CVE-2014-5003
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 · uneditedchef/travis-cookbooks/ci_environment/perlbrew/recipes/default.rb in the ciborg gem 3.0.0 for Ruby allows local users to write to arbitrary files and gain privileges via a symlink attack on /tmp/perlbrew-installer.
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 confidenceThe ciborg gem 3.0.0 contains a symlink attack vulnerability in its perlbrew recipe. The installer script at /tmp/perlbrew-installer does not verify whether the target file is a symlink before writing, allowing a local attacker to create a malicious symlink and overwrite arbitrary files with root privileges.

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 if ciborg gem is installedRun `gem list ciborg` or `gem info ciborg` to see if the gem is present on the systemAffected if The ciborg gem is installed and version is 3.0.0
-
Verify ciborg version is exactly 3.0.0Run `gem list ciborg` and check the version column, or use `gem info ciborg` to get detailed version informationAffected if Version displayed is exactly 3.0.0 (older versions like 2.x are not affected, later versions may have fixes)
-
Check for perlbrew recipe usage in ciborgSearch for perlbrew-related files or configurations in the ciborg installation: `find $(gem which ciborg 2>/dev/null | xargs dirname) -name '*perlbrew*' 2>/dev/null`Affected if Perlbrew recipe files exist within the ciborg gem directory, indicating the vulnerable component is present
-
Inspect /tmp for perlbrew-installer scriptCheck if the file /tmp/perlbrew-installer exists: `ls -la /tmp/perlbrew-installer`Affected if The file /tmp/perlbrew-installer exists on the system, indicating the vulnerable installer script was or is in use
Environment is affected if ciborg gem version 3.0.0 is installed and the perlbrew recipe component is present or has been executed, allowing a symlink attack in /tmp.
Generated from the published advisory. Verify against your own configuration.
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 dataReplace insecure /tmp file usage with secure temporary file handling (e.g., use Ruby's Dir.mktmpdir or ensure proper symlink checks and restrictive permissions on /tmp). Ensure the perlbrew installer script uses safe temporary file operations.
