CVE-2025-8811 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Simple Art Gallery application, specifically within the /Admin/registration.php file. The vulnerability arises from improper sanitization or validation of the 'fname' parameter, which is used in SQL queries without adequate protection against injection attacks. An attacker can remotely exploit this flaw by manipulating the 'fname' argument to inject malicious SQL code, potentially allowing unauthorized access to the underlying database. This could lead to unauthorized data disclosure, data modification, or even complete compromise of the database server depending on the database permissions and configuration. The vulnerability does not require authentication or user interaction, making it easier to exploit remotely. The CVSS 4.0 score is 6.9, indicating a medium severity level, with the vector showing network attack vector, low attack complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the public disclosure of the vulnerability increases the risk of exploitation by threat actors.

For European organizations using Simple Art Gallery 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their data. An attacker exploiting this SQL injection could access sensitive user information, modify or delete records, or escalate their attack to gain further control over the affected systems. This is particularly concerning for organizations managing personal data subject to GDPR regulations, as data breaches could lead to regulatory penalties and reputational damage. Furthermore, if the database is integral to business operations, availability could also be impacted through destructive queries or denial-of-service conditions. The remote and unauthenticated nature of the exploit increases the attack surface, especially for organizations exposing the affected application to the internet without adequate network segmentation or web application firewalls.

Organizations should immediately assess their use of Simple Art Gallery version 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, applying virtual patches via web application firewalls (WAFs) that detect and block suspicious SQL injection patterns targeting the 'fname' parameter is recommended. Additionally, input validation and parameterized queries should be implemented to sanitize user inputs rigorously. Restricting database user permissions to the minimum necessary can limit the impact of a successful injection. Network-level controls such as limiting access to the /Admin/registration.php endpoint to trusted IPs and monitoring logs for unusual query patterns or repeated failed attempts can help detect and prevent exploitation. Regular security assessments and penetration testing should be conducted to identify similar injection points. Finally, organizations should prepare incident response plans to quickly contain and remediate any exploitation attempts.
