|
|
This module exploits a stack overflow in Novell's NetMail 3.52 IMAP AUTHENTICATE
|
|
GSSAPI command. By sending an overly long string, an attacker can overwrite the
|
|
buffer and control program execution. Using the PAYLOAD of windows/shell_bind_tcp
|
|
or windows/shell_reverse_tcp allows for the most reliable results.
