CVE-2025-12248 identifies a SQL injection vulnerability in CLTPHP version 3.0, specifically within an unknown function in the /home/search.html file. The vulnerability arises from improper sanitization of the 'keyword' parameter, which is directly incorporated into SQL queries without adequate validation or parameterization. This allows an attacker to craft malicious input that alters the intended SQL command, potentially enabling unauthorized data access, data modification, or denial of service. The vulnerability is remotely exploitable without requiring authentication or user interaction, making it particularly dangerous. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the ease of exploitation and the limited but non-negligible impact on confidentiality, integrity, and availability. Although no known exploits are currently active in the wild, the public disclosure of the vulnerability increases the likelihood of exploitation attempts. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts by affected organizations. The vulnerability affects only version 3.0 of CLTPHP, a PHP-based web framework or CMS, commonly used in certain web applications. Attackers exploiting this flaw could extract sensitive information from the backend database, modify or delete data, or disrupt service availability, depending on the database privileges of the application. The absence of authentication requirements and user interaction lowers the barrier for exploitation, making this a significant risk for exposed web servers running the vulnerable software.

For European organizations, the impact of CVE-2025-12248 can be significant, particularly for those relying on CLTPHP 3.0 in their web infrastructure. Successful exploitation could lead to unauthorized disclosure of sensitive data, including customer information, internal records, or intellectual property, thereby violating GDPR and other data protection regulations. Data integrity could be compromised, resulting in corrupted or altered records that affect business operations and trustworthiness. Availability may also be impacted if attackers leverage the vulnerability to cause denial of service or disrupt database operations. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise without additional factors. However, the ease of remote exploitation without authentication increases the urgency for mitigation. European sectors such as finance, healthcare, and government, which often handle sensitive data and are subject to strict compliance requirements, could face regulatory penalties and reputational damage if exploited. The public disclosure and potential for automated exploit tools to emerge further elevate the risk. Organizations with internet-facing CLTPHP 3.0 installations are particularly vulnerable, especially if they lack robust web application firewalls or input validation controls.

To mitigate CVE-2025-12248, European organizations should first verify if they are running CLTPHP version 3.0 and identify any web applications utilizing the /home/search.html functionality. Immediate steps include implementing strict input validation and sanitization for the 'keyword' parameter to prevent malicious SQL code injection. Employing parameterized queries or prepared statements in the application code is critical to eliminate direct concatenation of user input into SQL commands. If patches or updates from the CLTPHP maintainers become available, organizations should prioritize applying them promptly. In the absence of official patches, deploying a Web Application Firewall (WAF) with custom rules to detect and block SQL injection patterns targeting the vulnerable endpoint can reduce risk. Regularly monitoring web server and database logs for unusual query patterns or errors indicative of injection attempts is recommended. Additionally, restricting database user privileges to the minimum necessary can limit the potential damage from exploitation. Organizations should also conduct security assessments and penetration testing focused on SQL injection vectors. Finally, educating developers and administrators about secure coding practices and the risks of unsanitized inputs will help prevent similar vulnerabilities in the future.
