CVE-2025-8811 is a critical SQL Injection vulnerability identified in version 1.0 of the Simple Art Gallery application developed by code-projects. The vulnerability resides in the /Admin/registration.php file, specifically in the handling of the 'fname' parameter. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. The vulnerability does not require any authentication or user interaction, making it remotely exploitable over the network. The CVSS 4.0 base score is 6.9, indicating a medium severity level, with attack vector being network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is low to limited (VC:L, VI:L, VA:L), suggesting that while exploitation is possible, the extent of damage may be constrained by the application's design or database permissions. The vulnerability has been publicly disclosed but no known exploits are currently observed in the wild. The lack of available patches or mitigations from the vendor increases the urgency for organizations to implement defensive measures. The SQL Injection vulnerability could allow attackers to extract sensitive data, modify or delete records, or potentially escalate privileges depending on the database configuration. Given the nature of the application (an art gallery management system), the data at risk may include user registration details and administrative information, which could be leveraged for further attacks or data breaches.

For European organizations using Simple Art Gallery 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their data. Exploitation could lead to unauthorized disclosure of personal data, potentially violating GDPR requirements and resulting in legal and financial repercussions. The ability to remotely exploit the vulnerability without authentication increases the risk of automated attacks and widespread compromise. Organizations relying on this software for managing user registrations or administrative functions could face service disruptions or data manipulation, impacting business operations and reputation. Additionally, compromised systems could serve as pivot points for further attacks within the network. The medium severity rating suggests that while the vulnerability is serious, the actual impact may vary depending on the deployment environment and database security controls in place.

Since no official patches are currently available, European organizations should immediately implement input validation and parameterized queries or prepared statements in the /Admin/registration.php script to prevent SQL Injection. Employing Web Application Firewalls (WAFs) with specific rules to detect and block SQL Injection attempts targeting the 'fname' parameter can provide an interim defense. Organizations should conduct thorough code reviews and security testing of the affected module to identify and remediate injection points. Restricting database user privileges to the minimum necessary can limit the potential damage from exploitation. Monitoring web server and database logs for unusual query patterns or failed injection attempts can help detect exploitation attempts early. If feasible, isolating the affected application or restricting access to the administration interface via network segmentation or VPN can reduce exposure. Finally, organizations should plan to upgrade or replace the vulnerable software once a vendor patch or secure version becomes available.
