CVE-2025-6333 is a SQL Injection vulnerability identified in PHPGurukul Directory Management System version 2.0, specifically within the /admin/admin-profile.php file. The vulnerability arises due to improper sanitization or validation of the 'adminname' parameter, which can be manipulated remotely by an attacker to inject malicious SQL queries. This flaw allows an unauthenticated attacker to execute arbitrary SQL commands against the backend database without requiring user interaction or prior authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:L). The vulnerability has a CVSS 4.0 base score of 5.3, categorized as medium severity, reflecting limited impact on confidentiality, integrity, and availability, and requiring low privileges (likely a low-level authenticated user) for exploitation. However, the description states that the attack can be initiated remotely, which may imply that the attacker needs at least some form of access or that the privilege requirement is minimal. The vulnerability affects an administrative interface, which typically holds sensitive data and elevated privileges, increasing the risk if exploited. No official patches or fixes have been published yet, and no known exploits are currently observed in the wild, though public disclosure of the exploit code exists, increasing the risk of future exploitation. The vulnerability does not affect the scope beyond the vulnerable version 2.0 of the PHPGurukul Directory Management System. Given the nature of SQL Injection, successful exploitation could lead to unauthorized data access, data modification, or even complete compromise of the backend database, depending on the database permissions and configuration. The lack of user interaction and remote exploitability make this vulnerability a significant concern for organizations using this software in their administrative environments.

For European organizations using PHPGurukul Directory Management System 2.0, this vulnerability poses a tangible risk to the confidentiality and integrity of their directory data, which may include sensitive employee or organizational information. Exploitation could lead to unauthorized data disclosure, data tampering, or disruption of directory services, potentially impacting business operations and compliance with data protection regulations such as GDPR. Since the vulnerability affects an administrative interface, attackers gaining access could escalate privileges or pivot to other internal systems. The medium CVSS score reflects some limitations in impact scope, but the presence of publicly available exploit code increases the likelihood of targeted attacks. Organizations in sectors with high regulatory scrutiny or those relying heavily on directory management for identity and access control are particularly at risk. Additionally, if the directory system integrates with other critical infrastructure, the impact could cascade, affecting availability and operational continuity.

1. Immediate mitigation should include restricting access to the /admin/admin-profile.php interface via network-level controls such as IP whitelisting or VPN access to limit exposure to trusted personnel only. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection patterns targeting the 'adminname' parameter. 3. Conduct a thorough code review and apply proper input validation and parameterized queries (prepared statements) to eliminate SQL injection vulnerabilities in the affected code. 4. Monitor logs for unusual or suspicious SQL query patterns or repeated access attempts to the admin interface. 5. If possible, upgrade or patch the PHPGurukul Directory Management System once an official fix is released by the vendor. 6. As a temporary workaround, consider disabling or limiting the functionality of the vulnerable admin-profile.php page if it is not critical for immediate operations. 7. Educate administrators about the risks and encourage strong authentication mechanisms and session management to reduce the risk of privilege escalation. 8. Regularly back up directory data and test restoration procedures to mitigate potential data loss or corruption from exploitation.
