The vulnerability typically exists in applications that take user input (like a template name or a filename) and use it to build a path to a file on the disk without proper "sanitization."
: By repeating this sequence (e.g., five times), the attacker attempts to reach the "root" directory of the server, regardless of how deep the application is buried in the file structure. -template-..-2F..-2F..-2F..-2Froot-2F.aws-2Fcredentials
: This is the "holy grail" for an attacker targeting AWS infrastructure. It is the default location where the AWS Command Line Interface (CLI) stores sensitive access keys ( aws_access_key_id ) and secret keys ( aws_secret_access_key ). How the Vulnerability Occurs The vulnerability typically exists in applications that take
