Description:

engine developed in PHP with MySQL back-end.
It manages entries , articles , hit-counters , quizzes,surveys and it has a
very easy to modify look and feel.

-----------------------------------------
SECURITY HOLES FOUND and PROOFS OF CONCEPT:
-----------------------------------------

I encountered few security holes related with path disclosures  and Cross
Site Scripting vulnerabilities in Search module.

---------------------------
|    PATH DISCLOSURES     |
---------------------------

There are some path disclosures in some files of pMachine , with this you
can get the real (local) installation path of
the pMachine scripts.

Proof of Concepts:

http://[TARGET]/[pMachine PATH]/index.php?sfx=./nothing
http://[TARGET]/[pMachine PATH]/inc.lib.php?sfx=./nothing
http://[TARGET]/[pMachine PATH]/inc.cp.php?sfx=./nothing
http://[TARGET]/[pMachine PATH]/lib/weblog.add.php <-- access directly
http://[TARGET]/[pMachine PATH]/lib/comment.add.php <-- access directly

Possible other files using this variable (sfx) are vulnerable.

---------------------------
|  CROSS SITE SCRIPTING   |
---------------------------

There are some security holes in the Search module that it's located in
/search/ directory.
You can inject HTML code and Script Code in the query of the Search , this
code will be executed in the user side.

Proof of Concepts:

http://[TARGET]/[pMachine Public Path]/search/index.php?weblog=[THE
WEBLOG]&keywords=[XSS ATTACK CODE]
