Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Rest client, 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 rest-client gem 1.6.10 through 1.6.13 for Ruby, as distributed on RubyGems.org, included a code-execution backdoor inserted by a third party. Users of an affected version should consider downgrading to the last non-affected version of 1.6.9, or upgrading to 1.7.x. Additionally, a set of other minor gems have been partially or completely yanked and are included in this advisory. These include cron_parser, coin_base, blockchain_wallet, awesome-bot, doge-coin, capistrano-colors, bitcoin_vanity, lita_coin, coming-soon, and omniauth_amazon.
