CVE-2025-12984: Advanced Ads Plugin SQLi Vulnerability

CVE-2025-12984 Overview

The Advanced Ads – Ad Manager & AdSense plugin for WordPress contains a SQL Injection vulnerability in the order parameter affecting all versions up to and including 2.0.15. The vulnerability stems from insufficient escaping on the user-supplied parameter and a lack of sufficient preparation on the existing SQL query. This flaw allows authenticated attackers with Administrator-level access and above to append additional SQL queries into already existing queries, enabling extraction of sensitive information from the database.

Critical Impact

Authenticated attackers with administrator privileges can exploit this SQL Injection vulnerability to extract sensitive data from the WordPress database, potentially compromising user credentials, configuration data, and other confidential information.

Affected Products

• Advanced Ads – Ad Manager & AdSense plugin for WordPress versions up to and including 2.0.15
• WordPress installations running vulnerable versions of the Advanced Ads plugin
• Sites utilizing the placement list table functionality within the plugin's admin interface

Technical Details for CVE-2025-12984

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists within the Advanced Ads plugin's placement list table functionality, specifically in the class-placement-list-table.php file. The order parameter fails to properly sanitize user input before incorporating it into SQL queries. When an authenticated administrator submits a crafted request containing malicious SQL syntax through the order parameter, the application fails to validate or escape this input appropriately.

The lack of prepared statements or parameterized queries in this code path allows attackers to manipulate the SQL query structure. While the attack requires administrator-level authentication, compromised admin accounts or malicious insiders could leverage this vulnerability to extract sensitive database contents beyond their normal access scope.

Root Cause

The root cause of this vulnerability is the insufficient input validation and lack of proper SQL query preparation in the placement list table handling code. The order parameter is directly incorporated into SQL queries without adequate escaping or the use of parameterized queries, violating secure coding practices for database interactions in PHP and WordPress development.

Attack Vector

The attack is executed over the network and requires the attacker to have valid administrator credentials for the target WordPress installation. Once authenticated, the attacker can manipulate the order parameter in requests to the placement list table functionality. The crafted parameter value includes SQL syntax that modifies the query's behavior, allowing the attacker to extract data from the database through techniques such as UNION-based injection, boolean-based blind injection, or time-based blind injection.

The vulnerability is located in the plugin's admin interface, specifically within the file handling placement list table operations. An attacker would craft malicious input containing SQL statements designed to extract information from database tables, including potentially sensitive WordPress user data, plugin configurations, or other stored content.

Detection Methods for CVE-2025-12984

Indicators of Compromise

• Unusual or malformed requests to WordPress admin endpoints containing SQL syntax in the order parameter
• Database query logs showing unexpected SQL statements or UNION-based queries originating from the Advanced Ads plugin
• Administrative user accounts exhibiting abnormal behavior patterns or accessing the placement list table functionality with suspicious parameters
• Evidence of data exfiltration attempts through time-based delays or error-based responses in application logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in request parameters
• Enable verbose logging for WordPress admin actions and monitor for anomalous database queries
• Deploy endpoint detection solutions like SentinelOne to identify suspicious process behavior and network communications
• Regularly audit WordPress admin user accounts for unauthorized access or privilege escalation

Monitoring Recommendations

• Configure database query logging to capture and analyze queries originating from the Advanced Ads plugin
• Set up alerts for authentication events followed by unusual admin panel activity
• Monitor web server access logs for patterns indicative of SQL injection testing or exploitation attempts
• Implement file integrity monitoring on plugin files to detect unauthorized modifications

How to Mitigate CVE-2025-12984

Immediate Actions Required

• Update the Advanced Ads plugin to a version newer than 2.0.15 that contains the security patch
• Review WordPress admin user accounts and ensure only authorized personnel have administrator access
• Audit database access logs for any evidence of prior exploitation attempts
• Consider temporarily disabling the Advanced Ads plugin until the update can be applied if immediate patching is not possible

Patch Information

The vulnerability has been addressed in versions released after 2.0.15. Administrators should update to the latest available version of the Advanced Ads plugin through the WordPress plugin update mechanism. The patch details can be reviewed in the WordPress Plugin Change Log. Additional technical details about the vulnerability are available in the Wordfence Vulnerability Analysis.

Workarounds

• Restrict WordPress admin access to trusted IP addresses only using .htaccess or server-level firewall rules
• Implement additional authentication factors for administrator accounts to reduce the risk of credential compromise
• Deploy a WAF with SQL injection detection rules to filter malicious requests before they reach the application
• Regularly backup the WordPress database to enable recovery in case of successful data manipulation

# Example: Restrict wp-admin access by IP in .htaccess
# Add to .htaccess in wp-admin directory
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REMOTE_ADDR} !^192\.168\.1\.100$
RewriteCond %{REMOTE_ADDR} !^10\.0\.0\.50$
RewriteRule .* - [F,L]
</IfModule>
