CVE-2025-6300 is a critical SQL Injection vulnerability identified in version 1.3 of the PHPGurukul Employee Record Management System, specifically within the /admin/editempeducation.php file. The vulnerability arises due to improper sanitization or validation of the 'yopgra' parameter, which is directly used in SQL queries without adequate escaping or parameterization. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially manipulating the backend database. Exploitation can lead to unauthorized data access, modification, or deletion, compromising the confidentiality, integrity, and availability of employee records stored within the system. The vulnerability requires no authentication or user interaction, increasing its risk profile. Although the CVSS 4.0 score is 6.9 (medium severity), the nature of SQL injection vulnerabilities typically warrants heightened attention due to their potential for data exfiltration and system compromise. No official patches have been released yet, and while no known exploits are currently active in the wild, public disclosure of the exploit code increases the likelihood of imminent attacks. The vulnerability affects only version 1.3 of the product, which is a specialized employee record management system primarily used by organizations to manage sensitive HR data.

For European organizations using PHPGurukul Employee Record Management System 1.3, this vulnerability poses a significant risk to the confidentiality and integrity of employee data, including personal identification information, employment history, and possibly payroll details. Successful exploitation could lead to data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and operational disruptions. Given the remote and unauthenticated nature of the attack, threat actors could exploit this vulnerability to gain unauthorized access to sensitive HR databases without insider privileges. This could facilitate insider threat scenarios, data manipulation, or lateral movement within the network. Additionally, the potential for data deletion or corruption could disrupt HR operations, impacting payroll processing and employee management. The medium CVSS score may underestimate the real-world impact, especially considering the sensitivity of employee data and strict European data protection laws. Organizations in sectors with high regulatory scrutiny, such as finance, healthcare, and government, may face amplified consequences.

1. Immediate mitigation should focus on implementing input validation and prepared statements or parameterized queries for the 'yopgra' parameter in /admin/editempeducation.php to prevent SQL injection. 2. If source code modification is not immediately feasible, deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting this parameter. 3. Conduct a thorough audit of all input handling in the application to identify and remediate similar injection points. 4. Restrict access to the /admin directory through network segmentation and IP whitelisting to limit exposure. 5. Monitor logs for suspicious database query patterns or repeated access attempts to the vulnerable endpoint. 6. Plan and prioritize upgrading to a patched version once available or consider migrating to alternative employee management solutions with secure coding practices. 7. Educate internal security teams about this vulnerability and ensure incident response plans include scenarios involving SQL injection attacks on HR systems. 8. Regularly back up employee data with integrity checks to enable recovery in case of data tampering or deletion.
