Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
This vulnerability exists in e-Sushrut due to improper authorization checks during resource access. An authenticated attacker could exploit this vulnerability by manipulating encoded parameters in the request URL to gain unauthorized access to patient accounts on the targeted system.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is an Insecure Direct Object Reference (IDOR) vulnerability in e-Sushrut where the application fails to properly validate authorization when accessing patient records. An authenticated attacker can manipulate encoded parameters in request URLs to bypass access controls and view unauthorized patient data.

MitigationImplement proper authorization checks on all endpoints that access patient data, verifying that the authenticated user has permission to access the specific resource before returning any information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm e-Sushrut deployment
    Identify if e-Sushrut or a related healthcare application is installed. Check application login pages, headers, or system identifiers for 'e-Sushrut' branding. Review installed software inventories or web application directories for e-Sushrut components.
    Affected if e-Sushrut is not present in the environment, so this CVE does not apply
  2. Verify authenticated access to patient records
    Log in to the e-Sushrut application with a valid user account. Navigate to patient record lookup or viewing features. Confirm the application exposes endpoints or functions that return patient data to authenticated users.
    Affected if The patient record access functionality is not available or not accessible to the authenticated user role being tested
  3. Test for IDOR via parameter tampering
    Using a web proxy or browser developer tools, capture a request when accessing a patient record. Identify the parameter carrying the patient identifier (often encoded or encrypted). Modify this parameter to reference a different patient ID while keeping the session authenticated. Submit the modified request and observe the response.
    Affected if The application returns patient data for a different patient than the one originally requested, indicating no proper ownership verification
  4. Check authorization logic on patient data endpoints
    Examine the application's behavior when requesting patient records belonging to other users or departments. Verify if the server validates user permissions before returning data. Look for consistent authorization checks across different patient record access points.
    Affected if The application returns patient information without verifying that the authenticated user has permission to access that specific record

The environment is affected if e-Sushrut is deployed and allows an authenticated user to view patient records by manipulating encoded parameters in requests without proper authorization validation.
