How to Fix CVE-2013-1756

To remediate this vulnerability, upgrade all affected Dragonfly dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

dragonfly fixed: 0.8.6 
Upgrade dragonfly to 0.8.6
dragonfly fixed: 0.9.13 
Upgrade dragonfly to 0.9.13
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 dragonfly

How to Check if You Are Affected

To determine whether your application is affected by CVE-2013-1756, inspect your project dependencies for Dragonfly:

inspect dependencies for dragonfly

Analyze the terminal output to locate any version of Dragonfly in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.8.6), your application is affected.

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

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 Dragonfly, 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 Dragonfly gem 0.7 before 0.8.6 and 0.9.x before 0.9.13 for Ruby, when used with Ruby on Rails, allows remote attackers to execute arbitrary code via a crafted request.
