CVE-2025-24773: WPCRM WordPress Plugin SQLi Vulnerability

CVE-2025-24773 Overview

CVE-2025-24773 is a critical SQL Injection vulnerability affecting the WPCRM - CRM for Contact form CF7 & WooCommerce plugin for WordPress. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing attackers to inject malicious SQL queries through the plugin's input handling mechanisms.

This vulnerability enables unauthenticated attackers to manipulate database queries, potentially leading to unauthorized data extraction, modification, or deletion of sensitive customer relationship management data stored within WordPress installations using this plugin.

Critical Impact

Unauthenticated SQL Injection vulnerability allows attackers to extract sensitive CRM data, including customer contact information from Contact Form 7 submissions and WooCommerce transaction records, without any authentication requirements.

Affected Products

• WPCRM - CRM for Contact form CF7 & WooCommerce versions up to and including 3.2.0
• WordPress installations using the affected WPCRM plugin
• Sites integrating WPCRM with Contact Form 7 (CF7) and WooCommerce

Technical Details for CVE-2025-24773

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists within the WPCRM plugin's data processing functionality. The plugin fails to properly sanitize user-supplied input before incorporating it into SQL queries, creating a direct path for attackers to inject arbitrary SQL commands.

The network-accessible nature of this vulnerability means attackers can exploit it remotely without requiring any prior authentication or user interaction. The scope is changed, indicating that the vulnerability's impact extends beyond the vulnerable component itself—potentially compromising the entire WordPress database and any connected systems sharing the same database server.

The primary impact is on data confidentiality, with the potential for complete disclosure of all database contents. Additionally, a limited availability impact exists where attackers could disrupt database operations through malicious queries.

Root Cause

The root cause of CVE-2025-24773 is the failure to implement proper input validation and parameterized queries within the WPCRM plugin. User-controllable input is directly concatenated into SQL query strings without adequate sanitization or use of prepared statements.

WordPress provides built-in functions like $wpdb->prepare() for safe database interactions, but the vulnerable code paths in WPCRM bypass these protections, allowing special SQL characters and commands to be interpreted as part of the query structure rather than as literal data values.

Attack Vector

The attack vector is network-based, allowing remote exploitation by unauthenticated attackers. The exploitation requires no user interaction and has low attack complexity, making it highly accessible to threat actors.

Attackers can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable plugin endpoints. These payloads can leverage techniques such as UNION-based injection for data extraction, time-based blind injection for database enumeration, or error-based injection depending on the server configuration.

The vulnerability can be exploited to extract sensitive CRM data including customer names, email addresses, phone numbers, purchase histories from WooCommerce integration, and any custom fields stored by the Contact Form 7 integration. In severe cases, attackers may escalate to reading WordPress user credentials or gaining administrative access.

Detection Methods for CVE-2025-24773

Indicators of Compromise

• Unusual database query patterns in MySQL/MariaDB slow query logs indicating injection attempts
• HTTP access logs containing SQL syntax characters (', ", ;, --, UNION, SELECT) in request parameters targeting WPCRM endpoints
• Unexpected data extraction or modification in CRM-related database tables
• Error messages in PHP logs indicating SQL syntax errors from malformed injection attempts

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to WordPress installations
• Implement real-time monitoring of database queries for anomalous patterns such as UNION SELECT, SLEEP(), or BENCHMARK() functions
• Configure intrusion detection systems to alert on high-frequency requests to WPCRM plugin endpoints
• Review WordPress audit logs for unusual data access patterns or bulk data retrieval

Monitoring Recommendations

• Enable detailed logging for all database queries on WordPress sites using WPCRM
• Set up alerts for failed authentication attempts following database enumeration patterns
• Monitor outbound network traffic for potential data exfiltration following exploitation
• Regularly audit CRM data integrity to detect unauthorized modifications

How to Mitigate CVE-2025-24773

Immediate Actions Required

• Update WPCRM plugin to a patched version when available from the developer
• If no patch is available, consider temporarily deactivating the WPCRM plugin until a fix is released
• Review database access logs for signs of prior exploitation
• Implement WAF rules to filter SQL injection attempts targeting the plugin
• Consider restricting access to WordPress admin and plugin endpoints at the network level

Patch Information

Users should monitor the Patchstack WPCRM SQL Injection Advisory for updates regarding official patches from the plugin developer. As the vulnerability affects versions through 3.2.0, users should update to any version newer than 3.2.0 once released.

Until an official patch is available, implementing virtual patching through a WAF or security plugin is strongly recommended.

Workarounds

• Deploy a Web Application Firewall with SQL injection detection rules as a virtual patch
• Use WordPress security plugins that offer real-time protection against SQL injection attacks
• Restrict database user privileges for the WordPress installation to minimum required permissions
• Implement database activity monitoring to detect and alert on suspicious query patterns
• Consider using alternative CRM solutions until the vulnerability is officially patched

# Example WAF rule for ModSecurity to block common SQL injection patterns
# Add to WordPress .htaccess or server configuration
SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt Detected'"

# Restrict database permissions (MySQL example)
# REVOKE FILE, SUPER, PROCESS ON *.* FROM 'wordpress_user'@'localhost';
