CVE-2025-48283: Majestic Support SQL Injection Flaw

CVE-2025-48283 Overview

CVE-2025-48283 is a critical SQL Injection vulnerability discovered in the Majestic Support WordPress plugin. This vulnerability allows unauthenticated attackers to inject malicious SQL commands through improperly sanitized user input, potentially leading to unauthorized access to sensitive database information and limited system availability impact.

Critical Impact
Unauthenticated SQL Injection vulnerability enabling attackers to extract sensitive data from WordPress databases without any user interaction or authentication requirements.

Affected Products

Majestic Support WordPress Plugin versions through 1.1.0

Technical Details for CVE-2025-48283

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) in Majestic Support arises from improper neutralization of special elements used in SQL commands. The vulnerability allows attackers to manipulate database queries by injecting malicious SQL statements through user-controllable input fields.

The attack can be executed remotely over the network without requiring any authentication or user interaction, and the scope is changed, meaning the vulnerable component impacts resources beyond its security scope. The primary impact is confidentiality breach with high severity, allowing attackers to potentially extract sensitive information from the WordPress database including user credentials, configuration data, and other stored content. There is also a limited availability impact.

Root Cause

The root cause of this vulnerability is insufficient input validation and improper sanitization of user-supplied data before it is incorporated into SQL queries. The Majestic Support plugin fails to properly escape or parameterize user input, allowing special SQL characters and commands to be interpreted as part of the database query rather than as literal data. This is a classic example of CWE-89: Improper Neutralization of Special Elements used in an SQL Command.

Attack Vector

The attack vector is network-based, allowing remote exploitation. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable parameters within the Majestic Support plugin. Since no authentication is required (PR:N) and no user interaction is needed (UI:N), the attack can be fully automated. The changed scope (S:C) indicates that successful exploitation can affect resources beyond the vulnerable plugin itself, potentially compromising the entire WordPress database.

The vulnerability allows attackers to perform various SQL injection techniques including:

Union-based injection to extract data from other database tables
Boolean-based blind injection to enumerate database contents
Time-based blind injection to confirm vulnerability presence
Error-based injection to reveal database structure information

Detection Methods for CVE-2025-48283

Indicators of Compromise

Unusual database queries in web server logs containing SQL syntax such as UNION SELECT, OR 1=1, --, or encoded variants
Unexpected database errors or exceptions in WordPress error logs
Abnormal traffic patterns to Majestic Support plugin endpoints
Evidence of data exfiltration or unauthorized database access attempts

Detection Strategies

Monitor web application firewall (WAF) logs for SQL injection patterns targeting the Majestic Support plugin
Implement database activity monitoring to detect anomalous query patterns or unauthorized data access
Review access logs for requests containing SQL metacharacters (', ", ;, --, /**/)
Deploy intrusion detection systems (IDS) with SQL injection signature rules

Monitoring Recommendations

Enable detailed logging for WordPress and database queries to capture potential exploitation attempts
Configure real-time alerting for SQL injection patterns in web traffic
Regularly audit plugin activity and database access logs for suspicious behavior
Implement behavioral analysis to detect unusual database query patterns

How to Mitigate CVE-2025-48283

Immediate Actions Required

Immediately disable or uninstall the Majestic Support plugin if running version 1.1.0 or earlier
Review database logs for evidence of exploitation and potential data breach
Implement Web Application Firewall (WAF) rules to block SQL injection attempts targeting the plugin
If compromise is suspected, rotate all database credentials and WordPress secret keys

Patch Information

Check for updated versions of the Majestic Support plugin that address this SQL injection vulnerability. Monitor the Patchstack vulnerability database for patch availability and updated version information. Until a patch is available, the plugin should be disabled on production systems.

Workarounds

Disable the Majestic Support plugin entirely until a security patch is released
Implement strict WAF rules to filter SQL injection payloads targeting known vulnerable endpoints
Restrict access to the WordPress admin and plugin functionality to trusted IP addresses only
Consider alternative support ticket plugins with better security track records
