CVE-2025-5251 is a SQL Injection vulnerability identified in version 4.1 of the PHPGurukul News Portal Project, specifically within the /admin/edit-subcategory.php file. The vulnerability arises from improper sanitization or validation of the 'Category' parameter, which can be manipulated by an attacker to inject malicious SQL code. This injection flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands on the backend database. The vulnerability does not require any privileges or user interaction, making it accessible to any remote attacker who can reach the vulnerable endpoint. Exploiting this vulnerability could lead to unauthorized data disclosure, data modification, or even complete compromise of the database integrity and availability. Although the CVSS 4.0 base score is 6.9 (medium severity), the potential impact on confidentiality, integrity, and availability is significant due to the nature of SQL Injection attacks. No official patches or fixes have been disclosed yet, and while there are no known exploits in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The vulnerability affects a specific version (4.1) of the PHPGurukul News Portal Project, a web-based content management system for news publishing, which is typically deployed on web servers running PHP and connected to relational databases such as MySQL or MariaDB.

For European organizations using the PHPGurukul News Portal Project 4.1, this vulnerability poses a critical risk to the confidentiality and integrity of their news content and potentially sensitive user data stored in the backend database. Successful exploitation could allow attackers to extract sensitive information, modify or delete news categories or articles, and disrupt the availability of the news portal. This could lead to reputational damage, loss of user trust, and regulatory compliance issues, especially under GDPR if personal data is exposed. Since the vulnerability is remotely exploitable without authentication, attackers could leverage automated tools to scan and compromise vulnerable installations across Europe. The impact is particularly severe for media companies, news agencies, and organizations relying on this CMS for public communication, as defacement or misinformation injection could have broader societal consequences. Additionally, compromised portals could be used as a foothold for further network intrusion or to distribute malware.

Immediate mitigation steps include implementing input validation and parameterized queries or prepared statements in the /admin/edit-subcategory.php script to prevent SQL injection. Organizations should audit their PHPGurukul News Portal installations and upgrade to a patched version once available. In the absence of an official patch, applying Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'Category' parameter can reduce risk. Restricting access to the /admin directory via IP whitelisting or VPN can limit exposure. Regularly monitoring web server logs for suspicious requests targeting the vulnerable parameter is advised. Additionally, database user permissions should be minimized to limit the impact of a successful injection. Backup procedures should be verified to ensure rapid recovery in case of data tampering. Organizations should also consider isolating the CMS environment to reduce lateral movement risks.
