Description
Amazon Web Services (AWS) is a popular tool that provides multiple options for configuring and managing computing power, database storage, content delivery, and others through the AWS CLI. How can I set up Fiddler Everywhere to capture and decrypt HTTPS requests made from the AWS CLI?
Solution
Configuring the AWS CLI alongside Fiddler Everywhere
To capture traffic generated from AWS CLI commands, you need to configure the Fiddler Proxy for the preferred terminal application (where AWS CLI will be executed) and configure the AWS_CA_BUNDLE environment variable for the certificate bundle that will be used for HTTPS certificate validation.
Open the terminal application where the AWS CLI commands will run. Set the terminal application to use the Fiddler Everywhere proxy, as described in this KB article.
Open Fiddler Everywhere and export the
Fiddler_Root_Certificate_Authority.crtfile through Settings > HTTPS > Advanced Settings > Export root certificate(PEM/ASCII format) (note that this is not the default option from the drop-down menu). The certificate is exported to ~/Desktop as file with name Fiddler_Root_Certificate_Authority.pem.-
Use the exported PEM file to set the
AWS_CA_BUNDLEenvironment variable. TheAWS_CA_BUNDLEspecifies the path to a certificate bundle to use for HTTPS certificate validation. If defined, this environment variable overrides the value for the profile settingca_bundle.export AWS_CA_BUNDLE=~/Desktop/Fiddler_Root_Certificate_Authority.pem -
Start capturing the traffic generated from the AWS CLI commands.
aws sts get-caller-identity
Resetting the AWS CLI to Default Settings
After the debugging of the request is over, reset the AWS_CA_BUNDLE environment variable by using the unset command.
unset AWS_CA_BUNDLE
You can also reset the Fiddler Proxy in your terminal application.
