CVE-2025-22290: LTL Freight Quotes SQL Injection Flaw

CVE-2025-22290 Overview

CVE-2025-22290 is a SQL Injection vulnerability affecting the LTL Freight Quotes – FreightQuote Edition WordPress plugin developed by enituretechnology. This vulnerability allows attackers to manipulate SQL queries through improper neutralization of special elements, potentially leading to unauthorized database access, data exfiltration, and compromise of the underlying WordPress installation.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability remotely to extract sensitive data from WordPress databases, potentially compromising user credentials, customer information, and other confidential data stored by e-commerce sites using this freight quoting plugin.

Affected Products

• LTL Freight Quotes – FreightQuote Edition versions up to and including 2.3.11
• WordPress installations running the vulnerable plugin versions
• E-commerce sites utilizing FreightQuote shipping integration

Technical Details for CVE-2025-22290

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists in the LTL Freight Quotes – FreightQuote Edition WordPress plugin through version 2.3.11. The vulnerability stems from improper sanitization of user-supplied input before it is incorporated into SQL queries. When exploited, an attacker can inject malicious SQL statements that execute in the context of the database user, potentially allowing full database access.

The network-based attack vector with no authentication requirements makes this vulnerability particularly dangerous for publicly accessible WordPress e-commerce installations. The scope is changed, meaning a successful exploit can affect resources beyond the vulnerable component itself, potentially impacting the entire WordPress database and associated systems.

Root Cause

The root cause of this vulnerability is the failure to properly neutralize special elements used in SQL commands. The plugin does not adequately sanitize, escape, or parameterize user input before constructing SQL queries. This allows specially crafted input containing SQL metacharacters to modify the intended query structure and execute arbitrary SQL commands.

WordPress provides functions like $wpdb->prepare() for parameterized queries that prevent SQL injection, but the vulnerable code paths in this plugin fail to utilize these protective mechanisms consistently.

Attack Vector

The attack can be conducted remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable input parameters in the plugin. These payloads are then processed by the application and executed against the database.

Successful exploitation could enable attackers to:

• Extract sensitive data including usernames, passwords, and customer information
• Modify or delete database records
• Potentially escalate to remote code execution through database features like INTO OUTFILE or user-defined functions

The vulnerability can be exploited by sending specially crafted requests to endpoints handled by the LTL Freight Quotes plugin, where user-controllable input is concatenated directly into SQL queries. Attackers typically use techniques such as UNION-based injection, boolean-based blind injection, or time-based blind injection to extract database contents. For detailed technical information, refer to the Patchstack SQL Injection Advisory.

Detection Methods for CVE-2025-22290

Indicators of Compromise

• Unusual database query patterns or errors in WordPress/web server logs
• Requests containing SQL injection patterns (e.g., UNION SELECT, OR 1=1, '--) in freight quote related parameters
• Unexpected data access patterns or bulk data extraction from WordPress databases
• Modified database records or new administrator accounts

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the LTL Freight Quotes plugin
• Monitor application logs for SQL syntax errors that may indicate injection attempts
• Deploy database activity monitoring to detect unusual query patterns or unauthorized data access
• Use SentinelOne Singularity to detect post-exploitation activities and suspicious process behavior

Monitoring Recommendations

• Enable verbose logging on WordPress and the web server to capture request parameters
• Configure alerting for database errors and unusual query execution times that may indicate time-based blind SQL injection
• Monitor for outbound data transfers that could indicate successful data exfiltration
• Implement integrity monitoring on WordPress database tables to detect unauthorized modifications

How to Mitigate CVE-2025-22290

Immediate Actions Required

• Update the LTL Freight Quotes – FreightQuote Edition plugin to a patched version if available
• If no patch is available, consider temporarily disabling the plugin until a fix is released
• Implement WAF rules to block SQL injection attempts targeting the plugin
• Review database access logs for signs of prior exploitation
• Audit and rotate database credentials if compromise is suspected

Patch Information

Organizations should check the WordPress plugin repository and the vendor's website for security updates addressing this vulnerability. The vulnerability affects all versions through 2.3.11, so any version at or below this should be considered vulnerable. Consult the Patchstack SQL Injection Advisory for the latest remediation guidance.

Workarounds

• Deploy a Web Application Firewall with SQL injection detection rules as a compensating control
• Restrict access to the WordPress admin panel and plugin endpoints to trusted IP addresses
• Implement database user least privilege principles to limit the impact of successful SQL injection
• Consider using WordPress security plugins that provide virtual patching capabilities
