Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Ciborg, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

There is a /tmp file race condition in `chef/travis-cookbooks/ci_environment/perlbrew/recipes/default.rb` in the ciborg gem 3.0.0 when creating `/tmp/perlbrew-installer`. If a malicious local user creates the file first they can overwrite the contents with their own code executing it as the ciborg process owner.
