Packet Storm Security Exploits
This Metasploit module exploits a vulnerability found in Distinct TFTP server. The software contains a directory traversal vulnerability that allows a remote attacker to write arbitrary file to the file system, which results in code execution under the context of 'SYSTEM'.

Packet Storm Security Exploits
This Metasploit module exploits a vulnerability found in TFTP Server 1.4 ST. The flaw is due to the way TFTP handles the filename parameter extracted from a WRQ request. The server will append the user-supplied filename to TFTP server binary's path without any bounds checking, and then attempt to open this with a fopen(). Since this isn't a valid file path, fopen() returns null, which allows the corrupted data to be used in a strcmp() function, causing an access violation. Since the offset is sensitive to how the TFTP server is launched, you must know in advance if your victim machine launched the TFTP as a 'Service' or 'Standalone' , and then manually select your target accordingly. A successful attempt will lead to remote code execution under the context of SYSTEM if run as a service, or the user if run as a standalone. A failed attempt will result a denial-of-service.

Packet Storm Security Exploits
This Metasploit module exploits a buffer overflow in OpenTFTP Server SP 1.4. The vulnerable condition triggers when the TFTP opcode is configured as an error packet, the TFTP service will then format the message using a sprintf() function, which causes an overflow, therefore allowing remote code execution under the context of SYSTEM. The offset (to EIP) is specific to how the TFTP was started (as a 'Stand Alone', or 'Service'). By default the target is set to 'Service' because that's the default configuration during OpenTFTP Server SP 1.4's installation.

The TFTPUtil GUI server version 1.4.5 can be denial of serviced by sending a specially crafted read request. Depending on the setup, sending write request "\x00\x02" may also work. This is written as a Metasploit module.
