TFTP: Filename Not NULL Terminated

This protocol anomaly is a TFTP Read or Write request that does not have a NULL terminator in the filename. RFC-1350 specifies that a zero byte should follow the filename specification in a TFTP message.

Extended Description

A protocol anomaly exists when a TFTP RRQ or WRQ request does not have a NULL byte following a file name. Receiving such a packet may indicate an attempt to attack a system. The impact of such a malformed packet depends entirely upon the implementation of TFTP that handles it.
