CVE-2025-15142 is a SQL injection vulnerability identified in the 9786 phpok3w web application, specifically within the show.php script. The vulnerability arises from improper sanitization of the ID parameter, allowing an attacker to inject malicious SQL queries remotely without requiring authentication or user interaction. This flaw can lead to unauthorized data disclosure, modification, or deletion, compromising the confidentiality, integrity, and availability of the backend database. The product uses a rolling release model, and the affected version is identified by a specific commit hash (901d96a06809fb28b17f3a4362c59e70411c933c), with no official patch or updated release available at the time of disclosure. Although no active exploitation in the wild has been reported, public exploit code exists, increasing the likelihood of attacks. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting medium severity due to its network attack vector, lack of required privileges or user interaction, and partial impact on data confidentiality, integrity, and availability. The vendor has been notified but has not yet responded or provided a fix. This vulnerability poses a significant risk to any organization using phpok3w, especially those hosting sensitive data or critical services.

For European organizations, this vulnerability can lead to unauthorized access to sensitive data, including personal, financial, or operational information stored in databases managed by phpok3w. Attackers exploiting this flaw could manipulate or delete data, disrupt services, or use the compromised system as a foothold for further attacks within the network. This is particularly concerning for sectors such as finance, healthcare, government, and e-commerce, where data integrity and confidentiality are paramount. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks, potentially leading to regulatory non-compliance under GDPR due to data breaches. Additionally, service disruptions could impact business continuity and reputation. The lack of an official patch necessitates immediate mitigation efforts to reduce exposure.

1. Implement immediate input validation and sanitization for the ID parameter in show.php, ensuring all inputs are strictly validated against expected formats and lengths. 2. Refactor the vulnerable code to use parameterized queries or prepared statements to prevent SQL injection. 3. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the ID parameter. 4. Monitor web server and database logs for suspicious activities indicative of SQL injection attempts. 5. Restrict database user privileges to the minimum necessary to limit the impact of a successful injection. 6. If possible, isolate the phpok3w application environment to reduce lateral movement risks. 7. Engage with the vendor or community to track patch releases or official fixes and apply them promptly once available. 8. Conduct security audits and penetration testing focusing on injection vulnerabilities in the application. 9. Educate development teams on secure coding practices to prevent similar vulnerabilities in future rolling releases.
