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
Missing authentication in the GetLogFiles method in IDAttend’s IDWeb application 3.1.052 and earlier allows retrieval of sensitive log files by unauthenticated attackers.

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

The GetLogFiles method in IDAttend's IDWeb application 3.1.052 and earlier lacks authentication checks, enabling unauthenticated attackers to directly access and download sensitive log files that may contain credentials, session tokens, or system information.

MitigationApply vendor patch for IDWeb 3.1.052 or later; alternatively, implement authentication/authorization controls on the GetLogFiles method and consider network-level access restrictions until patch is available.

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. Identify IDWeb installation and version
    Locate the IDAttend IDWeb application installation directory or check the web application's version information (typically found in assembly metadata, about page, or configuration files)
    Affected if Installed version is 3.1.052 or earlier
  2. Confirm web service accessibility
    Determine if the IDWeb application is exposed via HTTP/HTTPS (check IIS configuration, web server settings, or firewall rules for port 80/443 or custom web ports)
    Affected if The IDWeb web interface is network-accessible
  3. Test GetLogFiles endpoint accessibility
    Attempt to access the GetLogFiles method endpoint (commonly at paths like /IDWeb/GetLogFiles or similar URL pattern under the IDWeb application root) without providing any authentication credentials
    Affected if The endpoint responds successfully and returns log file listings or contents without requiring login
  4. Inspect response for sensitive data exposure
    Examine the response from the GetLogFiles endpoint for indications that log files are being served - look for file names, paths, or actual log content in the HTTP response
    Affected if The response contains log file data, file names, or system information that should require authentication

Your environment is affected if IDAttend IDWeb version 3.1.052 or earlier is installed and the GetLogFiles web method is accessible without authentication credentials.

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 data
Upgrade available Upgrade to a release after 3.1.052
Interim mitigation
