TFTP: Empty Filename
This protocol anomaly is a TFTP Read or Write packet that has an empty filename.
Extended Description
A protocol anomaly exists when a TFTP RRQ or WRQ request has an empty file name. Receiving such a packet may indicate an attempt to attack a system. The impact of a TFTP RRQ or WRQ request with an empty file name depends entirely upon the implementation of TFTP that handles it.
