DESCRIPTION:
John Leitch has discovered a vulnerability in Techphoebe QuickShare
File Server, which can be exploited by malicious users to disclose
potentially sensitive information and compromise a vulnerable
system.

The vulnerability is caused due to the HTTP server not properly
filtering directory traversal sequences, which can be exploited to
e.g. read or write arbitrary files outside the server's root
directory by sending specially crafted requests to the server.

Successful exploitation to write to files outside of the server's
root directory requires write privileges.

The vulnerability is confirmed in version 1.2. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
John Leitch
