The flaw exists in the \u003ccode\u003e.all_operations\u003c/code\u003e class method, which is designed to automatically register SOAP operations by parsing a WSDL document. During this process, the library interpolates operation names directly into a string that is passed to Ruby's \u003ccode\u003emodule_eval\u003c/code\u003e function. An attacker capable of influencing the WSDL source (e.g., providing a URL to a malicious WSDL file or intercepting a legitimate service response) can inject arbitrary Ruby code. This code executes with the privileges of the application process. The vulnerability affects all versions of the \u003ccode\u003esavon\u003c/code\u003e gem from 0.9.8 up to 2.17.2. Applications that manually define operations via the \u003ccode\u003e.operations\u003c/code\u003e method are not affected, as this approach avoids the insecure string evaluation of untrusted metadata.\u003c/p\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation allows for full remote code execution within the context of the Ruby application process. Depending on the environment, this could lead to sensitive data exfiltration, unauthorized modification of application logic, or complete system compromise.
