CVE-2023-26571
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 · uneditedMissing authentication in the SetStudentNotes method in IDAttend’s IDWeb application 3.1.052 and earlier allows modification of student data by unauthenticated attackers.

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 checksWork through these to decide whether this CVE applies to you.
-
Determine IDWeb versionCheck the application's About page, help menu, or examine version metadata in the IDWeb installation directory (typically found in assembly info, version.ini, or the main application's properties). Compare against the affected version range.Affected if The installed version is 3.1.052 or any earlier version.
-
Locate the SetStudentNotes API endpointReview application routing configuration, API documentation, or network traffic logs to identify the specific URL path for the SetStudentNotes method (commonly something like /api/studentnotes or /IDWeb/SetStudentNotes).Affected if The SetStudentNotes endpoint exists and is routable in the application.
-
Test endpoint authentication requirementSend a request to the SetStudentNotes endpoint without any authentication tokens, session cookies, or credentials. Observe the HTTP response code and whether the operation executes.Affected if The endpoint accepts and processes requests without requiring valid authentication.
-
Verify access control configurationExamine IDWeb configuration files (such as web.config, app.config, or role-based access settings) for authorization rules on the SetStudentNotes method. Check if any allow/anonymous access settings are present.Affected if No authorization rules are defined, or anonymous access is explicitly permitted for this method.
-
Check API security settingsReview the IDWeb API security configuration or middleware settings that govern which methods require authentication. Look for missing entries for SetStudentNotes in protected method lists.Affected if The SetStudentNotes method is absent from the protected/authenticated method registry.
If the IDWeb version is 3.1.052 or earlier AND the SetStudentNotes endpoint is accessible without authentication credentials, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper authentication and authorization checks on the SetStudentNotes method to ensure only authenticated users with appropriate privileges can modify student data.
