WAF and IDS/IPS systems
• Monitor database server performance for unexpected spikes in query execution time that may indicate time-based injection probing
• Set up file integrity monitoring on WordPress plugin directories to detect unauthorized modifications
• Enable audit logging for WordPress administrator actions and database access

How to Mitigate CVE-2025-24767

Immediate Actions Required

• Update the TicketBAI Facturas para WooCommerce plugin to a patched version immediately if available from the vendor
• If no patch is available, consider temporarily deactivating the wp-ticketbai plugin until a security update is released
• Implement WAF rules to block SQL injection attempts targeting the affected plugin endpoints
• Review database logs and access records for signs of prior exploitation

Patch Information

Security researchers at Patchstack have documented this vulnerability. Administrators should monitor the Patchstack WordPress Vulnerability Report for patch availability and update guidance from the plugin vendor.

Organizations running affected versions should prioritize updating to a version newer than 3.19 once released by facturaone.

Workarounds

• Temporarily disable the TicketBAI Facturas para WooCommerce plugin if it is not critical for business operations
• Restrict access to WordPress admin and plugin endpoints using IP allowlisting at the web server or firewall level
• Implement a virtual patching rule in your WAF to sanitize or block requests containing SQL injection patterns
• Consider using WordPress security plugins that provide real-time SQL injection protection

# Example: Restrict access to wp-admin and plugin endpoints in Apache .htaccess
<Files "wp-login.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>

# Block common SQL injection patterns (ModSecurity rule example)
SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt Detected'"
