Savon::Model evaluates WSDL operation names as Ruby source
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
`Savon::Model` generated SOAP operation methods by interpolating operation names into Ruby source passed to `module_eval`. An attacker who can control the operation names of a WSDL, can inject Ruby code that executes in the application process. This affects only the `.all_operations` class method provided by `Savon::Model` to automatically register all operations provided by the WSDL. Configuring `Savon::Model` with trusted operation names via `.operations` is safe.
### Patches
Patched in Savon 2.17.2.
Users should upgrade to 2.17.2 or later.
### Workarounds
Avoid `.all_operations` for untrusted WSDL documents. Use `.operations` with trusted operation names instead.
