CVE-2025-15169 identifies a SQL injection vulnerability in BiggiDroid Simple PHP CMS version 1.0, specifically within the /admin/editsite.php script. The vulnerability stems from insufficient input validation and sanitization of the 'ID' parameter, which is used in SQL queries without proper escaping or parameterization. This allows an attacker with authenticated access (high privileges) to remotely inject malicious SQL code by manipulating the 'ID' argument, potentially leading to unauthorized data access, modification, or deletion. The vulnerability does not require user interaction but does require authentication, limiting exposure somewhat but still posing a significant risk to administrators. The vendor was notified but has not responded or issued a patch, and public exploit code is available, increasing the likelihood of exploitation. The CVSS 4.0 score is 5.1 (medium severity), reflecting the moderate impact on confidentiality, integrity, and availability, and the requirement for authenticated access. The vulnerability affects only version 1.0 of the Simple PHP CMS, which is a lightweight content management system likely used by smaller organizations or niche deployments. No known exploits in the wild have been reported yet, but the public availability of exploit code means attackers could develop targeted attacks quickly.

For European organizations, this vulnerability poses a moderate risk primarily to those using BiggiDroid Simple PHP CMS 1.0, particularly if the administrative interface is accessible remotely. Successful exploitation could lead to unauthorized access to sensitive data, data tampering, or disruption of CMS functionality, impacting confidentiality, integrity, and availability. Organizations relying on this CMS for website or intranet management could face data breaches or defacement. Given the requirement for authenticated access, the risk is higher if credential management is weak or if administrative interfaces are exposed without adequate network controls. The lack of vendor response and patch availability increases the window of exposure. This could be particularly impactful for small and medium enterprises (SMEs) in Europe that may lack dedicated security teams or patch management processes. Additionally, regulatory requirements such as GDPR impose strict data protection obligations, so exploitation leading to data breaches could result in legal and financial penalties.

1. Immediately restrict access to the /admin/editsite.php interface using network-level controls such as VPNs, IP whitelisting, or firewall rules to limit exposure to trusted administrators only. 2. Conduct a thorough code audit of the CMS, focusing on input validation and SQL query construction, and implement parameterized queries or prepared statements to prevent SQL injection. 3. If possible, upgrade to a newer, patched version of the CMS or migrate to a more secure platform if no vendor support is forthcoming. 4. Implement strong authentication mechanisms, including multi-factor authentication, to reduce the risk of compromised credentials. 5. Monitor logs for suspicious activity related to the 'ID' parameter or unusual database queries. 6. Educate administrators on secure password practices and restrict administrative privileges to the minimum necessary. 7. Consider deploying Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the vulnerable parameter. 8. Regularly back up CMS data and configurations to enable rapid recovery in case of compromise.
