  IBM AlphaWorks TFTP Server for Java Directory Traversal
------------------------------------------------------------------------

SUMMARY

IBM's <http://alphaworks.ibm.com/tech/TFTP> AlphaWorks TFTP Server allows
Java programmers to incorporate a TFTP server into their code. A security
vulnerability in the product allows attackers to traverse outside the
normal bounding root directory of the TFTP server.

DETAILS

The IBM alphaWorks TFTP Server for Java is vulnerable to a 'standard'
directory traversal attack (i.e. ../../). This would allow an attacker to
either upload or download files to and from sensitive directories on the
remote computer that are outside the normally bounding root directory.
