CVE-2025-6912 is a SQL Injection vulnerability identified in version 3.2 of the PHPGurukul Student Record System, specifically within the /manage-students.php file. The vulnerability arises from improper sanitization or validation of the 'del' parameter, which is used in some unknown processing logic. An attacker can manipulate this parameter to inject malicious SQL code, potentially altering the intended database queries. This can lead to unauthorized data access, data modification, or even deletion of records within the student record system database. The vulnerability is remotely exploitable without requiring user interaction or authentication, increasing its risk profile. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the fact that while the attack vector is network-based and requires no privileges or user interaction, the impact on confidentiality, integrity, and availability is limited to low levels. The vulnerability has been publicly disclosed, but there are no known exploits currently observed in the wild. The lack of available patches or official vendor fixes at this time means that affected systems remain vulnerable. Given the critical nature of student record systems, which often contain sensitive personal and academic data, exploitation could lead to privacy breaches and data integrity issues. However, the limited impact rating suggests that the vulnerability may not allow full database compromise or system takeover, but rather partial data exposure or modification.

For European organizations, particularly educational institutions using PHPGurukul Student Record System 3.2, this vulnerability poses a risk to the confidentiality and integrity of student data. Exploitation could result in unauthorized disclosure of personal information, academic records, or administrative data, potentially violating GDPR requirements and leading to regulatory penalties. Data tampering could undermine the trustworthiness of academic records and disrupt administrative processes. Although the CVSS score indicates medium severity, the sensitivity of educational data and the regulatory environment in Europe elevate the potential impact. Additionally, if attackers leverage this vulnerability as a foothold, it could be a stepping stone for further attacks within the network. The absence of known exploits in the wild currently reduces immediate risk, but the public disclosure increases the likelihood of future exploitation attempts. Organizations may also face reputational damage if breaches occur due to this vulnerability.

Given the absence of official patches, European organizations should implement immediate compensating controls. These include: 1) Conducting a thorough code review and applying input validation and parameterized queries or prepared statements to the 'del' parameter in /manage-students.php to prevent SQL injection. 2) Employing Web Application Firewalls (WAFs) with rules specifically targeting SQL injection patterns to detect and block malicious requests targeting the vulnerable parameter. 3) Restricting database user privileges associated with the application to the minimum necessary, limiting the potential damage from injection attacks. 4) Monitoring application logs and network traffic for unusual activities or repeated attempts to exploit the 'del' parameter. 5) Isolating the student record system within a segmented network zone to reduce lateral movement risk. 6) Preparing incident response plans tailored to potential data breaches involving student records. 7) Engaging with the vendor or community to obtain or develop patches or updates addressing this vulnerability. These steps go beyond generic advice by focusing on immediate practical controls and proactive monitoring specific to this vulnerability's characteristics.
