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
Insecure direct object reference (IDOR) vulnerability in Sergestec's Exito v8.0. This vulnerability allows an attacker to access data belonging to other customers through the 'id' parameter in '/admin/ticket_a4.php'.

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 · high confidence

An Insecure Direct Object Reference (IDOR) vulnerability in Sergestec Exito v8.0 allows unauthenticated attackers to access sensitive customer data by manipulating the 'id' parameter in the /admin/ticket_a4.php endpoint. The application fails to validate that the requesting user has permission to access the specific ticket record, enabling unauthorized cross-customer data exposure.

MitigationImplement proper object-level authorization checks to verify the current user owns or has permission to access the requested ticket before returning data. Consider replacing direct object references with indirect references (e.g., random tokens) to prevent enumeration attacks.

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 Sergestec Exito version
    Locate the Sergestec Exito installation and check the software version. Common locations: check application header/footer, look for version files in the web root, or query the application's 'About' page if available. Compare your installed version against version 8.0.
    Affected if Installed version is exactly 8.0
  2. Verify /admin/ticket_a4.php endpoint exists
    Check if the file ticket_a4.php exists in the /admin/ directory of the Sergestec Exito web application. Attempt to access it via HTTP GET request to determine if the endpoint responds.
    Affected if The endpoint responds (even with an error) indicating the file exists and is accessible
  3. Test unauthenticated access to the endpoint
    Send an HTTP GET request to /admin/ticket_a4.php without providing any authentication credentials or session cookies. Observe whether the application returns a login prompt or allows access.
    Affected if The endpoint accepts the request without requiring authentication (no redirect to login, no 401/403 response)
  4. Test IDOR via id parameter manipulation
    Send a request to /admin/ticket_a4.php with different integer values for the 'id' parameter (e.g., id=1, id=2, id=100). Compare whether different ticket records are returned or if access controls prevent viewing other tickets.
    Affected if Different 'id' values return different ticket data without any authorization check, indicating cross-customer data exposure is possible
  5. Check for proper authorization on ticket access
    If you have access to two different customer accounts, attempt to access a ticket belonging to one account while logged in as the other. Alternatively, inspect the application's response headers and session handling to see if any CSRF tokens or authorization headers are validated.
    Affected if The application returns ticket data for any id value regardless of user session ownership, confirming the IDOR vulnerability

If Sergestec Exito version 8.0 is installed AND the /admin/ticket_a4.php endpoint exists and accepts requests with manipulated 'id' parameters without proper ownership validation, the environment is affected by CVE-2025-41020.

Mitigation

Implement proper object-level authorization checks to verify the current user owns or has permission to access the requested ticket before returning data. Consider replacing direct object references with indirect references (e.g., random tokens) to prevent enumeration attacks.
