PRIVATE Remote Exploit For IMAIL Smtp Server(1.2)

This is a remote exploit for IMAIL Smtp Server(1.2) version 8.01-8.11. The exploit is used to attack the hostname specified using the options provided. It supports win2k All version and IMail 8.01-11. The exploit uses the strcpy function to copy a buffer from src to dst, which can lead to a buffer overflow vulnerability. The exploit also connects back to an IP and port specified using the options. The bad characters used in the exploit are 0x00, 0x0a, and 0x25. The exploit also manipulates the PEB structure to hide its presence.

Mitigation:

Apply the patch provided by the vendor.
