During the scan, Kayran managed to find that the server provides detailed information about the Linux version being used. This information can be used to check what vulnerabilities might exist. And by doing so, assisting in launching targeted attacks later on.
An attacker could use the exposed information to exploit specific security vulnerabilities in the identified version. For example: there might be vulnerabilities in a certain web server versions that can allow an unauthorized attacker access to the server.
