CVE-2019-6240
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 · uneditedAn issue was discovered in GitLab Community and Enterprise Edition before 11.4. It allows Directory Traversal.
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 confidenceA directory traversal vulnerability in GitLab Community and Enterprise Edition versions before 11.4 allows attackers to escape the intended directory and access files outside the web root by using path traversal sequences in input fields.

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.
-
Check GitLab version via command lineRun `sudo gitlab-ctl version` or `gitlab-rake gitlab:env:info` to display the installed GitLab version numberAffected if The displayed version is below 11.4.0
-
Check GitLab version via web interfaceLog into the GitLab admin area and navigate to the Admin Overview section or the help page (typically at /help) to view the running versionAffected if The shown version is below 11.4.0
-
Verify the exact version numberReview the full version string (e.g., 11.3.7, 11.2.5) to confirm it is less than 11.4.0 by comparing each numeric component in sequenceAffected if The version begins with 11.x where x is 3 or lower, or begins with any version number below 11
Your environment is affected if the installed GitLab version is any release prior to 11.4.0, since the directory traversal vulnerability exists in all earlier versions.

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 data11.4.0
Upgrade GitLab to version 11.4 or later to resolve the directory traversal vulnerability.
