CAPEC-40: Manipulating Writeable Terminal Devices

Description
This attack exploits terminal devices that allow themselves to be written to by other users. The attacker sends command strings to the target terminal device hoping that the target user will hit enter and thereby execute the malicious command with their privileges. The attacker can send the results (such as copying /etc/passwd) to a known directory and collect once the attack has succeeded.
Extended Description

RFID (Radio Frequency Identification) are passive devices which consist of an integrated circuit for processing RF signals and an antenna. RFID devices are passive in that they lack an on on-board power source. The majority of RFID chips operate on either the 13.56 MHz or 135 KHz frequency. The chip is powered when a signal is received by the antenna on the chip, powering the chip long enough to send a reply message. An attacker is able to capture and analyze RFID data by either stimulating the chip to respond or being proximate to the chip when it sends a response to a remote transmitter. This allows the attacker to duplicate the signal and conduct attacks such as gaining unauthorized access to a building or impersonating a user's identification.
