The string you provided, callback-url=file:///home/*/.aws/credentials , describes a severe or Local File Inclusion (LFI) vulnerability. It indicates that an application is being instructed to read and exfiltrate highly sensitive AWS authentication keys from the local file system. Executive Summary Vulnerability Type: Local File Inclusion (LFI) / SSRF.
: The URI scheme used to access local files on the server's disk rather than an external web address. callback-url-file-3A-2F-2F-2Fhome-2F-2A-2F.aws-2Fcredentials
Short-term (1–7 days)
Now that we've dissected the URL and explored the AWS credentials file, let's discuss the possible scenarios where the callback-url-file-3A-2F-2F-2Fhome-2F-2A-2F.aws-2Fcredentials might appear. Server-Side Request Forgery (SSRF) The string you provided,
: By URL-encoding the path to the AWS credentials file ( file:///home/*/.aws/credentials ), an attacker could trick a vulnerable service into reading the local file and sending its contents to an attacker-controlled server as part of a "callback" mechanism. file:/// : The URI scheme used to access
When decoded, the URL component file-3A-2F-2F-2Fhome-2F-2A-2F.aws-2Fcredentials translates to: file:///home/*/.aws/credentials .
