CVE-2025-50485 is a vulnerability identified in the PHPGurukul Online Course Registration system version 3.1, specifically within the /crm/change-password.php component. The issue stems from improper session invalidation after a password change operation. When a user changes their password, the application fails to properly invalidate or regenerate the session identifier associated with the user's session. This flaw allows an attacker who has obtained or intercepted a valid session token prior to the password change to continue using that session token to impersonate the legitimate user, effectively executing a session hijacking attack. Session hijacking can lead to unauthorized access to user accounts, exposing sensitive personal information, course registration data, and potentially administrative functions depending on the user's privileges. The vulnerability does not require user interaction beyond the password change process and does not currently have any known exploits in the wild. However, the absence of a patch or mitigation guidance in the provided data suggests that the vulnerability remains unaddressed in the affected version. The lack of a CVSS score indicates that the severity has not been formally assessed, but the nature of session hijacking vulnerabilities typically poses a significant risk to confidentiality and integrity of user sessions. The vulnerability is particularly critical in web applications handling sensitive user data and authentication workflows, such as educational platforms that manage personal and academic information.

For European organizations using PHPGurukul Online Course Registration v3.1, this vulnerability could lead to unauthorized access to user accounts, including student and administrative profiles. This unauthorized access can result in data breaches involving personal identifiable information (PII), academic records, and potentially financial information if payment details are integrated. Such breaches could violate the EU's General Data Protection Regulation (GDPR), leading to legal and financial repercussions. Additionally, session hijacking could allow attackers to manipulate course registrations, disrupt educational services, or escalate privileges within the system. The impact extends beyond confidentiality to integrity and availability, as attackers might alter or delete records or disrupt normal operations. Given the increasing reliance on online educational platforms in Europe, especially post-pandemic, this vulnerability poses a tangible risk to institutional reputation and operational continuity.

European organizations should immediately audit their PHPGurukul Online Course Registration deployments to identify affected versions. Since no official patch links are provided, organizations should implement the following mitigations: 1) Enforce session invalidation and regeneration upon password changes by modifying the application code to destroy existing sessions and issue new session tokens. 2) Implement secure session management practices such as setting the 'HttpOnly' and 'Secure' flags on cookies, and using short session timeouts. 3) Monitor and log session activities to detect anomalies indicative of session hijacking attempts. 4) Educate users to log out and close browsers after password changes. 5) If possible, upgrade to a newer, patched version of the software once available or consider alternative platforms with robust security controls. 6) Employ web application firewalls (WAFs) to detect and block suspicious session-related activities. 7) Conduct regular security assessments and penetration testing focusing on session management.
