How to Fix CVE-2006-4111

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

rails fixed: 1.1.6 
Upgrade rails to 1.1.6
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 rails

How to Check if You Are Affected

To determine whether your application is affected by CVE-2006-4111, inspect your project dependencies for Rails:

inspect dependencies for rails

Analyze the terminal output to locate any version of Rails in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.6), 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 Rails, 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

Ruby on Rails before 1.1.5 allows remote attackers to execute Ruby code with "severe" or "serious" impact via a File Upload request with an HTTP header that modifies the LOAD_PATH variable, a different vulnerability than CVE-2006-4112.
