Account hijacking via fixed session identifiers
Published Jul 28, 2025 · Updated Jul 5, 2026
Session fixation in PHPGurukul Online Course Registration 3.1 allows remote attackers to hijack user accounts through change-password.php. The password-change flow accepts an attacker-chosen or captured session identifier and does not replace it when the victim authenticates. Exploitation requires the victim to authenticate with the attacker-fixed token, after which the attacker can access the account and change its password.
