A session invalidation vulnerability in PHPGurukul Small CRM v3.0 exposes users to potential session hijacking attacks.

The application fails to properly invalidate sessions within the /crm/change-password.php component. This flaw can be triggered by an unauthenticated attacker to hijack active user sessions.

The ability for an attacker to hijack a user session poses a severe risk to data confidentiality and integrity. With a CVSS score of 7.1, this vulnerability is classified as High, as it could allow unauthorized access to sensitive CRM data and administrative functions without requiring prior authentication.

Immediate Action: Since no official patch is currently available, administrators should restrict access to the /crm/change-password.php endpoint or consider disabling the affected functionality until a vendor update is released.

Proactive Monitoring: Review web access logs for unusual patterns or suspicious requests targeting the /crm/change-password.php file, particularly those originating from unknown or unauthorized IP addresses.

Compensating Controls: Deploy a Web Application Firewall (WAF) to filter and block malicious traffic patterns directed at the vulnerable CRM component.

Public Exploit Available: Yes, a proof-of-concept exists as detailed in the GitHub repository referenced in the CVE record.

Given the High severity and the existence of a public proof-of-concept, organizations using PHPGurukul Small CRM v3.0 must prioritize mitigating this exposure. Administrators should actively monitor for vendor security updates and apply them immediately upon release to remediate the underlying session handling logic.
