CVE-2025-47573: mojoomla School Management SQLi Flaw

CVE-2025-47573 Overview

CVE-2025-47573 is a critical SQL Injection vulnerability affecting the mojoomla School Management plugin for WordPress. This vulnerability allows unauthenticated attackers to perform Blind SQL Injection attacks against vulnerable installations. Due to improper neutralization of special elements in SQL commands, attackers can manipulate database queries to extract sensitive information or compromise the underlying database.

Critical Impact

Unauthenticated attackers can exploit this Blind SQL Injection vulnerability to extract sensitive data from the WordPress database, including user credentials, student records, and other confidential school management data.

Affected Products

• mojoomla School Management plugin for WordPress versions through 92.0.0
• WordPress installations using the vulnerable School Management System plugin

Technical Details for CVE-2025-47573

Vulnerability Analysis

This vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The School Management plugin fails to properly sanitize user-supplied input before incorporating it into SQL queries executed against the WordPress database. This allows attackers to inject malicious SQL syntax that alters the intended query logic.

The Blind SQL Injection nature of this vulnerability means that while the application does not directly return database contents in error messages or responses, attackers can infer information through time-based or boolean-based inference techniques. By crafting specific payloads and observing application behavior differences, attackers can systematically extract sensitive data character by character.

The network-accessible attack vector with no authentication requirements makes this vulnerability particularly dangerous, as any internet-facing WordPress installation with the vulnerable plugin can be targeted without prior access or credentials.

Root Cause

The root cause is insufficient input validation and sanitization in the School Management plugin. User-controllable input is directly concatenated or interpolated into SQL queries without proper parameterization or escaping. WordPress provides prepared statements through the $wpdb->prepare() function specifically to prevent SQL injection, but the vulnerable code paths fail to utilize these secure coding practices.

Attack Vector

The vulnerability is exploitable over the network by unauthenticated remote attackers. Since no user interaction is required and no privileges are needed, an attacker can directly target the vulnerable endpoint. The attack involves sending specially crafted HTTP requests containing SQL injection payloads to the affected plugin functionality.

Typical Blind SQL Injection exploitation involves:

1. Identifying vulnerable parameters that interact with the database
2. Crafting boolean-based payloads to determine true/false conditions
3. Using time-based techniques (e.g., SLEEP() or BENCHMARK() functions) to confirm injection
4. Systematically extracting database contents through iterative queries

Detection Methods for CVE-2025-47573

Indicators of Compromise

• Unusual database query patterns in MySQL slow query logs or general logs
• Increased response times on specific plugin endpoints indicating time-based SQL injection attempts
• Web application firewall alerts for SQL injection patterns targeting the School Management plugin
• Unexpected database access or data exfiltration from wp_users or custom school management tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns including UNION SELECT, SLEEP(), BENCHMARK(), and boolean-based injection syntax
• Enable and monitor WordPress database query logging to identify suspicious query patterns
• Implement runtime application self-protection (RASP) solutions to detect SQL injection attempts at the application layer
• Configure SentinelOne Singularity to monitor for anomalous database access patterns and suspicious PHP process behavior

Monitoring Recommendations

• Enable verbose logging on the WordPress database server to capture all queries executed by the School Management plugin
• Monitor HTTP access logs for requests containing SQL metacharacters (single quotes, double dashes, semicolons) targeting plugin endpoints
• Set up alerts for unusual database connection patterns or query execution times that may indicate active exploitation

How to Mitigate CVE-2025-47573

Immediate Actions Required

• Audit your WordPress installation to determine if the School Management plugin by mojoomla is installed and identify the installed version
• If using a vulnerable version (through 92.0.0), consider temporarily disabling the plugin until a patched version is available
• Implement WAF rules to block SQL injection attempts targeting the affected plugin endpoints
• Review database access logs for signs of prior exploitation and assess potential data exposure

Patch Information

Monitor the official mojoomla School Management plugin page and the Patchstack Vulnerability Report for updates regarding security patches. Apply vendor-supplied patches immediately when they become available.

Workarounds

• Implement a Web Application Firewall with SQL injection detection rules as a compensating control
• Restrict network access to WordPress admin and plugin endpoints using IP allowlisting where possible
• Consider using WordPress security plugins that provide real-time protection against SQL injection attacks
• Temporarily disable the School Management plugin if it is not critical to operations until a patch is released

# Example: Disable the plugin via WP-CLI until patched
wp plugin deactivate school-management

# Verify plugin status
wp plugin list --name=school-management --format=table
