Most physical access vulnerabilities are, for the sake of cataloging, ignored unless the vulnerability is actually circumnavigating security put in place of stopping an attack. For example, smashing the computer with a hammer is not catalogued, while knowing a backdoor to the BIOS password would be listed. Local Access When a person has access to execute arbitrary commands on the host directly, they are considered to have “local” access. Some examples of this would be access a computer through the “telnet”, “remote shell”, or “secure remote shell” daemons.

Basically, any attempt to exploit the network topography at the data level would be considered a Man-in-the-Middle attack. Cumulative Tactics Tactics don’t have be to limited to a single approach per exploit, some exploits require combinations of tactics to be used to reach a single goal. Sample Vulnerability [DNS Race Condition, Rik Farrow] A vulnerability exists in DNS Bind that can allow an attacker to spoof their identity. If the attacker connects to a server with a name that is not already cached by the site’s DNS server, the DNS server will connect to its primary DNS server to receive the name for the host.

You may be able to create a root access account, but you cannot change the “original” root account) Appending Any Files with Security Compromising Payload By appending information to the end of an arbitrary file, it is usually trivial to gain higher access. The payload should be related directly with the service trying to be accessed such that it should give the highest amount of access possible. The following example will place a “+ +” into the root account’s Rservices trust file. The “+” is a wildcard, so the “+ +” will assume all people are trusted to try to log in as root and will allow the intruder to gain root access without supplying a password.
