CVE-2025-4874 is a SQL Injection vulnerability identified in the PHPGurukul News Portal Project version 4.1, specifically within the /admin/contactus.php file. The vulnerability arises from improper sanitization or validation of the 'pagetitle' parameter, which is directly used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to the backend database. This can lead to unauthorized data disclosure, data modification, or even complete compromise of the database server. The vulnerability requires no authentication or user interaction, making it exploitable by any remote attacker with network access to the affected application. Although the CVSS 4.0 score is 6.9 (medium severity), the impact on confidentiality, integrity, and availability can be significant depending on the database contents and the deployment context. No official patches have been linked yet, and while no known exploits are currently reported in the wild, the public disclosure of the vulnerability increases the risk of exploitation attempts.

For European organizations using the PHPGurukul News Portal Project 4.1, this vulnerability poses a significant risk to the confidentiality and integrity of their data. News portals often handle sensitive user information, editorial content, and possibly subscriber data. Exploitation could lead to unauthorized data leakage, defacement of news content, or disruption of service, damaging organizational reputation and trust. Additionally, compromised portals could be used as a pivot point for further attacks within the network. Given the remote, unauthenticated nature of the exploit, attackers can easily target exposed installations. This is particularly concerning for media organizations, educational institutions, and government agencies in Europe that rely on this software for public communication. The lack of a patch increases the urgency for mitigation to prevent potential data breaches and service interruptions.

1. Immediate mitigation should include implementing Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the 'pagetitle' parameter in /admin/contactus.php. 2. Apply input validation and sanitization on the 'pagetitle' parameter, ensuring that only expected characters and formats are accepted. 3. Employ parameterized queries or prepared statements in the backend code to prevent direct injection of user input into SQL commands. 4. Restrict access to the /admin directory by IP whitelisting or VPN-only access to reduce exposure. 5. Monitor application logs for suspicious query patterns or repeated access attempts to the vulnerable endpoint. 6. Engage with PHPGurukul or the software maintainers to obtain or request an official patch or update. 7. As a temporary measure, consider disabling the vulnerable functionality if feasible without impacting critical operations. 8. Conduct a thorough security review of the entire application to identify and remediate other potential injection points.
