CVE-2026-3758: Online Art Gallery Shop SQLi Vulnerability

CVE-2026-3758 Overview

A SQL Injection vulnerability has been identified in Projectworlds Online Art Gallery Shop version 1.0. The vulnerability exists in the /admin/adminHome.php file, where manipulation of the Info argument allows attackers to inject malicious SQL queries. This flaw enables remote exploitation without authentication, potentially allowing attackers to extract, modify, or delete sensitive data from the application's database.

Critical Impact

This SQL Injection vulnerability allows remote attackers to manipulate database queries through the Info parameter, potentially leading to unauthorized data access, data manipulation, or complete database compromise.

Technical Details for CVE-2026-3758

Vulnerability Analysis

This SQL Injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) occurs due to insufficient input validation in the administrative interface of the Online Art Gallery Shop application. The vulnerable endpoint /admin/adminHome.php accepts user-supplied input through the Info parameter without proper sanitization or parameterization, allowing attackers to inject arbitrary SQL commands.

The vulnerability is network-accessible and requires no authentication or user interaction to exploit, making it particularly dangerous for exposed installations. Successful exploitation could allow an attacker to read sensitive data from the database, modify or delete records, or potentially escalate privileges depending on database configuration and permissions.

Root Cause

The root cause of this vulnerability is the direct incorporation of user-supplied input into SQL queries without proper sanitization or the use of prepared statements. The Info parameter value is concatenated directly into database queries executed by /admin/adminHome.php, allowing attackers to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack can be executed remotely over the network. An attacker sends a specially crafted HTTP request to the /admin/adminHome.php endpoint with malicious SQL code embedded in the Info parameter. The server-side PHP code processes this input without adequate validation, resulting in the injected SQL being executed against the backend database.

The exploitation methodology involves crafting payloads that manipulate the query structure—such as using single quotes to escape string contexts, UNION statements to extract additional data, or stacked queries to execute multiple commands. For detailed technical analysis and proof of concept information, refer to the GitHub Issue Discussion and VulDB entry #349736.

Detection Methods for CVE-2026-3758

Indicators of Compromise

• Unusual or malformed HTTP requests to /admin/adminHome.php containing SQL syntax in the Info parameter
• Database query logs showing unexpected SQL commands, UNION statements, or error-based injection patterns
• Abnormal database access patterns or queries accessing tables outside normal application behavior
• Web server logs containing URL-encoded SQL injection payloads targeting the admin interface

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in requests to /admin/adminHome.php
• Implement database activity monitoring to alert on suspicious query patterns or unauthorized data access
• Configure intrusion detection systems (IDS) with signatures for SQL injection attack patterns
• Enable verbose logging on the web application to capture all input parameters for forensic analysis

Monitoring Recommendations

• Monitor HTTP access logs for requests to /admin/adminHome.php with suspicious parameter values
• Set up alerts for database errors that may indicate failed injection attempts
• Track user account activity and database modifications for signs of unauthorized access
• Review authentication logs for the admin interface for anomalous login patterns

How to Mitigate CVE-2026-3758

Immediate Actions Required

• Restrict network access to the /admin/adminHome.php endpoint using firewall rules or access control lists
• Implement IP whitelisting for administrative interfaces to limit exposure
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Consider temporarily disabling the affected functionality until a patch is available

Patch Information

At the time of this publication, no official patch has been released by the vendor. Organizations using Projectworlds Online Art Gallery Shop 1.0 should monitor the vendor's communications and apply security updates as soon as they become available. Additional information can be found in the VulDB vulnerability submission.

Workarounds

• Implement input validation and sanitization for all user-supplied parameters, particularly the Info argument
• Use prepared statements or parameterized queries in all database interactions to prevent SQL injection
• Place the admin interface behind VPN access or require additional authentication factors
• Consider implementing a reverse proxy with SQL injection filtering capabilities
