CVE-2025-63955 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the manage-students.php component of PHPGurukul Student Record System version 3.2. CSRF vulnerabilities occur when a web application does not properly verify that requests to perform sensitive actions originate from legitimate users, allowing attackers to trick authenticated users into executing unwanted actions. In this case, an attacker can craft a malicious web page or link that, when visited by an authenticated administrator, causes the deletion of user accounts without their consent. This leads to a Denial of Service (DoS) condition by removing critical student records. The vulnerability is exploitable remotely over the network without requiring any authentication or user interaction beyond visiting a malicious URL. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) indicates network attack vector, low attack complexity, no privileges or user interaction required, unchanged scope, no impact on confidentiality or integrity, but high impact on availability. No patches or exploit code are currently publicly available, but the vulnerability is published and should be addressed promptly. The root cause is the lack of anti-CSRF protections such as tokens or origin checks in the affected PHP script. This vulnerability falls under CWE-352, which covers CSRF weaknesses. Organizations using PHPGurukul Student Record System v3.2 should prioritize mitigation to prevent unauthorized account deletions and service disruption.

The primary impact of CVE-2025-63955 is a Denial of Service (DoS) through unauthorized deletion of user accounts, which can disrupt educational operations by removing critical student data. For European organizations, especially educational institutions relying on PHPGurukul Student Record System, this can lead to significant operational downtime, data loss, and administrative overhead to restore accounts and records. The absence of confidentiality or integrity impact reduces risks of data leakage or tampering, but availability loss can affect compliance with data protection regulations such as GDPR if student records are lost or inaccessible. The vulnerability's ease of exploitation without authentication or user interaction increases the risk of widespread attacks if exploited in the wild. This can also damage institutional reputation and trust. The lack of known exploits currently limits immediate threat but does not reduce the urgency for mitigation given the high CVSS score and potential for automated attacks.

To mitigate CVE-2025-63955, organizations should implement robust anti-CSRF protections in the PHPGurukul Student Record System. This includes adding unique, unpredictable CSRF tokens to all state-changing requests and validating these tokens server-side before processing. Additionally, verifying the HTTP Referer or Origin headers can help confirm request legitimacy. Restricting administrative access to trusted networks or VPNs can reduce exposure. Regularly auditing and updating the PHPGurukul system to the latest secure versions, once patches are available, is critical. Employing web application firewalls (WAFs) with rules to detect and block CSRF attack patterns can provide an additional defense layer. User training for administrators to avoid clicking suspicious links and monitoring logs for unusual deletion activities will aid early detection. Backup and recovery plans should be tested to ensure rapid restoration of deleted accounts if an attack occurs.
