A session hijacking vulnerability in PHPGurukul Online Course Registration v3.1 poses a significant risk of unauthorized account access.

This vulnerability involves improper session invalidation within the /crm/change-password.php component. An unauthenticated attacker can leverage this flaw to hijack active user sessions, potentially leading to unauthorized account access.

The vulnerability carries a CVSS score of 7.1, indicating a high level of risk to organizational security. Successful exploitation allows for session hijacking, which can lead to the compromise of sensitive user data, unauthorized administrative actions, and significant reputational damage.

Immediate Action: Since a specific patch version is not currently identified, administrators should restrict access to the affected CRM component and monitor for vendor updates on the official PHPGurukul website.

Proactive Monitoring: Review web server and application logs for suspicious access patterns to the /crm/change-password.php endpoint, particularly focusing on requests originating from unusual IP addresses.

Compensating Controls: Implement a Web Application Firewall (WAF) to filter malicious requests targeting the password change functionality and enforce strict session timeout policies to minimize the window for potential hijacking.

Public Exploit Available: Yes, a published proof-of-concept exists, attributed to the research write-up provided in the reference documentation.

Given the presence of a public proof-of-concept and the high severity of session hijacking, organizations using PHPGurukul Online Course Registration v3.1 must prioritize securing the affected environment. Administrators should verify if vendor patches are available and apply them immediately upon release, while ensuring that secondary controls such as WAF rules are active to mitigate the risk of exploitation.
