CVE-2025-15169 is a SQL injection vulnerability identified in BiggiDroid Simple PHP CMS version 1.0, located in the /admin/editsite.php script. The issue stems from insufficient input validation or sanitization of the 'ID' parameter, which is used in SQL queries without proper escaping or parameterization. This flaw allows an authenticated attacker with high privileges to inject malicious SQL code remotely, potentially manipulating the backend database. The vulnerability does not require user interaction but does require the attacker to be authenticated with elevated privileges, which limits the attack surface but still poses a significant risk. The vendor was notified early but has not issued any patches or responses, and public exploit code has been released, increasing the likelihood of exploitation attempts. The CVSS v4.0 base score is 5.1 (medium severity), reflecting the moderate impact and exploitation complexity. The vulnerability can lead to unauthorized data disclosure, data modification, or denial of service by corrupting database contents or disrupting CMS operations. No known active exploitation in the wild has been reported to date. Organizations running this CMS should consider immediate mitigation steps or migration, as the lack of vendor response leaves systems exposed.

The SQL injection vulnerability in BiggiDroid Simple PHP CMS 1.0 can have serious consequences for organizations using this software. Successful exploitation can lead to unauthorized access to sensitive data stored in the CMS database, including potentially user credentials, site content, or configuration details. Attackers could modify or delete data, undermining data integrity and availability of the CMS. This could disrupt website operations, damage organizational reputation, and lead to regulatory compliance issues if sensitive data is exposed. Since the vulnerability requires authenticated access with high privileges, insider threats or compromised admin accounts pose a significant risk. The availability of public exploit code increases the likelihood of exploitation attempts, especially in environments where patching or mitigation is delayed. Organizations relying on this CMS for critical web presence or data management are at risk of targeted attacks, data breaches, and service disruptions.

To mitigate CVE-2025-15169, organizations should first restrict access to the /admin/editsite.php functionality to trusted administrators only, implementing strong authentication and network segmentation to reduce exposure. Since no official patch is available, applying web application firewall (WAF) rules to detect and block SQL injection patterns targeting the 'ID' parameter can provide temporary protection. Code-level mitigation involves reviewing and refactoring the vulnerable code to use parameterized queries or prepared statements, ensuring all user inputs are properly sanitized and validated. Regularly auditing and monitoring logs for suspicious activity related to the editsite.php endpoint is critical. Organizations should also consider migrating to alternative CMS platforms with active vendor support or newer versions if available. Finally, enforcing the principle of least privilege for admin accounts and using multi-factor authentication can reduce the risk of exploitation by compromised credentials.
