CVE-2025-6332 is a SQL Injection vulnerability identified in version 2.0 of the PHPGurukul Directory Management System, specifically within the /admin/manage-directory.php file. The vulnerability arises from improper sanitization of the 'del' parameter, which is used in SQL queries without adequate validation or parameterization. This flaw allows an unauthenticated remote attacker to inject arbitrary SQL commands by manipulating the 'del' argument, potentially leading to unauthorized access, data leakage, modification, or deletion within the underlying database. The vulnerability does not require user interaction or prior authentication, increasing its risk profile. Although the CVSS 4.0 score is 5.3 (medium severity), the vulnerability's characteristics—remote exploitability, lack of authentication, and direct database manipulation—indicate a significant threat vector. The vulnerability affects only version 2.0 of the product, and no official patches or mitigations have been published at the time of analysis. No known exploits have been observed in the wild yet, but public disclosure of the exploit code increases the likelihood of exploitation attempts. The vulnerability impacts confidentiality, integrity, and availability of data managed by the Directory Management System, which is often used to organize and maintain critical organizational contact and resource information. Given the administrative context of the vulnerable script, successful exploitation could lead to full compromise of the directory data and potentially lateral movement within the affected environment.

For European organizations using PHPGurukul Directory Management System 2.0, this vulnerability poses a considerable risk. The directory system often contains sensitive organizational data such as employee details, contact information, and resource allocations. Exploitation could lead to unauthorized disclosure of sensitive information, manipulation or deletion of directory entries, and disruption of administrative operations. This could impact business continuity, regulatory compliance (e.g., GDPR), and trustworthiness of internal systems. Additionally, attackers could leverage this vulnerability as a foothold to escalate privileges or move laterally within the network, increasing the risk of broader compromise. The medium CVSS score may underestimate the real-world impact, especially in environments where directory data is critical. Organizations in sectors with strict data protection requirements or those relying heavily on PHPGurukul products for internal management are particularly vulnerable. The lack of authentication requirement and remote exploitability further exacerbate the threat, enabling attackers to target exposed management interfaces directly.

1. Immediate mitigation should include restricting access to the /admin/manage-directory.php endpoint via network controls such as IP whitelisting or VPN-only access to limit exposure to trusted administrators. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'del' parameter, including pattern-based and anomaly detection rules. 3. Conduct a thorough code review and refactor the affected code to use parameterized queries or prepared statements to eliminate SQL injection vectors. 4. If possible, upgrade to a patched version of the PHPGurukul Directory Management System once available; if no patch exists, consider disabling the vulnerable functionality temporarily. 5. Monitor logs for suspicious activity related to the 'del' parameter or unusual database queries to detect exploitation attempts early. 6. Educate administrators on the risks of exposing management interfaces publicly and enforce strong authentication and access controls. 7. Perform regular security assessments and penetration testing focusing on injection vulnerabilities in custom or third-party web applications. These measures go beyond generic advice by focusing on immediate access restriction, targeted WAF tuning, and proactive monitoring tailored to the specific vulnerable parameter and endpoint.
