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 Gitlab grit, 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

The Grit gem for Ruby, as used in GitLab 5.2 before 5.4.1 and 6.x before 6.2.3, allows remote authenticated users to execute arbitrary commands, as demonstrated by the search box for the GitLab code search feature. GitLab Grit Gem for Ruby contains a flaw in the app/contexts/search_context.rb script. The issue is triggered when input passed via the code search box is not properly sanitized, which allows strings to be evaluated by the shell. This may allow a remote attacker to execute arbitrary commands.
