====================================================================== 
4) Description of Vulnerability

Secunia Research has discovered a security issue in MDaemon, which can
be exploited by malicious, local users to gain escalated privileges.

The problem is caused due to the application by default being 
installed in the "MDaemon" folder in the system root with insecure
permissions (granting members of the "Users" group permissions to
create files and directories). This can be exploited by e.g. placing
a malicious RASAPI32.DLL or MPRAPI.DLL library in the "MDaemon\APP"
directory.

Successful exploitation allows execution of arbitrary code with SYSTEM
privileges.

NOTE: This is a general problem for the majority of Windows
applications when installed outside the "Program Files" folder due to
the way libraries are located.

Also, fans of "Colossal Cave Adventure" should try sending the
commands: "XYZZ" and "PLUG" to the POP3 service or "XYZZY" and "PLUGH"
to the ODMR service (port 366/TCP).

====================================================================== 
5) Solution 

Set secure permissions on the directory or install in the "Program
Files" folder (according to the vendor, this should not have an impact
on the functionality of the application).

====================================================================== 
6) Time Table 

29/08/2006 - Vendor notified.
31/08/2006 - Vendor response.
24/10/2006 - Vendor issues version 9.5.0, which does not address the 
             security issue correctly (just checks for the presence of
             RASAPI32.DLL in the application folder).
26/10/2006 - Vendor contacted again.
31/10/2006 - Vendor response.
16/11/2006 - Public disclosure.
