CVE-2021-41975
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 · uneditedTadTools special page is vulnerable to authorization bypass, thus remote attackers can use the specific parameter to delete arbitrary files in the system without logging in.
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 confidenceTadTools contains an authorization bypass vulnerability in a special page where a specific parameter allows remote attackers to delete arbitrary files in the system without authentication. The lack of proper access control checks enables unauthenticated file deletion through the vulnerable parameter.

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.
-
Confirm TadTools installationIdentify if TadTools software is present in your environment by locating its installation directory or checking installed packagesAffected if TadTools is found installed in the system
-
Determine installed versionLocate and read the version file or check the installed package version number to identify the exact version of TadToolsAffected if Installed version is 3.2.1 or lower (below 3.2.2)
-
Locate special page with file deletionFind the special page within the TadTools installation that contains file deletion functionalityAffected if The file deletion page exists in the installation
-
Verify unauthenticated access is possibleInspect the code on the special page to confirm the specific parameter allows file deletion without requiring authentication or authorization checksAffected if The parameter permits unauthenticated file deletion operations
Your environment is affected if TadTools version is below 3.2.2 and the vulnerable file deletion parameter on the special page is accessible without authentication.

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.
dbcve · scoped3.2.2
Implement proper authentication and authorization checks on the affected special page, specifically validating user permissions before allowing file deletion operations. Update to the latest patched version of TadTools if available.
TadTools 3.2.2
- Identify the current version of TadTools installed in the system
- Download TadTools version 3.2.2 or later from the official source
- Backup the current TadTools installation and database before upgrading
- Replace the existing TadTools files with version 3.2.2
- Verify the upgrade was successful by checking the version number
- Test that the authorization bypass vulnerability is no longer present by ensuring the specific parameter no longer allows unauthenticated file deletion
