Executive Summary

CVE-2025-70064 is a privilege escalation vulnerability in PHPGurukul Hospital Management System v4.0. A low-privileged user, such as a patient who self-registers, can bypass access controls by manually navigating to the /admin/ directory after logging in. This allows the user to access the Administrator Dashboard and all its sub-modules without proper authorization.

Essentially, the system does not properly restrict access to administrative functions, enabling any self-registered user to elevate their privileges from a patient to an administrator simply by manipulating the URL.

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by attempting to access the /admin/ directory after logging in as a low-privileged user (Patient). If the user can access the Administrator Dashboard and its sub-modules by manually browsing to /admin/, the system is vulnerable.'}, {'type': 'paragraph', 'content': 'A practical detection method involves registering a new user through the self-registration process, logging in as that user, and then trying to access the /admin/ URL directly.'}, {'type': 'paragraph', 'content': 'While no specific commands are provided, a simple approach using curl or a web browser to test URL access can be used, for example:'}, {'type': 'list_item', 'content': 'curl -i -c cookies.txt -d "username=newuser&password=pass" http://targetsite/register'}, {'type': 'list_item', 'content': 'curl -i -b cookies.txt http://targetsite/admin/'}, {'type': 'paragraph', 'content': 'If the /admin/ page is accessible with the low-privileged user session cookies, the vulnerability exists.'}] [1]

Mitigation Strategies

Immediate mitigation steps include restricting access to the /admin/ directory to only authorized administrator accounts and implementing proper authorization checks on the server side.

Ensure that low-privileged users cannot access administrative URLs by enforcing role-based access control (RBAC) and validating user permissions on every request.

Additionally, review and patch the application to fix the privilege escalation flaw, and consider disabling or securing the self-registration feature until the issue is resolved.
