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
C-Kermit (aka ckermit) through 10.0 Beta.12 (aka 416-beta12) before 244644d allows a remote Kermit system to overwrite files on the local system, or retrieve arbitrary files from the local 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
How this class of weakness works · CWE-862

The application checks who you are but not whether you're allowed to perform a given action, so any authenticated user can reach things meant for others. This is the classic “change the ID in the URL” bug. The fix is an authorization check on every request, evaluated against the acting user's permissions.

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.

Recommended fix Moderate confidence

Any version after commit 244644d (the description indicates versions through 10.0 Beta.12/416-beta12 are affected, and the fix is present in commits following 244644d)

  1. Obtain the patched version from the repository after commit 244644d, either by cloning the updated repository or applying the fix from pull request #20 at https://github.com/KermitProject/ckermit/pull/20
  2. If building from source, ensure you are using a version that includes the fix (any version after commit 244644d)
  3. Alternatively, check if your Linux distribution has issued a security update for the ckermit package
  4. Recompile and redeploy the updated ckermit binary to all affected systems
