CVE-2025-39395: WPAMS SQL Injection Vulnerability

CVE-2025-39395 Overview

CVE-2025-39395 is a critical SQL Injection vulnerability affecting the WPAMS (WordPress Apartment Management System) plugin developed by mojoomla. This vulnerability allows unauthenticated attackers to inject malicious SQL commands through improperly sanitized user input, potentially leading to unauthorized database access, data exfiltration, and compromise of sensitive information stored within WordPress installations.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability to extract sensitive data from WordPress databases, including user credentials, personal information, and other confidential records without any prior authentication.

Affected Products

• WPAMS (WordPress Apartment Management System) plugin versions through 44.0 (17-08-2023)
• WordPress installations utilizing the vulnerable WPAMS plugin
• All websites running the apartment-management WordPress plugin up to and including the affected version

Technical Details for CVE-2025-39395

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists in the WPAMS WordPress plugin due to improper neutralization of special elements used in SQL commands. The vulnerability allows attackers to manipulate database queries by injecting malicious SQL code through user-controllable input parameters.

The flaw enables unauthenticated remote attackers to interact directly with the underlying database without proper authorization. This can result in unauthorized data extraction, database modification, or in severe cases, complete database compromise. The vulnerability has a changed scope, meaning successful exploitation could impact resources beyond the vulnerable component itself, potentially affecting the entire WordPress installation and associated systems.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize and validate user-supplied input before incorporating it into SQL queries. The WPAMS plugin does not adequately implement prepared statements or parameterized queries, allowing specially crafted input to be interpreted as SQL commands rather than data.

WordPress plugins are expected to use the $wpdb->prepare() function or similar mechanisms to safely handle user input in database operations. The absence of such protective measures in the vulnerable code paths enables attackers to inject arbitrary SQL syntax that gets executed by the database engine.

Attack Vector

The attack can be executed remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable parameters in the WPAMS plugin.

The vulnerability is exploited by submitting specially crafted input that breaks out of the intended SQL query structure and executes attacker-controlled commands. Common techniques include UNION-based injection to extract data from other tables, boolean-based blind injection to infer database contents, and time-based blind injection for scenarios where direct output is not visible.

Detection Methods for CVE-2025-39395

Indicators of Compromise

• Unusual or malformed HTTP requests to WPAMS plugin endpoints containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
• Database error messages appearing in HTTP responses or server logs indicating SQL syntax errors
• Unexpected database queries logged with anomalous patterns or excessive data retrieval operations
• Evidence of data exfiltration through abnormal outbound traffic or database dumps

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in requests targeting WordPress plugin endpoints
• Enable WordPress database query logging and monitor for suspicious query patterns containing injection signatures
• Implement Intrusion Detection System (IDS) signatures for SQL injection attempts targeting the /wp-content/plugins/apartment-management/ path
• Configure real-time alerting for database errors that may indicate exploitation attempts

Monitoring Recommendations

• Monitor HTTP access logs for requests containing encoded SQL characters (%27, %22, %2D%2D) targeting WPAMS plugin files
• Track database user activity for unusual query patterns or unauthorized data access attempts
• Review authentication logs for successful logins following potential SQL injection exploitation
• Audit database schema changes that may indicate post-exploitation persistence mechanisms

How to Mitigate CVE-2025-39395

Immediate Actions Required

• Immediately disable or deactivate the WPAMS plugin if it is not critical to site operations
• Review database audit logs to determine if exploitation has already occurred
• Implement WAF rules to block SQL injection patterns targeting the vulnerable plugin endpoints
• Restrict database user privileges to limit potential damage from successful exploitation
• Consider temporarily restricting public access to the affected WordPress site until remediation is complete

Patch Information

Organizations should check with the plugin vendor mojoomla for an updated version of WPAMS that addresses this SQL Injection vulnerability. Monitor the Patchstack advisory for updates on available patches. If no patch is available, consider removing the plugin entirely and seeking alternative solutions for apartment management functionality.

Workarounds

• Implement a Web Application Firewall with SQL injection protection rules to filter malicious requests before they reach the application
• Use WordPress security plugins that provide virtual patching capabilities to protect against known vulnerabilities
• Apply network-level access controls to restrict access to WordPress admin areas and plugin endpoints from trusted IP addresses only
• Disable the plugin entirely until a security update is released by the vendor

# Configuration example - Disable WPAMS plugin via WP-CLI
wp plugin deactivate apartment-management --path=/var/www/html/wordpress

# Verify plugin is deactivated
wp plugin list --status=inactive --path=/var/www/html/wordpress | grep apartment-management
