4) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in LotusCMS, which 
can be exploited by malicious users and malicious people to compromise 
a vulnerable system.

1) Input passed via the "req" parameter to index.php (when system" is 
set to "Modules", "page" is set to "admin", and "active" is set to 
Menu") is not properly sanitised before being used in an "eval()" 
call. This can be exploited to execute arbitrary PHP code.

Successful exploitation of this vulnerability requires "editor" access.

2) Input passed via the "page" parameter to index.php is not properly 
sanitised in the "Router()" function in core/lib/router.php before 
being used in an "eval()" call. This can be exploited to execute 
arbitrary PHP code.

Successful exploitation of this vulnerability requires that
"magic_quotes_gpc" is disabled.
