CVE-2025-69304: Allmart Core Blind SQLi Vulnerability

CVE-2025-69304 Overview

CVE-2025-69304 is a critical Blind SQL Injection vulnerability affecting the Allmart WordPress plugin developed by TeconceTheme. The vulnerability exists in the allmart-core component and allows unauthenticated attackers to execute arbitrary SQL queries against the WordPress database through specially crafted input that bypasses input sanitization mechanisms.

Critical Impact

This vulnerability enables attackers to extract sensitive information from the WordPress database without authentication, potentially exposing user credentials, personal data, and other confidential information stored in the database.

Affected Products

• WordPress Allmart plugin (allmart-core) version 1.1 and earlier
• All WordPress installations using vulnerable versions of the Allmart theme plugin

Technical Details for CVE-2025-69304

Vulnerability Analysis

This vulnerability is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The Allmart plugin fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows attackers to inject malicious SQL code that the database server will execute alongside legitimate queries.

The Blind SQL Injection nature of this vulnerability means that while attackers cannot directly see query results in the application response, they can infer information through timing-based or boolean-based techniques. By crafting queries that cause measurable differences in server response times or behavior, attackers can systematically extract database contents character by character.

The network-accessible attack vector combined with no authentication requirements makes this vulnerability particularly dangerous, as any remote attacker can exploit it without needing valid credentials or user interaction.

Root Cause

The root cause of this vulnerability is insufficient input validation and improper use of database query construction in the allmart-core plugin. Instead of using parameterized queries or prepared statements with proper placeholder binding, the plugin directly concatenates user input into SQL query strings. This allows special SQL characters and commands to escape the intended data context and be interpreted as executable SQL code.

Attack Vector

The vulnerability is exploitable over the network by unauthenticated attackers. An attacker can send specially crafted HTTP requests containing SQL injection payloads to vulnerable endpoints in the Allmart plugin. Since this is a Blind SQL Injection, the attacker uses inference techniques to extract data:

1. Boolean-based Blind SQLi: Attacker sends queries that return different responses based on true/false conditions, allowing them to ask yes/no questions about the database contents
2. Time-based Blind SQLi: Attacker injects queries that cause deliberate delays when conditions are true, using response timing to infer database information

The exploitation does not require any privileges or user interaction, making it highly exploitable in automated attack scenarios.

Detection Methods for CVE-2025-69304

Indicators of Compromise

• Unusual or malformed HTTP requests containing SQL keywords (SELECT, UNION, SLEEP, BENCHMARK) in parameters targeting Allmart plugin endpoints
• Database logs showing execution of unexpected queries, particularly those with time delay functions
• Increased database query execution times without corresponding legitimate traffic increases
• Error logs containing SQL syntax errors from malformed injection attempts

Detection Strategies

• Deploy Web Application Firewall (WAF) rules specifically targeting SQL injection patterns in requests to WordPress plugin endpoints
• Enable detailed WordPress and database query logging to capture suspicious query patterns
• Implement anomaly detection for unusual patterns in HTTP request parameters
• Monitor for automated scanning tools commonly used to identify SQL injection vulnerabilities

Monitoring Recommendations

• Configure real-time alerting for SQL injection attack signatures in web server access logs
• Monitor database performance metrics for unusual spikes in query execution time that may indicate time-based SQLi exploitation
• Implement file integrity monitoring on the allmart-core plugin directory to detect unauthorized modifications
• Review WordPress database user privilege levels to ensure principle of least privilege

How to Mitigate CVE-2025-69304

Immediate Actions Required

• Update the Allmart plugin to a patched version when available from TeconceTheme
• If no patch is available, consider temporarily disabling the allmart-core plugin until a fix is released
• Implement WAF rules to block common SQL injection patterns targeting the affected plugin
• Review and restrict database user permissions to minimize potential damage from successful exploitation
• Audit database access logs for signs of prior exploitation

Patch Information

Users should monitor the Patchstack WordPress Vulnerability Advisory for updates on patch availability. Contact TeconceTheme for information on remediation timelines for Allmart versions 1.1 and earlier.

Workarounds

• Deploy a Web Application Firewall with SQL injection protection rules enabled
• Implement input validation at the server level using plugins like Wordfence or Sucuri that can filter malicious SQL patterns
• Restrict access to WordPress admin and plugin endpoints using IP allowlisting where feasible
• Consider using a virtual patching solution through your WAF to block exploitation attempts while awaiting an official patch

# Example: Block suspicious SQL injection patterns in Apache/nginx
# Add to .htaccess or nginx configuration

# Apache .htaccess example
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|drop|delete|update|concat|benchmark|sleep) [NC]
RewriteRule .* - [F,L]
