TFTP: Missing Filename
This protocol anomaly is a TFTP Read or Write request that does not have a filename. This can indicate a malicious client or a tunneling attempt.
Extended Description
A protocol anomaly exists when there is a TFTP RRQ or WRQ request without a file name. Receiving such a packet may indicate an attempt to attack a system. The impact of such malformed requests depends entirely upon the implementation of TFTP that handles it.
