Name of the Vulnerable Software and Affected Versions aws-lambda versions prior to 1.0.5

Description The issue allows a user to inject arbitrary commands into the zipCmd used within the config.FunctionName due to a lack of sanitization of the config.FunctionName when constructing the argument for the exec function.

Recommendations For versions prior to 1.0.5, update to version 1.0.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the config.FunctionName to minimize the risk of exploitation. Avoid using the config.FunctionName to construct arguments for the exec function until the issue is resolved.
