Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In Colorscore, 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 initialize method in the Histogram class in `lib/colorscore/histogram.rb` in the colorscore gem before 0.0.5 for Ruby allows context-dependent attackers to execute arbitrary code via shell metacharacters in the (1) `image_path`, (2) `colors`, or (3) `depth` variable.
