Vulnerability Assessment

Weakness	CWE CWE-89 OWASP Top 10:2025 A05:2025 - Injection ASVS 5.0 V1 - Encoding and Sanitization Parameterized queries, prepared statements MITRE ATT&CK 2 techniques across 2 tactics: Initial Access, Persistence The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. Sign in to read
Exploitation Conditions	No special conditions - remote unauthenticated exploitation against default configurations of Online Art Gallery Shop 1.0. The vulnerable endpoint /admin/adminHome.php must be accessible from the attacker's network position. Note that while the path suggests an admin interface, the CVSS vector confirms no authentication is required (PR:N), indicating either a misconfiguration or design flaw in access controls.
Impact	The vulnerability presents high real-world risk based on multiple factors. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) confirms remote unauthenticated exploitation with low complexity and no user interaction required. The EPSS data is not provided, but the existence of publicly available exploit code significantly increases the likelihood of exploitation. The CVSS environmental metrics show E:P (proof-of-concept exists) and RC:R (reasonable confidence), aligning with the published exploit on GitHub. This is not listed in CISA KEV, suggesting it may not be actively exploited at scale yet, but the low barrier to exploitation makes it a priority for systems running this software.
Exploit ScenarioDerived	An attacker sends a crafted HTTP request to /admin/adminHome.php with malicious SQL code in the social_linked parameter. The injected SQL executes in the database context, potentially allowing data extraction, modification, or deletion. Given the admin panel context, this could lead to full application compromise.

This Month Plan within 30 days. Why: MEDIUM severity (CVSS 4.0-6.9).

AnalysisAIv1 – May 24, 2026

SQL injection in Online Art Gallery Shop 1.0 allows unauthenticated remote attackers to manipulate database queries through the social_linked parameter in /admin/adminHome.php. The vulnerability has publicly available exploit code and a CVSS score of 7.3, indicating high severity with the ability to impact confidentiality, integrity, and availability of the application.

RemediationAI

No vendor-released patch identified at time of analysis. As an immediate mitigation, restrict access to /admin/adminHome.php through web server access controls or authentication mechanisms, though this may break legitimate admin functionality. Implement input validation and parameterized queries for the social_linked parameter if source code access is available. Consider deploying a Web Application Firewall (WAF) with SQL injection rules as a temporary measure, though determined attackers may bypass generic rules. Monitor database logs for suspicious queries targeting the admin panel.

Technical ContextAI · show details

Online Art Gallery Shop is a PHP-based web application by projectworlds. The vulnerability stems from improper input validation in the admin panel file /admin/adminHome.php, specifically when processing the social_linked parameter. This is a classic SQL injection vulnerability (CWE-89) where user-supplied input is incorporated into SQL queries without proper sanitization or parameterization, allowing attackers to inject arbitrary SQL commands.
