4) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in LotusCMS, which 
can be exploited by malicious users and malicious people to disclose 
sensitive information.

1) Input passed via the "active" parameter to index.php (when "system" 
is set to "Editor" and "page" is set to "editor") is not properly 
verified before being used to read files. This can be exploited to read
arbitrary files from local resources via directory traversal sequences 
and URL-encoded NULL bytes.

Successful exploitation of this vulnerability requires "editor" access.

2) Input passed via the "page" parameter to index.php is not properly 
verified in the "openFile()" function in core/model/PageModel.php 
before being used to read files. This can be exploited to read 
arbitrary files from local resources via directory traversal sequences 
and URL-encoded NULL bytes.

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

5) Solution 

Update to version 3.0.5.
