CVE-2018-1103
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 · uneditedOpenshift Enterprise source-to-image before version 1.1.10 is vulnerable to an improper validation of user input. An attacker who could trick a user into using the command to copy files locally, from a pod, could override files outside of the target directory of the command.
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 confidenceOpenShift Enterprise source-to-image (S2I) before version 1.1.10 contains an improper input validation vulnerability allowing path traversal. An attacker who can trick a user into using the S2I copy command to copy files from a pod locally could potentially use directory traversal sequences (e.g., ../../../) to write files outside the intended target directory, leading to arbitrary file overwrite.

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.
-
Locate the s2i binary and determine its versionRun `s2i version` or `s2i --version` to display the installed Source-to-Image version numberAffected if The version displayed is less than 1.1.10 (for example, 1.1.9, 1.1.8, 1.1.6, etc.)
-
Verify s2i is installed on the systemCheck for the s2i executable in your PATH using `which s2i` or `command -v s2i`Affected if s2i is found and the version from step 1 is below 1.1.10
-
Confirm the s2i copy functionality is in useReview any build scripts, CI/CD pipelines, or manual commands that use `s2i copy` to copy artifacts from containers to the host filesystemAffected if s2i copy commands are being executed and the s2i version is below 1.1.10, allowing path traversal sequences to potentially write files outside the intended destination directory
You are affected if the s2i binary version is below 1.1.10 and you use the s2i copy command to extract files from pods to local directories.

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 data1.1.10
Upgrade OpenShift Enterprise source-to-image component to version 1.1.10 or later which includes proper path validation to prevent directory traversal.
