CodeDeploy Appspec Configuration Detected

Synopsis

CodeDeploy Appspec Configuration Detected

Description

CodeDeploy `appspec.yml` is a configuration file used in AWS CodeDeploy deployments to define how application files should be copied and what lifecycle event hooks should be executed during the deployment process.

This plugin checks for the presence of the `appspec.yml` file in web applications. If this file is publicly accessible, it can lead to the exposure of sensitive information that could be exploited by attackers.

Solution

Ensure that the `appspec.yml` configuration file is not deployed with the application or, at least, is not exposed in a web server directory by setting proper permissions on it. If sensitive information like credentials are leaked in the exposed file, they should be revoked and reset on the affected assets.
