Executive Summary

Savon is a Ruby SOAP client library. The vulnerability exists in versions 0.9.8 through 2.17.2 where the Savon::Model.all_operations method uses attacker-controlled WSDL operation names in Ruby source code passed to module_eval. This allows arbitrary Ruby code execution within the application process.

Detection Guidance

To detect this vulnerability, check the installed version of the Savon gem. If it is between 0.9.8 and 2.17.1, the system is vulnerable. Run: gem list savon to verify the version. Update to version 2.17.2 or later to mitigate the issue.

Impact Analysis

An attacker could exploit this to execute malicious Ruby code in your application, potentially leading to data theft, system compromise, or unauthorized actions. The high CVSS score indicates significant risk as it requires no privileges or user interaction.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR's integrity and confidentiality requirements or HIPAA's security rules. Organizations using affected Savon versions may face compliance violations if exploited.

Mitigation Strategies

Upgrade Savon to version 2.17.2 or later to address the Ruby code execution vulnerability in Savon::Model.all_operations.
