echor fixed: Latest secure release 
Upgrade echor to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for echor

How to Check if You Are Affected

To determine whether your application is affected by CVE-2014-1834, inspect your project dependencies for Echor:

inspect dependencies for echor

Note: Verify declared build manifests and deployed runtime container environments.

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 Echor, 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 `perform_request` function in `/lib/echor/backplane.rb` in echor 0.1.6 Ruby Gem allows local users to inject arbitrary code by adding a semi-colon in their username or password.
