CVE-2025-50490 is a vulnerability identified in the PHPGurukul Student Result Management System version 2.0, specifically within the /elms/emp-changepassword.php component. The issue stems from improper session invalidation during the password change process. When a user changes their password, the application fails to correctly invalidate the existing session or regenerate the session identifier. This flaw allows an attacker to hijack the session of a legitimate user by reusing or capturing the session token, potentially gaining unauthorized access to the victim's account. Session hijacking can lead to unauthorized access to sensitive student data, administrative functions, or other protected resources within the system. The vulnerability does not require user interaction beyond the victim performing a password change, and no authentication bypass is explicitly mentioned, but the attacker may need to have some level of access to intercept or reuse session tokens. No CVSS score is assigned yet, and no known exploits are reported in the wild. The lack of patch links indicates that a fix may not be publicly available at this time. Given the nature of the vulnerability, it is a classic web application security flaw related to session management, which is critical for maintaining user authentication integrity.

For European organizations, particularly educational institutions or entities using PHPGurukul Student Result Management System or similar platforms, this vulnerability poses a significant risk to confidentiality and integrity of student and staff data. Unauthorized session hijacking could allow attackers to impersonate users, access sensitive academic records, modify grades, or perform administrative actions. This could lead to data breaches, reputational damage, and potential regulatory non-compliance under GDPR due to exposure of personal data. The availability impact is less direct but could arise if attackers disrupt services or lock out legitimate users. Since the vulnerability is in a student management system, the impact is concentrated in the education sector but could extend to any organization using this software or similar vulnerable components. The risk is heightened in environments where session tokens are transmitted over insecure channels or where network monitoring is possible by attackers.

Organizations should immediately review their session management practices in the affected component and ensure that sessions are properly invalidated or regenerated upon password changes. Specifically, implement secure session invalidation by destroying the old session and issuing a new session identifier after password updates. Enforce secure cookie attributes such as HttpOnly and Secure flags to protect session tokens. Employ transport layer security (TLS) to encrypt all communications and prevent session token interception. Conduct thorough code reviews and penetration testing focused on session management. If possible, upgrade to a patched version of the software once available or apply vendor-provided fixes. Additionally, implement multi-factor authentication (MFA) to reduce the risk of session hijacking exploitation. Monitoring and logging session activities can help detect anomalous behavior indicative of hijacking attempts. User education on secure password practices and session security is also beneficial.
