Vulnerable Systems:
* MDaemon version 9.0.5
* MDaemon version 9.0.6
* MDaemon version 9.51
* MDaemon version 9.53
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).
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).
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.
